Adaptive preferred scan channels in wireless networks
Disclosed are systems, apparatuses, methods, and computer-readable media for adaptive preferred scan channels in wireless networks. A method includes: retrieving previous client device information connected to at least one access point (AP), analyzing the previous client device information for at least one property associated with wireless network usage of the at least one AP; and determining whether to configure preferred scan channels with additional channels based on the at least one property associated with the wireless network. Adding preferred scan channels to the default configuration can benefit wireless network performance.
