1. A system for interference detection, the system comprising:
memory; and
one or more processors coupled to the memory and configured to:
receive from one or more access points within a wireless network, for storage in the memory, information indicative of airtime usage of one or more client devices associated with the one or more access points;
determine an amount of total interference for at least one of the access points on a first channel, the total interference including foreign interference and in-network interference;
determine a correlation between the total interference and the airtime usage of the one or more client devices;
determine an amount of the foreign interference or an amount of the in-network interference based on the correlation; and
selectively switch the at least one of the access points from communicating on the first channel to communicating on a second channel based on the determined amount of the foreign interference or the determined amount of the in-network interference.
