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.

If you are using a wireless connection, check for range and interference issues.
You might be out of range of the wireless base station, gateway, or router. Position
the computer with the wireless adapter in the same room as your base station and
try connecting again. If you can connect to the wireless network and run
applications and games without a problem, you might have been previously out
of range.
Another cause of problems is that signals transmitted between the base station and
a wireless adapter can be affected by interference from other wireless devices—
including 2.4-GHz cordless phones, microwave ovens, and neighboring wireless
networks. Move the other devices as needed, and refrain from using them while you
are using the network. To minimize interference from another wireless network, try
changing the wireless channel. For information about how to change your wireless
settings, see Broadband Network Utility Help.
O
Check for duplicate NAT features, DHCP servers, or firewalls.
Network Address
Translation (NAT) and Dynamic Host Configuration Protocol (DHCP) are security
features of the Microsoft base station and some other devices. If two devices, such
as a base station and modem, are running NAT and/or DHCP servers at the same
time, the devices can interfere with each other and cause intermittent failures. If
you are running a Microsoft base station, for example, its firewall and NAT features
could conflict with other network hardware and software. Verify that you have
disabled NAT functionality and DHCP servers on other devices in your network. To
determine if a device has one of these features, check the documentation for that
device. Some other common network devices that could contain these features
include routers, broadband modems, or wireless access points.
Software firewalls can also cause conflicts. Make sure that you turn off any
personal firewall software, such as Internet Connection Firewall, when trying to run
a game.
