An apparatus and method are disclosed to communicate, from a first device to a wireless device, information by which the wireless device may identify an access point as a potential network device. The information is encoded in a packet stream by the first device, and wirelessly communicated from the access point to the wireless device. The information may be encoded by varying a packet characteristic, such as packet length, that is preserved even if the packets are encoded by the access point. The information may include a beacon, a SSID and/or a key.
