1 Chapter 1 Introduction This Chapter provides an overview of the Wireless ADSL Modem Router's features and capabilities. Congratulations on the purchase of your new Wireless ADSL Modem Router. The Wireless ADSL Modem Router is a multi-function device providing the following services: • ADSL Modem. • Shared Broadband Internet Access for all LAN users. • Wireless Access Point for 802.11n, 802.11b and 802.11g Wireless Stations. • 4-Port Switching Hub for 10BaseT or 100BaseT connections. Wireless ADSL Modem Router Features The Wireless ADSL Modem Router incorporates many advanced features, carefully designed to provide sophisticated functions while being easy to use. Internet Access Features • Shared Internet Access. All users on the LAN or WLAN can access the Internet through the Wireless ADSL Modem Router, using only a single external IP Address. The local (invalid) IP Addresses are hidden from external sources. This process is called NAT (Network Address Translation). • Built-in ADSL Modem. The Wireless ADSL Modem Router has a built-in ADSL modem, supporting all common ADSL connections. 1
2 • IPoA, PPPoE, PPPoA, Direct Connection Support. The Wireless ADSL Modem Router supports all common connection methods. • Auto-detection of Internet Connection Method. In most situations, the Wireless ADSL Modem Router can test your ADSL and Internet connection to determine the con-nection method used by your ISP. • Static or Dynamic IP Address. On the Internet (ADSL port) connection, the Wireless ADSL Modem Router supports both Dynamic IP Address (IP Address is allocated on connection) and Static (Fixed) IP Address. Advanced Internet Functions • Application Level Gateways (ALGs). Applications which use non-standard connec-tions or port numbers are normally blocked by the Firewall. The ability to define and allow such applications is provided, to enable such applications to be used normally. • Port Triggering. This feature, also called Special Applications, allows you to use Internet applications which normally do not function when used behind a firewall. • Port Forwarding. This feature allows Internet users to access Internet servers on your LAN. The required setup is quick and easy. • Dynamic DNS Support. DDNS, when used with the Virtual Servers feature, allows users to connect to Servers on your LAN using a Domain Name, even if you have a dy-namic IP address which changes every time you connect. • URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN users. • Scheduling. Both the URL Filter and Firewall rules can be scheduled to operate only at certain times. This provides great flexibility in controlling Internet -bound traffic. • Logs. Define what data is recorded in the Logs, and optionally send log data to a Syslog Server. Log data can also be E-mailed to you. • VPN Pass through Support. PCs with VPN (Virtual Private Networking) software using PPTP, L2TP and IPSec are transparently supported - no configuration is required. • Multi-PVC Support. A permanent virtual circuit (PVC) can provide a continuous connection between two or more points when needed without having to reserve a specific physical path in advance. In this way, many companies can share a common pool of cir-cuits. (Please note: auto-detect connection setup in Setup Wizard does not support Multi-PCV. If you would like to enable the Multi-PVC feature, please use manual connection method instead.) Wireless Features • Standards Compliant. The Wireless ADSL Modem Router complies with the IEEE802.11g (DSSS) specifications for Wireless LANs. • Supports Pre-N Wireless Stations. The 802.11n Draft standard provides for backward compatibility with the 802.11b standard, so 802.11n, 802.11b and 802.11g Wireless sta-tions can be used simultaneously. • WEP support. Support for WEP (Wired Equivalent Privacy) is included. Key sizes of 64 Bit and 128 Bit are supported. WEP encrypts any data before transmission, providing protection against snoopers.
3 • WPA-PSK support. Like WEP, WPA-PSK encrypts any data before transmission, providing protection against snoopers. The WPA-PSK is a later standard than WEP, and provides both easier configuration and greater security than WEP. • WPA2-PSK support. Support for WPA2 is also included. WPA2 uses the extremely secure AES encryption method. • 802.1x Support. Support for 802.1x mode is included, providing for the industrial-strength wireless security of 802.1x authentication and authorization. • Wireless MAC Access Control. The Wireless Access Control feature can check the MAC address (hardware address) of Wireless stations to ensure that only trusted Wireless Stations can access your LAN. • Simple Configuration. If the default settings are unsuitable, they can be changed quickly and easily. • WPS Support. WPS (Wi-Fi Protected Setup) can simplify the process of connecting any device to the wireless network by using the Push Button Configuration (PBC) on the Wireless Access Point, or entering a PIN code if there's no button. • WDS Support. Support for WDS (Wireless Distribution System) allows the Wireless Access Point to act as a Wireless Bridge. Both Point-to-Point and Multi-Point Bridge modes are supported. LAN Features • 4-Port Switching Hub. The Wireless ADSL Modem Router incorporates a 4-port 10/100BaseT switching hub, making it easy to create or extend your LAN. • DHCP Server Support. Dynamic Host Configuration Protocol provides a dynamic IP address to PCs and other devices upon request. The Wireless ADSL Modem Router can act as a DHCP Server for your local LAN and WLAN devices. Configuration & Management • Easy Setup. Use your WEB browser from anywhere on the LAN or WLAN for configu-ration. • Configuration File Upload/Download. Save (download) the configuration data from the Wireless ADSL Modem Router to your computer, and restore (upload) a previously-saved configuration file to the Wireless ADSL Modem Router. • Remote Management. The Wireless ADSL Modem Router can be managed from any PC on your LAN or Wireless LAN. And, if the Internet connection exists, it can also (op-tionally) be configured via the Internet. • Network Diagnostics. You can use the Wireless ADSL Modem Router to perform a Ping or DNS lookup. Security Features • Password - protected Configuration. Password protection is provided to prevent unauthorized users from modifying the configuration data and settings. • Wireless LAN Security. WPA-802.1x, WPA2-802.1x and WEP and Wireless access control by MAC address are all supported. The MAC-level access control feature can be used to prevent unknown wireless stations from accessing your LAN.
