59 Option Description Hide Access Point Select Hide Access Point to protect the access point from detection by wireless active scans. To check AP status in Windows XP, open Network Connections from the start Menu and select View Available Network Connections. If the access point is hidden, it will not be listed there. To connect a client to a hidden access point, the station must add the access point manually to its wireless configuration. Clients Isolation When enabled, it prevents client PCs from seeing one another in My Network Places or Network Neighborhood. Also, prevents one wireless client communicating with another wireless client. Disable WMM Advertise Stops the router from ‘advertising’ its Wireless Multimedia (WMM) functionality, which provides basic quality of service for time-sensitive applications (e.g. VoIP, Video). Enable Wireless Multicast Forwarding Select the checkbox  to enable this function. SSID [1-32 characters] Sets the wireless network name. SSID stands for Service Set Identifier. All stations must be configured with the correct SSID to access the WLAN. If the SSID does not match, that user will not be granted access. BSSID The BSSID is a 48-bit identity used to identify a particular BSS (Basic Service Set) within an area. In Infrastructure BSS networks, the BSSID is the MAC (Media Access Control) address of the AP (Access Point); and in Independent BSS or ad hoc networks, the BSSID is generated randomly. Country A drop-down menu that permits worldwide and specific national settings. Local regulations limit channel range: US= worldwide, Japan=1-14, Jordan= 10-13, Israel= 1-13 Country RegRev Wireless country code for transmit power limit.

60 5.4.2 Security 2.4GHz The following screen appears when Wireless Security is selected. The options shown here allow you to configure security features of the wireless LAN interface. Please see 6.13.3 for WPS setup instructions. Click Apply/Save to implement new configuration settings. WIRELESS SECURITY Setup requires that the user configure these settings using the Web User Interface (see the table below). Select SSID Select the wireless network name from the drop-down menu. SSID stands for Service Set Identifier. All stations must be configured with the correct SSID to access the WLAN. If the SSID does not match, that client will not be granted access. Network Authentication This option specifies whether a network key is used for authentication to the wireless network. If network authentication is set to Open, then no authentication is provided. Despite this, the identity of the client is still verified. Each authentication type has its own settings. For example, selecting 802.1X authentication will reveal the RADIUS Server IP address, Port and Key fields. WEP Encryption will also be enabled as shown below.
61 The settings for WPA2-PSK authentication are shown next. WEP Encryption This option specifies whether data sent over the network is encrypted. The same network key is used for data encryption and network authentication. Four network keys can be defined although only one can be used at any one time. Use the Current Network Key list box to select the appropriate network key. Security options include authentication and encryption services based on the wired equivalent privacy (WEP) algorithm. WEP is a set of security services used to protect 802.11 networks from unauthorized access, such as eavesdropping; in this case, the capture of wireless network traffic. When data encryption is enabled, secret shared encryption keys are generated and used by the source station and the destination station to alter frame bits, thus avoiding disclosure to eavesdroppers. Under shared key authentication, each wireless station is assumed to have received a secret shared key over a secure channel that is independent from the 802.11 wireless network communications channel.
62 Encryption Strength This drop-down list box will display when WEP Encryption is enabled. The key strength is proportional to the number of binary bits comprising the key. This means that keys with a greater number of bits have a greater degree of security and are considerably more difficult to crack. Encryption strength can be set to either 64-bit or 128-bit. A 64-bit key is equivalent to 5 ASCII characters or 10 hexadecimal numbers. A 128-bit key contains 13 ASCII characters or 26 hexadecimal numbers. Each key contains a 24-bit header (an initiation vector) which enables parallel decoding of multiple streams of encrypted data. Please see 6.13 for MAC Filter, Wireless Bridge and Advanced Wireless features. 5.4.3 Basic 5GHz The Basic option allows you to configure basic features of the wireless LAN interface.

