Abstract: Techniques for wireless communication are disclosed. These techniques include determining that a first wireless access point (AP) has a failure to connect to a controller. The techniques further include identifying one or more neighbor APs, for the first AP, as candidate rescue APs, selecting a rescue AP, from among the candidate rescue APs, and establishing a secure connection from the first AP to the rescue AP. The techniques further includes transmitting diagnostic data from the first AP to the controller using the secure connection from the first AP to the rescue AP. The diagnostic data relates to the failure to connect from the first AP to the controller, and the controller is configured to use the diagnostic data to assist in establishing a connection from the first AP to the controller that bypasses the rescue AP

Abstract: Techniques for assigning APs to wireless network controllers are described. One or more RF constellations for a plurality of APs in a wireless network are generated. The RF constellations are organized based on estimated RF distances among the plurality of APs. The plurality of APs are clustered into a plurality of groups of one or more APs, based on the RF constellations and the estimated RF distances. Each group, of the plurality of groups, is assigned to a wireless network controller.

Abstract: Techniques for dynamic bandwidth expansion are provided. A first set of channel quality metrics is collected, by an access point (AP) communicating using a first bandwidth, for an expanded bandwidth beyond the first bandwidth. A second set of channel quality metrics for the expanded bandwidth is received from one or more stations. An available portion of the expanded bandwidth is then determined based on the first and second sets of channel quality metrics. Communication with the one or more stations is initiated using the available portion of the expanded bandwidth.
