5HARDWARE CONNECTION Note: Before you starting hardware connection, you are advised to find an appropriate location to place the Access Point. Usually, the best place for the Access Point is at the center of your wireless network, with line of straight to all your wireless stations. Also, remember to adjust the antenna; usually the higher the antenna is placed, the better will be the performance. 1. Connect to your local area network: connect an Ethernet cable to the Ethernet port of this Wireless Access Point, and the other end to a hub, switch, router, or another wireless access point. 2. Power on the device: connect the included AC power adapter to the Wireless Access Point’s power port and the other end to a wall outlet. 3. Configure your PC: Make sure your local PC(s) has wireless network adapter installed.

6ABOUT THE OPERATION MODES This device provides four operational applications with Access Point, Bridge, Client (Ad-hoc) and Client (Infrastructure) modes, which are mutually exclusive. This device is shipped with configuration that is functional right out of the box. If you want to change the settings in order to perform more advanced configuration or even change the mode of operation, you can use the web-based utility provided by the manufacturer as described in the following sections. Access Point Mode When acting as an access point, this device connects all the stations (PC/notebook with wireless network adapter) to a wired network. All stations can have the Internet access if only the Access Point has the Internet connection. See the sample application below. To set the operation mode to Access Point, please go to “Wireless JBasic Settings”, in the “Mode” field click the down arrow b to select AP mode.

7Bridge Mode Refer to the illustration below. While acting as Bridges, AP1 (with Station 1 being associated to) and AP2 (with Station 2 being associated) can communicate with each other through wireless interface (with WDS). Thus Station 1 can communicate with Station 2 and both Station 1 and Station 2 are able to access the Internet if only AP1 or AP2 has the Internet connection. To set the operation mode to Bridge, please go to “Wireless JBasic Settings”, in the “Mode” field click the down arrow b to select AP mode. And go to “Wireless JWDS Settings” to enable WDS. Note: To act as Bridge, both AP1 and AP2 must have WDS enabled and add each other as its WDS Access Point. (e.g. Add AP2’s MAC address to AP1’s “WDS AP List” and vice versa)

8Client Mode (Infrastructure) If set to Client (Infrastructure) mode, this device can work like a wireless station when it’s connected to a computer so that the computer can send packets from wired end to wireless interface. Refer to the illustration below. This station (AP1 plus the connected computer 1) can associate to another Access Point (AP2), and then can have the Internet access if the other Access Point (AP2) has the Internet connection. To set the operation mode to Client (Infrastructure), please go to “Wireless JBasic Settings”, in the “Mode” field click the down arrow b to select Client mode, and then select “Network Type” as “Infrastructure”.

9Client Mode (Ad-hoc) If set to the Client (Ad-hoc) mode, this device can work like a wireless station when it is connected to a computer so that the computer can send packets from wired end to wireless interface. You can share files and printers between wireless stations (PC and laptop with wireless network adapter installed). See the sample application below. To set the operation mode to Client (Ad-hoc), please go to “Wireless JBasic Settings”, in the “Mode” field click the down arrow b to select Client mode, and then select Network Type as “Ad-hoc”.

10CONFIGURATION Login 1. Start your computer. Connect an Ethernet cable between your computer and the Wireless Access Point. 2. Make sure your wired station is set to the same subnet as the Wireless Access Point, i.e. 192.168.100.12. 3. Start your WEB browser. In the Address box, enter the following: HTTP://192.168.100.252 The configuration menu is divided into four categories: Status, Wireless, TCP/IP, and Other settings. Click on the desired setup item to expand the page in the main navigation pane. The setup pages covered in this utility are described below.