4 • NAT Protection. An intrinsic side effect of NAT (Network Address Translation) tech-nology is that by allowing all LAN users to share a single IP address, the location and even the existence of each computer is hidden. From the external viewpoint, there is no network, only a single device - the Wireless ADSL Modem Router. • Firewall. All incoming data packets are monitored and all incoming server requests are filtered, thus protecting your network from malicious attacks from external sources. • Protection against DoS attacks. DoS (Denial of Service) attacks can flood your Internet connection with invalid packets and connection requests, using so much band-width and so many resources that Internet access becomes unavailable. The Wireless ADSL Modem Router incorporates protection against DoS attacks.

LAN IP Address Enter the IP address of the device on your LAN which will receive the data on this VC. • For Video-on-Demand, this would be the IP address of your SetTop Box. • For VoIP, this would be the IP address of your VoIP TA. • Note that this IP address does not have to be in the same IP ad-dress range as other devices on your local LAN.
23 Main Screen After finishing the Setup Wizard, the browse will back to main screen. Main Menu The main menu, on the left, contains links to the most-commonly used screen. To see the links to the other available screens, click "Advanced" or "Administration". The main menu also contains one (1) button: • Log Out - When finished, you should click this button to logout. Navigation & Data Input • Use the menu bar on the left of the screen, and the "Back" button on your Browser, for navigation. • Changing to another screen without clicking "Save" does NOT save any changes you may have made. You must "Save" before changing screens or your data will be ignored. On each screen, clicking the "Help" button will display help for that screen.
24 LAN Screen Use the LAN link on the main menu to reach the LAN screen. An example screen is shown below. LAN Screen TCP/IP IP Address IP address for the Wireless ADSL Modem Router, as seen from the local LAN. Use the default value unless the address is already in use or your LAN is using a different IP address range. In the latter case, enter an unused IP Address from within the range used by your LAN. Subnet Mask The default value 255.255.255.0 is standard for small (class "C") networks. For other networks, use the Subnet Mask for the LAN segment to which the Wireless ADSL Modem Router is attached (the same value as the PCs on that LAN segment). DHCP Server • If Enabled, the Wireless ADSL Modem Router will allocate IP Addresses to PCs (DHCP clients) on your LAN when they start up. The default (and recommended) value is Enabled. • If you are already using a DHCP Server, this setting must be Disabled, and the existing DHCP server must be re-configured to treat the Wireless ADSL Modem Router as the default Gateway. See the following section for further details. • The Start IP Address and Finish IP Address fields set the values used by the DHCP server when allocating IP Addresses to DHCP clients. This range also determines the number of DHCP clients supported. Enter the desired value for the Lease Time, which should be between 1 and 7. See the following section for further details on using DHCP.
25 DHCP What DHCP Does A DHCP (Dynamic Host Configuration Protocol) Server allocates a valid IP address to a DHCP Client (PC or device) upon request. • The client request is made when the client device starts up (boots). • The DHCP Server provides the Gateway and DNS addresses to the client, as well as allocating an IP Address. • The Wireless ADSL Modem Router can act as a DHCP server. • Windows other non-Server versions of Windows will act as a DHCP client. This is the default Windows setting for the TCP/IP network protocol. However, Windows uses the term Obtain an IP Address automatically instead of "DHCP Client". • You must NOT have two (2) or more DHCP Servers on the same LAN segment. (If your LAN does not have other Routers, this means there must only be one (1) DHCP Server on your LAN.) Using the Wireless ADSL Modem Router's DHCP Server This is the default setting. The DHCP Server settings are on the LAN screen. On this screen, you can: • Enable or Disable the Wireless ADSL Modem Router's DHCP Server function. • Set the range of IP Addresses allocated to PCs by the DHCP Server function. You can assign Fixed IP Addresses to some devices while using DHCP, provided that the Fixed IP Addresses are NOT within the range used by the DHCP Server. Using another DHCP Server You can only use one (1) DHCP Server per LAN segment. If you wish to use another DHCP Server, rather than the Wireless ADSL Modem Router's, the following procedure is required. • Disable the DHCP Server feature in the Wireless ADSL Modem Router. This setting is on the LAN screen. • Configure the DHCP Server to provide the Wireless ADSL Modem Router's IP Address as the Default Gateway. To Configure your PCs to use DHCP This is the default setting for TCP/IP for all non-Server versions of Windows. See Chapter 4 - Client Configuration for the procedure to check these settings.
