Abstract: Techniques are presented for discovering a previously configured network device. In one embodiment, a basic service set identification (BSSID) that uniquely identifies a network device (i.e., a router) is saved when the network device or a client device is configured. The stored BSSID indicates that the network device has previously been configured. After the network device is reset—i.e., one or more user-configurable settings return to their default settings—a client device may execute a setup application to reconfigure the network device. The setup application may compare the BSSID being broadcasted by the network device with the BSSID stored in the memory. If the BSSIDs match, the setup application may automatically select the network device without user input. Because the network device was previously configured, the setup application assumes that the user is attempting to reconfigure the network device after it has been reset.

When a paging message received through a single antenna decodes with an incorrect error checking code, the mobile wireless devices enables receive diversity through multiple antennas for subsequent decoding. The mobile wireless device switches between single antenna reception and multiple antenna reception based on tracking multiple consecutive error checking code failures and successes.
