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.
O
Update your base station firmware. Firmware is the software that is loaded into
your base station to provide network functions. You can update your base station
firmware by downloading it from the Internet and installing it on your base station. If
you are using a Microsoft base station, make sure that you are using the latest
firmware version.
To update Microsoft base station firmware
1. Double-click the Broadband Network Utility icon on your taskbar to start the
utility.
2. On the Help menu, click Check for Updates Online.
3. If there is a newer version of the firmware available, follow the instructions on
the Web page to download the new software, firmware, or drivers.
