Upgrading wireless infrastructure through scheduling

A method comprising:

• determining best nearest Access Points (APs) for client devices associated with a first AP to roam to;
• increasing power of signal levels from the best nearest APs;
• and
• upgrading software on the first AP in response to the client devices associated with the first AP roaming to the best nearest APs in response to increasing power of the signal levels from the best nearest APs.

A method comprising:

• determining a Target Wake Time (TWT) for each client device associated with an Access Point (AP);
• processing, based on TWT sensitivity, ones of the client devices associated with the AP having TWTs less than a reboot time of the AP;
• and
• scheduling a software upgrade of the AP during a scheduled sleep time of client devices associated with the AP.

A method comprising:

• notifying, by a controller, a plurality of Access Points (APs) that the controller is scheduled to be down;
• continuing, by the plurality of APs, to server client devices during a scheduled down time of the controller;
• and
• designating a one of the plurality of APs to function as the controller for the plurality of APs during the scheduled down time of the controller.