26 Wireless Screen The Wireless ADSL Modem Router's settings must match the other Wireless stations. Note that the Wireless ADSL Modem Router will automatically accept both 802.11b and 802.11g connections, and no configuration is required for this feature. To change the Wireless ADSL Modem Router's default settings for the Wireless Access Point feature, use the Wireless link on the main menu to reach the Wireless screen. An example screen is shown below. Wireless Screen Region Region Select the correct domain for your location. It is your responsibility to ensure: • That the Wireless ADSL Modem Router is only used in domains for which is licensed. • That you select the correct domain, so that only the legal channels for that domain can be selected.
27 Multi SSID SSID With Multiple SSIDs, you can have 2 SSIDs on one AP. For example, a Guest SSID without encryption for visitors to have Internet access only, and a Admin SSID with encryption for private use to secure your company resources. Select the desired SSID from the list to configure. SSID 1/SSID 2 This is also called the "Network Name". • If using an ESS (Extended Service Set, with multiple access points) this ID is called an ESSID (Extended Service Set Identifi-er). • To communicate, all Wireless stations should use the same SSID/ESSID. Broadcast SSID If enabled, the Wireless ADSL Modem Router will broadcast its SSID. This allows PCs and other wireless stations to detect this Access Point and use the correct SSID. If disabled, PC users will have to manually enter the SSID and other details of the wireless interface before they can connect to this Access Point. Isolation within SSID If Enabled, devices that have the same SSID will not be able to see each other. Security Setting The current Wireless security is displayed. The default value is Dis-abled. Configure SSID 1/SSID2 Button Click this button to access the Wireless security sub-screen, and view or change the settings. See the following section for details. Options 802.11 Mode Select the desired mode: • 11b + 11g - Both 802.11b and 802.11g Wireless stations will be able to use the Wireless Broadband Router. • 11b/g/N (20MHz) - 802.11.g, 802.11b and 802.11n (20MHz) Wireless stations can use the Wireless Broadband Router. • 11b/g/N (20/40MHz) - 802.11b, 802.11g and 802.11n (20MHz or 40MHz) Wireless stations can use the Wireless Broadband Router. • Disable: Wireless function is off Channel No. Select the Channel you wish to use on your Wireless LAN. • If you experience interference (shown by lost connections and/or slow data transfers) you may need to experiment with different channels to see which is the best. • If using multiple Access Points, adjacent Access Points should use different Channels to reduce interference. Extension Channel Select either UP or DOWN from the list. WMM Support Enable or disable this feature as required.
28 Access Point Allow access by … Use this feature to determine which Wireless stations can use the Access Point. The options are: • All Wireless Stations - All wireless stations can use the access point, provided they have the correct SSID and security settings. • Trusted Wireless stations only - Only wireless stations you designate as "Trusted" can use the Access Point, even if they have the correct SSID and security settings. This feature uses the MAC address to identify Wireless stations. The MAC address is a low-level network identifier which is unique to each PC or network device. To define the trusted wireless stations, use the "Set Stations" but-ton. Set Stations Button Click this button to manage the trusted PC database. WiFi Protect Setup Enable WPS Enable this if you want to use Wireless WPS function. AP PIN Code Click the Regenerate button to have the new pin code in the field. Input Client PIN Code Enter the client’s PIN code in the field and click OK to add the client device. WDS Enable WDS This feature allows you to make a completely wireless network by using multiple access points without connecting them with a wire LAN. In order to make the WDS working successfully, the access point must use the same channel, SSID, as well as the wireless encryption method. MAC Address List Enter the MAC address(es) of the AP(s) into the fields to allow the following access points to be connected to the wireless router.
29 Wireless Security This screen is accessed by clicking the "Configure SSID" button on the Wireless screen. There are 3 options for Wireless security: • Disabled - no data encryption is used. • WEP - data is encrypted using the WEP standard. • WPA-PSK - data is encrypted using the WPA-PSK standard. This is a later standard than WEP, and provides much better security than WEP. If all your Wireless stations support WPA-PSK, you should use WPA-PSK rather than WEP. • WPA2-PSK - This is a further development of WPA-PSK, and offers even greater securi-ty, using the AES (Advanced Encryption Standard) method of encryption. • Mixed WPA-PSK/WAP2-PSK - This method, sometimes called "Mixed Mode", allows clients to use EITHER WPA-PSK OR WPA2-PSK. • WPA-802.1x - This version of WPA requires a Radius Server on your LAN to provide the client authentication according to the 802.1x standard. Data transmissions are encrypted using the WPA standard.

