Adapter Hardware Checks

To actively fix adapter-recognition problems, check the adapter power light. If the Xbox 360 does not recognize that a wireless adapter even exists, make sure that the power light on the wireless adapter is lit up. If not, taking a close look at the connections
should do the trick. Disconnect and then reconnect the adapter cable, and make sure the USB connection is solid before continuing.

Restoring the Xbox 360 wireless network adapter factory defaults is another direct solution for the adapter hardware. Sometimes, new network settings will not be saved by the wireless adapter. If this happens, a restoration to factory default of the network
adapter hardware is necessary. First navigate to the "System" section in the Xbox 360 Dashboard, then click on the option "Restore Default Settings." After you do so, the light on the wireless adapter will fluctuate between red and green, and then stay on
red once the process is complete. Then fill in the new network settings and password and save them to finish the process.
