A method includes obtaining client information from a set of access points. The client information indicates client devices detected by each access point in the set of access points. In some implementations, the method includes grouping the set of access points into a plurality of access point groups based on the client information. The grouping allows each client device to associate with an access point from at least two different access point groups. The method includes, for a first access point group of the plurality of access point groups, migrating the client devices associated with access points in the first access point group to access points in a second access point group of the plurality of access point groups. In some implementations, the method includes configuring the access points in the first access point group while maintaining configuration of the access points in the second access point group.

Controlling client connectivity during access point upgrades

Systems, methods, and computer-readable media are disclosed for remotely managing and correcting implementation of configuration settings at network devices operating in the network. In one aspect of the present disclosure, a method includes transmitting, by a controller, a request to a network device of the network for a status of operation of the network device with respect at least one configuration setting available at the network device; determining, by the controller, whether the status matches an operation status provided by the at least one configuration setting; and performing, by the controller, a recovery process to adjust the implementation of the at least one configuration setting when the determining determines that the status does not match the operation status.

Remote device status audit and recovery

Previously available network monitoring and management systems fail to provide adequate transmit power control in WiFi networks having multiple neighboring wireless access points. By contrast, various implementations disclosed herein include systems, methods and apparatuses that generate an interference map based at least on co-channel interference reported in a number of neighbor lists, wherein each of the neighbor lists is associated with a respective one of a plurality of compliant wireless access points included in one of a local area network (LAN) and a portion of a virtual LAN (VLAN); and determine a respective transmit power adjustment for each of the plurality of compliant wireless access points included in the interference map based on at least one interference criterion characterizing the interference on each of the plurality of compliant wireless access points included in the interference map and respective neighboring wireless access points.

Jointly managed access point transmit power control

Aspects of the disclosed technology address the problems of calculating and performing channel assignments for access points (APs) in a wireless network. In some aspects, a process for performing channel assignment can include steps for identifying multiple APs in a network, each of the wireless APs being associated with an initial channel assignment, selecting an AP from among the wireless APs in the network, determining a channel quality for the initial channel assignment associated with the AP, and selecting a new channel for the AP based on the channel quality. In some aspects, the process further includes steps for selecting a second AP, determining a channel quality for the initial channel assignment associated with the second AP, and selecting a new channel for the second AP based on the channel quality. Systems and machine-readable media are also provided.