83 Chapter 6 Advanced Administration This Chapter explains the settings available via the "Administration" section of the menu. Overview Normally, it is not necessary to use these screens, or change any settings. These screens and settings are provided to deal with non-standard situations, or to provide additional options for advanced users. The available settings and features are: PC Database This is the list of PCs shown when you select the "DMZ PC" or a "Virtual Server". This database is maintained automatically, but you can add and delete entries for PCs which use a Fixed (Static) IP Address. Config File Backup or restore the configuration file for the Wireless ADSL Modem Router. This file contains all the configuration data. Logs & E-mail View or clear all logs, set E-Mailing of log files and alerts. Diagnostics Perform a Ping or DNS Lookup. Remote Admin Allow settings to be changed from the Internet. Routing Only required if your LAN has other Routers or Gateways. Upgrade Firmware Upgrade the Firmware (software) installed in your Wireless ADSL Modem Router. 6
84 PC Database The PC Database is used whenever you need to select a PC (e.g. for the "DMZ" PC). • It eliminates the need to enter IP addresses. • Also, you do not need to use fixed IP addresses on your LAN. However, if you do use a fixed IP address on some devices on your LAN, you should enter details of each such device into the PC database, using the PC Database screen. PC Database Screen An example PC Database screen is shown below. • PCs which are "DHCP Clients" are automatically added to the database, and updated as required. • The Wireless ADSL Modem Router uses the "Hardware Address" to identify each PC, not the name or IP address. The "Hardware Address" can only change if you change the PC's network card or adapter. PC Database Screen Known PCs This lists all current entries. Data displayed is name (IP Address) type. The "type" indicates whether the PC is connected to the LAN. Name If adding a new PC to the list, enter its name here. It is best if this matches the PC's "hostname". IP Address Enter the IP Address of the PC. The PC will be sent a "ping" to deter-mine its hardware address. If the PC is not available (not connected, or not powered On) you will not be able to add it. Buttons Refresh Update the data on screen.
85 Config File This feature allows you to download the current settings from the Wireless ADSL Modem Router, and save them to a file on your PC. You can restore a previously-downloaded configuration file to the Wireless ADSL Modem Router, by uploading it to the Wireless ADSL Modem Router. This screen also allows you to set the Wireless ADSL Modem Router back to its factory default configuration. Any existing settings will be deleted. An example Config File screen is shown below. Config File Screen Backup Config Use this to download a copy of the current configuration, and store the file on your PC. Click Backup to start the download. Restore Config This allows you to restore a previously-saved configuration file back to the Wireless ADSL Modem Router. Click Browse to select the configuration file, then click Restore to upload the configuration file. WARNING! Uploading a configuration file will destroy (overwrite) ALL of the existing settings. Default Config Clicking the Factory Defaults button will reset the Wireless ADSL Modem Router to its factory default settings. WARNING! This will delete ALL of the existing settings.
86 Logs The Logs record various types of activity on the Wireless ADSL Modem Router. This data is useful for troubleshooting, but enabling all logs will generate a large amount of data and adversely affect performance. Since only a limited amount of log data can be stored in the Wireless ADSL Modem Router, log data can also be E-mailed to your PC. Use the E-mail screen to configure this feature. Logs Screen Logs Current Time The current time on the Wireless ADSL Modem Router is dis-played. Log Data Current log data is displayed in this panel. Buttons There are three (3) buttons • Refresh - Update the log data. • Clear Log - Clear the log, and restart it. This makes new messages easier to read. • Send Log - E-mail the log immediately. This is only func-tional if the E-mail screen has been configured.
87 Include in Log Include (Checkboxes) Use these checkboxes to determine which events are included in the log. Checking all options will increase the size of the log, so it is good practice to disable any events which are not really re-quired. • Attempted access to blocked sites - If checked, attempted Internet accesses which were blocked are logged. • Connections to the Web-based interface of this Router - If checked, this will log connections TO this Router, rather than through this Router to the Internet. • Router operation - If checked, other Router operations (not covered by the selections above) will be logged. • Known DoS attacks and Port Scans - If checked, Denial of Service attacks, as well as port scans, will be logged. Syslog Disable Data is not sent to a Syslog Server. Broadcast on LAN The Syslog data is broadcast, rather than sent to a specific Syslog server. Use this if your Syslog Server does not have a fixed IP address. Send to this Syslog Server If your Syslog server has a fixed IP address, select this option, and enter the IP address of your Syslog server.
88 E-mail This screen allows you to E-mail Logs and Alerts. A sample screen is shown below. E-mail Screen E-Mail Notification Turn E-mail Notification on Check this box to enable this feature. If enabled, the E-mail address information (below) must be provided. Send to this E-mail address Enter the E-mail address the Log is to be sent to. Outgoing (SMTP) Mail Server Enter the address or IP address of the SMTP (Simple Mail Transport Protocol) Server you use for outgoing E-mail. Mail Sender Address Enter the mail address of the sender. The E-mail will also show this address as the Sender's address. My SMTP Mail Server requires authentication To stop spanners, many SMTP mail servers require you to log in to send mail. In this case, enable this checkbox, and enter the login information (User name and Password) in the fields below. User Name If you have enabled "My SMTP Mail Server requires authentication" above, enter the User Name required to login to your SMTP Server. Password If you have enabled "My SMTP Mail Server requires authentication" above, enter the password required to login to your SMTP Server.
