3. In the Network Address Server Settings (DHCP) section (see Figure 3.22), click Enable. 84 Networking with Microsoft ® Windows Vista ™ 3 FIGURE 3.22 On most Linksys routers, use the Setup tab’s Basic Setup subtab to enable the DHCP server. 4. Use the Starting IP Address text box to specify the first address in the range of IP addresses that the server can assign. 5. Use the Maximum Number of DHCP Users text box to limit the num- ber of DHCP leases that the server can assign. This isn’t important on a small network, and the default value of 50 is more than enough. 6. Use the Client Lease Time text box to specify the time, in minutes, that each client can keep its IP address. The default value of 0—which cor- responds to one day—is fine for most small networks. 7. At the bottom of the page, click Save Settings. The router reports that the Settings are successful. 8. Click Continue. Netgear On most Netgear routers, here are the steps to follow to enable the DHCP server: 1. Under Advanced, click the LAN IP Setup link. The LAN IP Setup page appears, as shown in Figure 3.23. 2. Click to activate the Use Router as DHCP Server check box. 3. Use the Starting IP Address text box to specify the first address in the range of IP addresses that the server can assign. You can see a list of DHCP clients on most Linksys routers by clicking the Status tab, clicking the Local Network subtab, and then click- ing DHCP Clients Table. note Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark. FIGURE 3.23 On most Netgear routers, use the LAN IP Setup page to enable the DHCP server. Modifying Wireless Settings If your router includes a wireless access point (AP), you need to configure a few settings before making wireless connections to the AP. On most routers, you can configure the following settings: Network name This is the name of your wireless network, which is often called the service set identifier, or SSID. All routers come with a default SSID, usually some variation on the man- ufacturer’s name, such as linksys or belkin54g. Changing the SSID to something memorable will help you to identify your network in Vista’s list of available wireless networks, and it will avoid confusion with other nearby wireless networks that still use the default name. CHAPTER 3 Configuring Your Router 85 3 4. Use the Ending IP Address text box to specify the last address in the range of IP addresses that the server can assign. 5. Click Apply. You can see the list of DHCP clients on most Netgear routers by clicking the LAN IP Setup link under Advanced and then scrolling to the Address Reservation section. note Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark. SSID broadcasting This setting determines whether your router broadcasts the SSID, which makes the wireless network visible in Windows Vista’s list of available networks. It’s best to enable SSID broadcasting when you first make your con- nections to the wireless network. However, Windows Vista can remember the networks you’ve connected to in the past, so you can later disable SSID broadcasting as a security measure. (Although see Chapter 15, “Implementing Wireless Security,” for some important information on just how secure this tactic really is.) ➔ For more information on disabling SSID broadcasting, see “Disabling Network SSID Broad- casting,” p. 347. Wireless mode This tells the router which Wi-Fi standard—802.11a, 802.11b, 802.11g, or 802.11b—to implement. If your router supports more than one standard, you can con- figure the router to use multiple standards (for exam- ple, both 802.11b and 802.11g; this is often called mixed mode) or just a single standard. For example, if all your wireless devices use 802.11g, you should con- figure the router to use only that standard. Wireless channel This setting determines the radio frequency (RF) band that the wireless AP uses to transmit and receive signals. For successful wireless networking connections, all your net- working devices must use the same channel. The next few sections show you how to configure these wireless settings in var- ious routers. Belkin Follow these steps to configure wireless settings on most Belkin routers: 1. Under Wireless, click the Channel and SSID link to display the Channel and SSID page, shown in Figure 3.24. 2. Use the SSID text box to specify the network name you want to use. 3. Use the ESSID Broadcast group to click either Enable or Disable. 4. Use the Wireless Mode list to select a wireless mode. 5. Use the Wireless Channel list to select a frequency (or click Auto to let the router select the correct frequency automatically). 6. Click Apply Changes. 86 Networking with Microsoft ® Windows Vista ™ 3 Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark.

Use the Wireless Network Name text box to specify the network name you want to use. 5. If you want the router to automatically select the correct channel for your network, leave the Enable Auto Channel Scan check box acti- vated; otherwise, deactivate Enable Auto Channel Scan, and then use the Wireless Channel list to select a frequency. 6. If you want the router to only use 802.11g, click to activate the 802.11g Only Mode check box. 7. To prevent the router from broadcasting the network name, click to activate the Enable Hidden Wireless check box. 8. Click Save Settings. The router restarts to put the new settings into effect.

Testing Your Router’s Capabilities Microsoft offers a useful Internet Explorer add-on called the Internet Connectivity Evaluation Tool that examines your router and determines whether it supports several advanced features that Windows Vista can take advantage of to maximize Internet and network performance. The tests performed by the Internet Connectivity Evaluation Tool include the following: ■ Network Address Translation Type. This test determines the NAT sup- port provided by your router. Specifically, the tool checks to see whether your router supports cone NAT or symmetric NAT. Cone NAT means that when a client with a specific internal address uses a port, all exter- nal hosts can communicate with the client by sending data through that port to the external address. Symmetric NAT means that when a client with a specific internal address uses a port to communicate with an external host, NAT creates a unique mapping for the internal address and port, and only that external host can use the mapping. If the client uses the same port to communicate with a different external CHAPTER 3 Configuring Your Router 93 3 Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark.
