Channel-Selection

Networks operating without manual WLAN channel planning or ARC 2.0 use automatic channel selection, which evaluates the WLAN channel based on quality criteria such as channel load, interference, and other SSIDs on that channel. If the access points in this type of network are all started at the same time, e.g. after a power failure, all of the access points will assess the channel quality and could all come to the same result. In this case many access points will end up working on the same channel, which in some scenarios may be problematic. Random WLAN channel selection after restarting will ensure that the distribution is as even as possible in larger networks, with little multiple occupancy of any channels.
