Address Reservation See Configure Reserved IP Addresses on page 81. Configure DHCP By default, the wireless modem router functions as a Dynamic Host Configuration Protocol (DHCP) server, allowing it to assign IP, DNS server, and default gateway addresses to all computers connected to the wireless modem router’s LAN. The assigned default gateway address is the LAN address of the router. IP addresses are assigned to the attached computers from a pool of addresses specified in this screen. Each pool address is tested before it is assigned to avoid duplicate addresses on the LAN. For most applications, the default DHCP and TCP/IP settings of the router are satisfactory. Use Router as DHCP Server If another device on your network will be the DHCP server, or if you will manually configure the network settings of all of your computers, clear the Use Router as DHCP Server check box. Otherwise, leave it selected. Specify the pool of IP addresses to be assigned by setting the starting IP address and ending IP address. These addresses should be part of the same IP address subnet as the router’s LAN IP address. Using the default addressing scheme, you should define a range between 192.168.0.2 and 192.168.0.254, although you might want to save part of the range for devices with fixed addresses. The router delivers the following settings to any LAN device that requests DHCP: • An IP address from the range you have defined • Subnet mask • Gateway IP address, which is the router’s LAN IP address • Primary DNS server, if you entered a primary DNS address in the Basic Settings screen; otherwise, the router’s LAN IP address • Secondary DNS server, if you entered a secondary DNS address in the Basic Settings screen • WINS server, short for Windows Internet Naming Service Server, determines the IP address associated with a particular Windows computer. A WINS server records and reports a list of names and IP addresses of Windows computers on its local network. If you connect to a remote network that contains a WINS server, enter the server’s IP address here. This allows your computers to browse the network using the Network Neighborhood feature of Windows. Configure Reserved IP Addresses When you specify a reserved IP address for a computer on the LAN, that computer will always receives the same IP address each time it accesses the router’s DHCP server. Reserved IP addresses should be assigned to servers that require permanent IP settings. 1. In the LAN Setup screen, click the Add button. 2. In the IP Address field, type the IP address to assign to the computer or server. Choose an IP address from the router’s LAN subnet, such as 192.168.0.x. 3. Type the MAC address of the computer or server. Tip: If the computer is already present on your network, you can copy its MAC address from the Attached Devices screen and paste it here. 4. Click Apply to enter the reserved address into the table. Note: The reserved address will not be assigned until the next time the computer contacts the router’s DHCP server. Reboot the computer or access its IP configuration and force a DHCP release and renew. 1. Select the radio button next to the reserved address that you want to edit or delete. 2. Click Edit or Delete. Set Up Quality of Service (QoS) Quality of Service (QoS) is an advanced feature that can be used to prioritize some types of traffic ahead of others. The modem router can provide QoS prioritization over the wireless link and on the Internet connection. The modem router supports WiFi Multimedia Quality of Service (WMM QoS) to prioritize wireless voice and video traffic over the wireless link. WMM QoS provides prioritization of wireless data packets from different applications based on four access categories: voice, video, best effort, and background. For an application to receive the benefits of WMM QoS, both it and the client running that application need to be WMM enabled. Legacy applications that do not support WMM, and applications that do not require QoS, are assigned to the best effort category, which receives a lower priority than voice and video. Configure QoS for Internet Access 1. From the main menu, under Advanced, select QoS Setup. 2. Click Setup QoS rule. The QoS Priority Rule list displays: 3. To change a rule, select its radio button, and scroll down to the bottom of the screen: 4. To edit a rule, click Edit. To add a custom rule, click Add Priority Rule, and enter the requested information on the screen that displays. 5. Click Apply to save this rule to the QoS Policy list and return to the QoS Setup screen. 6. In the QoS Setup screen, click Apply. Advanced Wireless Settings From the main menu, under the Advanced heading, select Wireless Settings: Restrict Wireless Access to Your Network By default, any wireless computer that is configured with the correct SSID can access your wireless network. For increased security, the wireless modem router provides several ways to restrict wireless access to your network. You can do...