89 E-mail Alerts Send E-mail alerts immediately You can choose to have alerts E-mailed to you, by checking the desired checkboxes. The Broadband ADSL Router can send an immediate alert when it detects a significant security incident such as • A known hacker attack is directed at your IP address • A computer on the Internet scans your IP address for open ports • Someone on your LAN (Local Area Network) tries to visit a blocked site. E-mail Logs Send Logs Select the desired option for sending the log by E-mail. • Never (default) - This feature is disabled; Logs are not sent. • When log is full - The time is not fixed. The log will be sent when the log is full, which will depend on the volume of traffic. • Hourly, Daily, Weekly... - The log is sent on the interval specified. • If Daily is selected, the log is sent at the time specified. Select the time of day you wish the E-mail to be sent. • If Weekly is selected, the log is sent once per week, on the specified day, at the specified time. Select the day and the time of day you wish the E-mail to be sent. Note: If the log is full before the time specified to send it, it will be sent regardless of the day and time specified.
90 Diagnostics This screen allows you to perform a "Ping" or a "DNS lookup". These activities can be useful in solving network problems. An example Network Diagnostics screen is shown below. Network Diagnostics Screen Ping IP Address Enter the IP address you wish to ping. The IP address can be on your LAN, or on the Internet. Note that if the address is on the Internet, and no connection currently exists, you could get a "Timeout" error. In that case, wait a few seconds and try again. Ping Button After entering the IP address, click this button to start the "Ping" procedure. The results will be displayed in the Ping Results pane. DNS Lookup Internet Name Enter the Domain name or URL for which you want a DNS (Domain Name Server) lookup. Note that if the address in on the Internet, and no connection currently exists, you could get a "Timeout" error. In that case, wait a few seconds and try again. Lookup Button After entering the Domain name/URL, click this button to start the "DNS Lookup" procedure. Routing Display Click this button to display the internal routing table. This informa-tion can be used by Technical Support and other staff who understand Routing Tables.
91 Remote Administration If enabled, this feature allows you to manage the Wireless ADSL Modem Router via the Internet. Remote Administration Screen Remote Administration Enable Remote Management Check to allow administration/management via the Internet. (To connect, see below). If Disabled, this device will ignore Administration connection attempts from the Internet. Current IP Address This is the current address you will use when accessing this device from the Internet. To connect, see details and an example below. Port Number Enter a port number between 1 and 65535. The default for HTTP (Web) connections is port 80, but using port 80 will prevent the use of a Web "Virtual Server" on your LAN. So using a different port number is recommended. The default value is 8080. The port number must be specified in your Browser when you connect. See the following section for details. Access Permission Allow Remote Access Select the desired option. • Everyone - allow access by everyone on the Internet. • Only This Computer - allow access by only one IP address. Enter the desired IP address. • IP Address Range - allow access from a range of IP addresses on the Internet. Enter a beginning and ending IP address to de-fine the allowed range. For security, you should restrict access to as few external IP ad-dresses as practical.
92 To connect from a remote PC via the Internet 1. Ensure your Internet connection is established, and start your Web Browser. 2. In the "Address" bar, enter "HTTP://" followed by the Internet IP Address of the Wireless ADSL Modem Router. If the port number is not 80, the port number is also required. (Af-ter the IP Address, enter ":" followed by the port number.) e.g. HTTP://123.123.123.123:8080 This example assumes the WAN IP Address is 123.123.123.123, and the port number is 8080. 3. You will then be prompted for the login name and password for this device.
93 Routing Overview • If you don't have other Routers or Gateways on your LAN, you can ignore the "Routing" page completely. • If the Wireless ADSL Modem Router is only acting as a Gateway for the local LAN segment, ignore the "Routing" page even if your LAN has other Routers. • If your LAN has a standard Router (e.g. Cisco) on your LAN, and the Wireless ADSL Modem Router is to act as a Gateway for all LAN segments, enable RIP (Routing Infor-mation Protocol) and ignore the Static Routing table. • If your LAN has other Gateways and Routers, and you wish to control which LAN seg-ments use each Gateway, do NOT enable RIP (Routing Information Protocol). Configure the Static Routing table instead. (You also need to configure the other Routers.) • If using Windows 2000 Data center Server as a software Router, enable RIP on the Wire-less ADSL Modem Router, and ensure the following Windows 2000 settings are correct: • Open Routing and Remote Access • In the console tree, select Routing and Remote Access, [server name], IP Routing, RIP • In the "Details" pane, right-click the interface you want to configure for RIP version 2, and then click "Properties". • On the "General" tab, set Outgoing packet protocol to "RIP version 2 broadcast", and Incoming packet protocol to "RIP version 1 and 2". Routing Screen The routing table is accessed by the Routing link on the Administration menu. Using this Screen Generally, you will use either RIP (Routing Information Protocol) OR the Static Routing Table, as explained above, although is it possible to use both methods simultaneously. Static Routing Table • If RIP is not used, an entry in the routing table is required for each LAN segment on your Network, other than the segment to which this device is attached. • The other Routers must also be configured. See Configuring Other Routers on your LAN later in this chapter for further details and an example.