The Restart button is used to detect all the WAN services that are either detected by the auto-detection feature or configured manually by users. The following window will pop up upon clicking the Restart button. Click the OK button to proceed.
74 Auto Detection notice Note: The following description concerning ETHWAN is for multiple LAN port devices only. 1) This feature will automatically detect one WAN service only. If customers require multiple WAN services, manual configuration is required. 2) If a physical ETHWAN port is detected, the Auto Detection for ETHWAN will be fixed on the physical ETHWAN port and cannot be configured for any LAN port; if the physical ETHWAN port is not detected, the Auto Detection for ETHWAN will be configured to the 4th LAN port by default and allows it to be configured for any LAN port as well. 3) For cases in which both the DSL port and ETHWAN port are plugged in at the same time, the DSL WAN will have priority over ETHWAN. For example, the ETHWAN port is plugged in with a WAN service detected automatically and then the DSL port is plugged in and linked up. The Auto Detection feature will clear the WAN service for ETHWAN and re-detect the WAN service for DSL port. 4) If none of the pre-configured services are detected, a Bridge service will be created.

88 Field Description Traffic Class Name Enter a name for the traffic class. Rule Order Last is the only option. Rule Status Disable or enable the rule. Classification Criteria Ingress Interface Select an interface: (i.e. LAN, WAN, local, ETH1, ETH2, ETH3, wl0) Ether Type Set the Ethernet type (e.g. IP, ARP, IPv6). Source MAC Address A packet belongs to SET-1, if a binary-AND of its source MAC address with the Source MAC Mask is equal to the binary-AND of the Source MAC Mask and this field. Source MAC Mask This is the mask used to decide how many bits are checked in Source MAC Address. Destination MAC Address A packet belongs to SET-1 then the result that the Destination MAC Address of its header binary-AND to the Destination MAC Mask must equal to the result that this field binary-AND to the Destination MAC Mask. Destination MAC Mask This is the mask used to decide how many bits are checked in the Destination MAC Address. Classification Results Specify Egress Interface Choose the egress interface from the available list. Specify Egress Queue Choose the egress queue from the list of available for the specified egress interface. Mark Differentiated Service Code Point The selected Code Point gives the corresponding priority to packets that satisfy the rule. Mark 802.1p Priority Select between 0-7. - Class non-vlan packets egress to a non-vlan interface will be tagged with VID 0 and the class rule p-bits. - Class vlan packets egress to a non-vlan interface will have the packet p-bits re-marked by the class rule p-bits. No additional vlan tag is added. - Class non-vlan packets egress to a vlan interface will be tagged with the interface VID and the class rule p-bits. - Class vlan packets egress to a vlan interface will be additionally tagged with the packet VID, and the class rule p-bits. Set Rate Limit The data transmission rate limit in kbps.
89 6.3.3 QoS Port Shaping QoS port shaping supports traffic shaping of the Ethernet interface.Input the shaping rate and burst size to enforce QoS rule on each interface.

100 6.8 Interface Grouping Interface Grouping supports multiple ports to PVC and bridging groups. Each group performs as an independent network. To use this feature, you must create mapping groups with appropriate LAN and WAN interfaces using the Add button. The Remove button removes mapping groups, returning the ungrouped interfaces to the Default group. Only the default group has an IP interface. To add an Interface Group, click the Add button. The following screen will appear. It lists the available and grouped interfaces. Follow the instructions shown onscreen.
101 Automatically Add Clients With Following DHCP Vendor IDs: Add support to automatically map LAN interfaces to PVC's using DHCP vendor ID (option 60). The local DHCP server will decline and send the requests to a remote DHCP server by mapping the appropriate LAN interface. This will be turned on when Interface Grouping is enabled. For example, imagine there are 4 PVCs (0/33, 0/36, 0/37, 0/38). VPI/VCI=0/33 is for PPPoE while the other PVCs are for IP set-top box (video). The LAN interfaces are ETH1, ETH2, ETH3, and ETH4. The Interface Grouping configuration will be: 1. Default: ETH1, ETH2, ETH3, and ETH4. 2. Video: nas_0_36, nas_0_37, and nas_0_38. The DHCP vendor ID is "Video".
102 If the onboard DHCP server is running on "Default" and the remote DHCP server is running on PVC 0/36 (i.e. for set-top box use only). LAN side clients can get IP addresses from the CPE's DHCP server and access the Internet via PPPoE (0/33). If a set-top box is connected to ETH1 and sends a DHCP request with vendor ID "Video", the local DHCP server will forward this request to the remote DHCP server. The Interface Grouping configuration will automatically change to the following: 1. Default: ETH2, ETH3, and ETH4 2. Video: nas_0_36, nas_0_37, nas_0_38, and ETH1.
