A federation of wireless access points (APs) enables superior network connectivity when compared to a single wireless AP. This disclosure describes secure formation of an AP federation. An AP discovers the presence of a neighboring AP by detection of beacons and probe responses transmitted by the neighboring AP or by explicit transmission of a probe request. A known credential is presented by the AP to the neighboring AP to establish a connection and obtain an IP address. A federation service discovery message is transmitted specifying a port number and the IP address associated with the neighboring AP. A response message is transmitted by the neighboring AP that includes a base MAC address associated with the neighboring AP, a federation service IP address associated with the base MAC address, and the port number. Federation service discovery messages are exchanged between the APs that denote the access points as trusted members of the federation.
