SYMPTOMS
When a Media Center Extender for Microsoft Windows XP Media Center Edition 2005 detects multiple wireless networks that have the same wireless network name or Service Set Identifier (SSID), you may receive the following error message:

The selected wireless network name (SSID) refers to two or more networks. For example, the same network name is used by both an 802.11a network and an 802.11b network.

When the Extender is connected to one network name assigned to multiple networks, the Extender can encounter network problems. For a reliable experience, assign a unique name to your network.

For more information about changing network names, refer to your wireless network documentation.

The error message may be misleading or incorrect in the following scenarios:  You have a wireless access point that conflicts with another wireless access point that is using the same network name. For example, the other access point may belong to a neighbor. In this scenario, the warning incorrectly states the following:

For example, the same network name is used by both an 802.11a network and an 802.11b network.

In this scenario, an 802.11a network and an 802.11b network may not be in conflict. The conflict may occur between wireless networks in the same band. However, in this scenario, the message correctly states the following:

For a reliable experience, assign a unique name to your network.

For more information about changing network names, refer to your wireless network documentation.

To resolve this issue, you can assign a unique name to your network. You have multiple wireless access points in a roaming configuration. For example, the network names are the same, but you are using different channels. In this scenario, the warning incorrectly states the following:

For a reliable experience, assign a unique name to your network.

In this scenario, you do not have to assign a unique network name to one of the networks. If you use different channels for roaming, you can use multiple wireless access points that have the same network name. In this scenario, you can safely ignore this message and continue.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