94 Routing Screen RIP RIP Direction Select the desired RIP Direction. RIP Version Choose the RIP Version for the Server. Static Routing Static Routing Table Entries This list shows all entries in the Routing Table. • This area shows details of the selected item in the list. • Change any the properties as required, then click the "Edit" button to save the changes to the selected entry. Buttons Add Add a new entry to the Static Routing table, using the data shown in the "Properties" area on screen. The entry selected in the list is ignored, and has no effect. Edit Update the current Static Routing Table entry, using the data shown in the table area on screen. Delete Delete the current Static Routing Table entry. Save Save the RIP setting. This has no effect on the Static Routing Table. Configuring Other Routers on your LAN It is essential that all IP packets for devices not on the local LAN be passed to the Wireless ADSL Modem Router, so that they can be forwarded to the external LAN, WAN, or Internet. To achieve this, the local LAN must be configured to use the Wireless ADSL Modem Router as the Default Route or Default Gateway. Local Router The local router is the Router installed on the same LAN segment as the Wireless ADSL Modem Router. This router requires that the Default Route is the Wireless ADSL Modem Router itself. Typically, routers have a special entry for the Default Route. It should be confi-gured as follows.
95 Destination IP Address Normally 0.0.0.0, but check your router documentation. Network Mask Normally 0.0.0.0, but check your router documentation. Gateway IP Address The IP Address of the Wireless ADSL Modem Router. Metric 1 Other Routers on the Local LAN Other routers on the local LAN must use the Wireless ADSL Modem Router's Local Router as the Default Route. The entries will be the same as the Wireless ADSL Modem Router's local router, with the exception of the Gateway IP Address. • For a router with a direct connection to the Wireless ADSL Modem Router's local Router, the Gateway IP Address is the address of the Wireless ADSL Modem Router's local router. • For routers which must forward packets to another router before reaching the Wireless ADSL Modem Router's local router, the Gateway IP Address is the address of the inter-mediate router. Static Routing - Example For the Wireless ADSL Modem Router's Routing Table For the LAN shown above, with 2 routers and 3 LAN segments, the Wireless ADSL Modem Router requires 2 entries as follows. Entry 1 (Segment 1) Destination IP Address 192.168.20.0 Network Mask 255.255.255.0 (Standard Class C) Gateway IP Address 192.168.10.100 (Wireless ADSL Modem Router's local Router)
96 Metric 2 Entry 2 (Segment 2) Destination IP Address 192.168.30.0 Network Mask 255.255.255.0 (Standard Class C) Gateway IP Address 192.168.10.100 Metric 3 For Router A's Default Route Destination IP Address 0.0.0.0 Network Mask 0.0.0.0 Gateway IP Address 192.168.10.1 (Wireless ADSL Modem Rou-ter's IP Address) For Router B's Default Route Destination IP Address 0.0.0.0 Network Mask 0.0.0.0 Gateway IP Address 192.168.20.50 (Wireless ADSL Modem Router's local router)
97 Upgrade Firmware The firmware (software) in the Wireless ADSL Modem Router can be upgraded using your Web Browser. You must first download the upgrade file, then select Upgrade Firmware on the Administra-tion menu. You will see a screen like the following. To perform the Firmware Upgrade: 1. Click the Browse button and navigate to the location of the upgrade file. 2. Select the upgrade file. Its name will appear in the Upgrade File field. 3. Click the Upload button to commence the firmware upgrade. The Wireless ADSL Modem Router is unavailable during the upgrade process, and must restart when the upgrade is completed. Any connections to or through the Wireless ADSL Modem Router will be lost.
