Several troubleshooting steps addressing these issues are listed below, with solutions 
to the most common problems listed first. 
O
Make sure that the rest of your network is functioning correctly. Verify that you 
can access the Internet from other computers on your network. If other computers 
also cannot access the Internet, the problem might be with your base station, 
modem, or Internet service provider (ISP). See the following troubleshooting steps 
for more information. 
If this network does not have an Internet connection, verify that all computers are in 
the same workgroup and can see each other on the network. You can use the 
Broadband Network Utility to view all the computers in your workgroup and check 
your workgroup name. For more information about the Broadband Network Utility, 
see Chapter 4, “Network Activities.”  
If there are problems accessing the Internet or other computers on your network, 
check the cables between your computers and the base station or modem for loose 
or disconnected wires. Check the cables between the base station and the 
broadband modem. Verify that you are using the correct cables, that all cables are 
firmly attached, and that all status lights on the other network devices are 
functioning correctly.  
If you are still having network problems, you should troubleshoot that issue before 
configuring a multiplayer network game. 
O
Check your base station network settings. If other computers on your network are 
also having problems accessing the network and the Internet, you might have 
incorrect base station network settings. Verify that you are using the correct Internet 
settings required by your ISP, and that any wireless settings are correctly configured 
to allow all wireless computers to communicate. 
If you are using a Microsoft base station, you can use the Broadband Network Utility 
and the Base Station Management Tool to check and manually configure your 
network settings. For more information, see Chapter 5, “Network Management.” If 
you are using a base station or router from another manufacturer, see the 
documentation for that device.  
O
Check if your game or application has any special network requirements for 
multiplayer play. Some programs communicate between computers by using 
specific network ports. Most base stations include a firewall that prevents 
unauthorized communication on nearly all ports.  
If your application or game requires special settings on your base station, such as 
forwarding a port for multiplayer play or setting up a virtual DMZ (demilitarized 
zone) to host a game server, you will be able to find this information in the program 
manual or on the software publisher’s Web site. 
For a list of specific programs and the ports necessary to run them, see the Support 
section of the Broadband Networking Web site at www.microsoft.com/hardware.