11Status In this screen, you can see the current settings and status of this Access Point. You can change settings by selecting specific tab described in below. System System Alias Name You can assign a unique name to this Access Point. The alias name is especially important for identification when there are more than one Access Point is applied in a network. Uptime The time period since the device was up. Firmware Version The current version of the firmware installed in this device. Wireless Configuration Wireless Mode There are four modes supported, Access Point, Client (Ad-hoc and Infrastructure), and Bridge. The default mode is Access Point. If you want to change to bridge mode, please go to Wireless/WDS Setting to enable the WDS function. SSID The SSID differentiates one WLAN from another, therefore, all access points and all devices attempting to connect to a specific

12WLAN must use the same SSID. It is case-sensitive and must not exceed 32 characters. A device will not be permitted to join the BSS unless it can provide the unique SSID. An SSID is also referred to as a network name because essentially it is a name that identifies a wireless network. Channel Number: The number of channels supported depends on the region of this Access Point. All stations communicating with the Access Point must use the same channel. Encryption WEP Encryption (Wired Equivalent Privacy) is set to Disabled by default. When WEP is enabled, data packet is encrypted before being transmitted. The WEP prevents data packets from being eavesdropped by unrelated people. By using WEP data encryption, there may be a significant degradation of the data throughput on the wireless link. Associated Clients Displays the total number of clients associated to this AP. You can have up to 64 clients to associate to this Access Point. BSSID BSSID displays the ID of current BSS, which uniquely identifies each BSS. In AP mode, this value is the MAC address of this Access Point. TCP/IP Configuration IP Protocol Display the method to get the IP of this AP, which could be obtained by Fixed-IP or DHCP-client. br0 IP Address Current IP address for this Access Point br0 Subnet Mask Current Subnet mask for this Access Point br0 Default Gateway Default Gateway for this Access Point br0 MAC Address The MAC Address for this Access Point System Log This page display log events with time when events happened, log events’ types, log sources and the description for events themselves. System manager can use the system log to trace when problems occur.

13 Statistics The Statistics table shows the packets sent/received over wireless and ethernet LAN respectively. Active Clients This page display wireless stations that are associated to this Access Point, with information of their MAC addresses, transmitted/received packets, transmitting rate, power saving mode, and expired time. Press Refresh to get the latest information.

15Wireless Basic Settings This page includes all primary and major parameters. Any parameter change will cause the device to reboot for the new settings to take effect. Alias Name: Maximum 32 characters alpha-numeric You can assign a unique name to this Access Point. The alias name is especially useful for identification when there are more than one Access Point is applied in a network.  Disable Wireless LAN Interface: Check the box to disable the Wireless LAN Interface, by so doing, you won’t be able to make wireless connection with this Access Point in the network you are located. In other words, this device will not be visible by any wireless station. Mode: This Wireless Access Point can support four modes AP, Client (Ad-hoc), Client (Infrastructure), and Bridge. The default is set to AP mode. In the “Mode” field Click the pull down arrow d then you can change it to Client mode. To change to Bridge mode, you will have to set to AP mode, and go to Wireless/WDS setting to enable WDS.

16Network Type: When in Client mode, you can select between Ad-Hoc and Infrastructure. SSID: The SSID differentiates one WLAN from another, therefore, all access points and all devices attempting to connect to a specific WLAN must use the same SSID. It is case-sensitive and must not exceed 32 characters. A device will not be permitted to join the BSS unless it can provide the unique SSID. An SSID is also referred to as a network name because essentially it is a name that identifies a wireless network. Channel Number: Allow user to set the channel manually or automatically. If set channel manually, just select the channel you want to specify. If “Auto” is selected, user can set the channel range to have Wireless Access Point automatically survey and choose the channel with best situation for communication. The number of channels supported depends on the region of this Access Point. All stations communicating with the Access Point must use the same channel. From Channel:  To Channel:  When select “Auto” in “Channel Number, you have to set a range of channels for the Access Point to automatically survey and choose the channel for optimal performance. Allowed Clients Enter a number ranging from 1 to 64. Apply Change Press to save the new settings on the screen. Reset Press to discard the data you have entered since last time you press Apply Change. Advanced Settings It is not recommended that settings in this page to be changed unless advanced users want to change to meet their wireless environment for optimal performance

17 Authentication Type To provide a certain level of security, the IEEE 802.11 standard has defined two types of authentication methods, Open System and Shared Key. With Open System authentication, a wireless PC can join any network and receive any messages that are not encrypted. With Shared Key authentication, only those PCs that possess the correct authentication key can join the network. By default, IEEE 802.11 wireless devices operate in an Open System network. Wired Equivalent Privacy (WEP) data encryption is used when the wireless devices are configured to operate in Shared Key authentication mode. If the Access Point is using "Open Authentication”, then the wireless adapter will need to be set to the same authentication mode. Shared Authentication is used when both the sender and the recipient share a secret key. Select Auto for the network adapter to select the Authentication mode automatically depending on the Access Point Authentication mode.