98 Chapter 7 Modem Mode This Chapter explains configuration and operation when in Modem Mode (al-so known as Bridge Mode) Overview There are two modes available on the Mode screen. • Router - Both the ADSL Modem and the Router features are operational. In this mode, this device can provide shared Internet Access to all your LAN users. Also, by default, it acts a DHCP Server, providing an IP address and related information to all Wireless and LAN users. • Modem (Bridge Mode) - Only the ADSL Modem component is operational. All Router features are disabled. This device is "transparent" - it does not perform any operations or make any changes to the network traffic passing through it. You need to have a DHCP Server on your LAN to provide IP addresses to the Wireless clients using this Access Point. This Chapter describes operation while in Modem Mode (Bridge Mode) Management Connections When this device restarts in Modem mode, the IP address does not change, but the DHCP server is disabled. However, your PC will usually retain the IP address provided by the DHCP Server, so the connection will be automatically re-established. You then need to ensure that the IP address of this modem is suitable for your LAN. • You need to have a DHCP Server on your LAN to provide IP addresses to the Wireless clients using this Access Point. • This Modem/AP must be a valid device on your LAN, to allow management connections. You must assign a (fixed) IP address which is within the address range used on your LAN, but not within the address range used by your DHCP server. When you connect in future, just connect normally, using the IP address you assigned. 1. Start your WEB browser. 2. In the Address box, enter "HTTP://" and the current IP Address of the Wireless ADSL Modem, as in this example, which uses the Wireless ADSL Modem's default IP Address: HTTP://192.168.10.1 3. When prompted for the User name and Password, enter admin for the user name, and password for the password. (The password is the same regardless of the mode setting.) 7
99 Modem Mode Main Screen In the Device Mode drop down menu, select Modem(Modem only) and click “Save”. The main screen will look like the example below. Note: When choosing Modem Mode, some of the Router options will not available for Modem mode. The detail information as showed below. • LAN – Allows user to set IP address and submask

No routing will be performed, and no client login will be done. If a client login is required, it must be performed by your Rou-ter/Gateway or by software on your PC.
104 Appendix A Troubleshooting This Appendix covers the most likely problems and their solutions. Overview This chapter covers some common problems that may be encountered while using the Wireless ADSL Modem Router and some possible solutions to them. If you follow the suggested steps and the Wireless ADSL Modem Router still does not function properly, contact your dealer for further advice. General Problems Problem 1: Can't connect to the Wireless ADSL Modem Router to configure it. Solution 1: Check the following: • The Wireless ADSL Modem Router is properly installed, LAN connec-tions are OK, and it is powered ON. • Ensure that your PC and the Wireless ADSL Modem Router are on the same network segment. (If you don't have a router, this must be the case.) • If your PC is set to "Obtain an IP Address automatically" (DHCP client), restart it. • If your PC uses a Fixed (Static) IP address, ensure that it is using an IP Address within the range 192.168.10.2 to 192.168.10.254 and thus compatible with the Wireless ADSL Modem Router's default IP Ad-dress of 192.168.10.1. Also, the Network Mask should be set to 255.255.255.0 to match the Wireless ADSL Modem Router. In Windows, you can check these settings by using Control Panel-Network to check the Properties for the TCP/IP protocol. Internet Access Problem 1: When I enter a URL or IP address I get a time out error. Solution 1: A number of things could be causing this. Try the following troubleshooting steps. • Check if other PCs work. If they do, ensure that your PCs IP settings are correct. If using a Fixed (Static) IP Address, check the Network Mask, Default gateway and DNS as well as the IP Address. • If the PCs are configured correctly, but still not working, check the Wireless ADSL Modem Router. Ensure that it is connected and ON. Connect to it and check its settings. (If you can't connect to it, check the A
105 LAN and power connections.) • Check the Wireless ADSL Modem Router's status screen to see if it is working correctly. Problem 2: Some applications do not run properly when using the Wireless ADSL Modem Router. Solution 2: The Wireless ADSL Modem Router processes the data passing through it, so it is not transparent. For incoming connections, you must use the Virtual Server or Firewall Rules to specify the PC which will receive the incoming traffic. You can also use the DMZ function. This should work with almost every application, but: • It is a security risk, since the firewall is disabled. • Only one (1) PC can use this feature. Wireless Access Problem 1: My PC can't locate the Wireless Access Point. Solution 1: Check the following. • Your PC is set to Infrastructure Mode. (Access Points are always in Infrastructure Mode) • The SSID on your PC and the Wireless Access Point are the same. Remember that the SSID is case-sensitive. So, for example "Workgroup" does NOT match "workgroup". • Both your PC and the Wireless ADSL Modem Router must have the same setting for WEP. The default setting for the Wireless ADSL Mod-em Router is disabled, so your wireless station should also have WEP disabled. • If WEP is enabled on the Wireless ADSL Modem Router, your PC must have WEP enabled, and the key must match. • If the Wireless ADSL Modem Router's Wireless screen is set to Allow Trusted PCs only, then each of your Wireless stations must have been designated as "Trusted", or the Wireless station will be blocked. • To see if radio interference is causing a problem, see if connection is possible when close to the Wireless ADSL Modem Router. Remember that the connection range can be as little as 100 feet in poor environments. Problem 2: Wireless connection speed is very slow. Solution 2: The wireless system will connect at the highest possible speed, depending on the distance and the environment. To obtain the highest possible connec-tion speed, you can experiment with the following: • Wireless ADSL Modem Router location. Try adjusting the location and orientation of the Wireless ADSL Mod-em Router. • Wireless Channel If interference is the problem, changing to another channel may show a
106 marked improvement. • Radio Interference Other devices may be causing interference. You can experiment by switching other devices Off, and see if this helps. Any "noisy" devices should be shielded or relocated. • RF Shielding Your environment may tend to block transmission between the wireless stations. This will mean high access speed is only possible when close to the Wireless ADSL Modem Router.
