CAUSE

The Xbox 360 Wireless Networking Adapter supports the following wireless protocols:

802.11b: This standard has a 2.4-gigahertz (GHz) frequency that provides up to 11-megabits-per-second (Mbps) throughput.
802.11g: This standard has a 2.4-GHz frequency that provides up to 54-Mbps throughput.
802.11a: This standard has a 5.0-GHz frequency that provides up to 54-Mbps throughput.

Note The 802.11n (or "draft N"), wireless protocol is not currently supported by the Xbox Wireless Adapter.

THINGS TO TRY

Many 802.11n routers can be configured to use an 802.11b, 802.11g, and 802.11a "mixed" mode. The Xbox 360 Wireless Adapter should be able to connect to a router that is configured in this manner. See your router's documentation for more information about how to configure the router in this manner.
Use a different router that does support the 802.11b, 802.11g, or 802.11a protocol. These standards all work with the Xbox Wireless Network Adapter.