18Fragment Threshold Fragmentation mechanism is used for improving the efficiency when high traffic flows along in the wireless network. If your 802.11g Wireless LAN PC Card often transmit large files in wireless network, you can enter new Fragment Threshold value to split the packet. The value can be set from 256 to 2346. The default value is 2346. RTS Threshold RTS Threshold is a mechanism implemented to prevent the “Hidden Node” problem. “Hidden Node” is a situation in which two stations are within range of the same Access Point, but are not within range of each other. Therefore, they are hidden nodes for each other. When a station starts data transmission with the Access Point, it might not notice that the other station is already using the wireless medium. When these two stations send data at the same time, they might collide when arriving simultaneously at the Access Point. The collision will most certainly result in a loss of messages for both stations. Thus, the RTS Threshold mechanism provides a solution to prevent data collisions. When you enable RTS Threshold on a suspect “hidden station”, this station and its Access Point will use a Request to Send (RTS). The station will send an RTS to the Access Point, informing that it is going to transmit the data. Upon receipt, the Access Point will respond with a CTS message to all station within its range to notify all other stations to defer transmission. It will also confirm the requestor station that the Access Point has reserved it for the time-frame of the requested transmission. If the “Hidden Node” problem is an issue, please specify the packet size. The RTS mechanism will be activated if the data size exceeds the value you set.. The default value is 2347. Warning: Enabling RTS Threshold will cause redundant network overhead that could negatively affect the throughput performance instead of providing a remedy. This value should remain at its default setting of 2347. Should you encounter inconsistent data flow, only minor modifications of this value are recommended. Beacon Interval Beacon Interval is the amount of time between beacon transmissions. Before a station enters power save mode, the station needs the beacon interval to know when to wake up to receive the beacon (and learn whether there are buffered frames at the access point). DTIM Period DTIM stands for Delivery Traffic Indication Message. A DTIM is a countdown field informing clients of the next

19window for listening to broadcast and multicast messages. When the access point has buffered broadcast or multicast message for associated clients, it sends the next DTIM with a DTIM Period value. Access point clients hear and awaken to receive the broadcast and multicast messages. The default DTIM period is ‘3’. Data Rate By default, the unit adaptively selects the highest possible rate for transmission. Select the basic rates to be used among the following options: Auto, 1, 2, 5.5, or 11 Mbps. For most networks the default setting is Auto which is the best choice. When Auto is enabled the transmission rate will select the optimal rate. If obstacles or interference are present, the system will automatically fall back to a lower rate. Preamble Type A preamble is a signal used in wireless environment to synchronize the transmitting timing including Synchronization and Start frame delimiter. In a "noisy" network environment, the Preamble Type should be set to Long Preamble. The Short Preamble is intended for applications where minimum overhead and maximum performance is desired. If in a "noisy" network environment, the performance will be decreased. Broadcast SSID Select enabled to allow all the wireless stations to detect the SSID of this Access Point. IAPP To enable IAPP means that Access Points will communicate across the backbone network, so that mobile stations can roam between them. Apply Change Press to save the new settings on the screen. Reset Press to discard the data you have entered since last time you press Apply Change.

20Security Here you can configure the security of your wireless network. Selecting different method will enable you to have different level of security. Please note that by using any encryption, by which data packet is encrypted before transmission to prevent data packets from being eavesdropped by unrelated people, there may be a significant degradation of the data throughput on the wireless link. Encryption : None ( Encryption is set to None by default. )  If None is selected, you can still select to Use 802.1x Authentication and Enable MAC Authentication.  To Enable MAC Authentication means to use client MAC address for authentication with RAIDUS server  If both Use 802.1x Authentication and Enable MAC Authentication are selected, the RADIUS Server will check MAC Authentication first; if the MAC Authentication passes, the 802.1x Authentication will be skipped.