107 Appendix B About Wireless LANs This Appendix provides some background information about using Wireless LANs (WLANs). Modes Wireless LANs can work in either of two (2) modes: • Ad-hoc • Infrastructure Ad-hoc Mode Ad-hoc mode does not require an Access Point or a wired (Ethernet) LAN. Wireless Sta-tions (e.g. notebook PCs with wireless cards) communicate directly with each other. Infrastructure Mode In Infrastructure Mode, one or more Access Points are used to connect Wireless Stations (e.g. Notebook PCs with wireless cards) to a wired (Ethernet) LAN. The Wireless Stations can then access all LAN resources. Access Points can only function in "Infrastructure" mode, and can communicate only with Wireless Stations which are set to "Infrastructure" mode. BSS/ESS BSS A group of Wireless Stations and a single Access Point, all using the same ID (SSID), form a Basic Service Set (BSS). Using the same SSID is essential. Devices with different SSIDs are unable to communicate with each other. ESS A group of Wireless Stations, and multiple Access Points, all using the same ID (ESSID), form an Extended Service Set (ESS). Different Access Points within an ESS can use different Channels. In fact, to reduce interfe-rence, it is recommended that adjacent Access Points SHOULD use different channels. B
108 As Wireless Stations are physically moved through the area covered by an ESS, they will automatically change to the Access Point which has the least interference or best performance. This capability is called Roaming. (Access Points do not have or require Roaming capabilities.) Channels The Wireless Channel sets the radio frequency used for communication. • Access Points use a fixed Channel. You can select the Channel used. This allows you to choose a Channel which provides the least interference and best performance. In the USA and Canada, 11 channels are available. If using multiple Access Points, it is better if adja-cent Access Points use different Channels to reduce interference. • In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an Access Point. If more than one Access Point can be used, the one with the strongest signal is used. (This can only happen within an ESS.) • If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the same Channel. However, most Wireless stations will still scan all Channels to see if there is an existing "Ad-hoc" group they can join. WEP WEP (Wired Equivalent Privacy) is a standard for encrypting data before it is transmitted. This is desirable because it is impossible to prevent snoopers from receiving any data which is transmitted by your Wireless Stations. But if the data is encrypted, then it is meaningless unless the receiver can decrypt it. If WEP is used, the Wireless Stations and the Access Point must have the same settings for each of the following: WEP Off, 64 Bit, 128 Bit Key For 64 Bit encryption, the Key value must match. For 128 Bit encryption, the Key value must match WEP Authentication Open System or Shared Key. WPA-PSK WPA-PSK is another standard for encrypting data before it is transmitted. This is a later standard than WEP (Wired Equivalent Privacy), and provides greater security for your data. Data is encrypted using a 256Bit key which is automatically generated and changed often. If all your Wireless stations support WPA-PSK, you should use this instead of WEP. If WPA-PSK is used, the Wireless Stations and the Access Point must have the same settings for each of the following: WPA PSK (Pre-shared Key) Enter the same value on every station and the AP. The PSK must be from 8 to 63 characters in length. The 256Bit key used for the actual encryption is derived from this key.
109 Encryption The same encryption method must be used. The most common encryption method is TKIP. Another widely-supported method is AES. WPA2-PSK This is a later version of WPA (WPA-PSK). The major change is the use of AES (Advanced Encryption System) for protecting data. AES is very secure, considered to be unbreakable. The PSK (Pre-shared Key) must be entered on each Wireless station. If WPA2-PSK is used, the Wireless Stations and the Access Point must have the same settings for each of the following: WPA2 PSK (Pre-shared Key) Enter the same value on every station and the AP. The PSK must be from 8 to 63 characters in length. The 256Bit key used for the actual encryption is derived from this key. Encryption The same encryption method must be used. The most common encryption method is TKIP. Another widely-supported method is AES. WPA-802.1x This version of WPA requires a Radius Server on your LAN to provide the client authentica-tion according to the 802.1x standard. Data transmissions are encrypted using the WPA standard. If this option is used: • The Access Point must have a "client login" on the Radius Server. • Each user must have a "user login" on the Radius Server. • Each user's wireless client must support 802.1x and provide the login data when required. All data transmission is encrypted using the WPA standard. Keys are automatically generated, so no key input is required. Wireless LAN Configuration To allow Wireless Stations to use the Access Point, the Wireless Stations and the Access Point must use the same settings, as follows: Mode On client Wireless Stations, the mode must be set to "Infrastructure". (The Access Point is always in "Infrastructure" mode.) SSID (ESSID) Wireless Stations should use the same SSID (ESSID) as the Access Point they wish to connect to. Alternatively, the SSID can be set to "any" or null (blank) to allow connection to any Access Point. Wireless Security The Wireless Stations and the Access Point must use the same settings for Wireless security. (None, WEP, WPA-PSK, WPA2-PSK, WPA-802.1x).
