Automatic configuration of a wireless distribution system extended network
Methods, systems, and computer readable media may be operable to facilitate the automatic configuration of a network device within a wireless distribution system (WDS) extended network. Upon the boot of a network device such as a network extender, the network device may search for an access point through the transmission and reception of wireless communications. Once an access point is found, the network device may attempt to connect to the access point and may self-configure as either a station or a station operating as an access point. The network device may make the determination whether to operate as an access point based upon one or more network and/or device parameters associated with the identified access point, and may switch between station and station-access point modes based upon the link connecting the network device to the access point.
