A method for reducing interference in a first wireless network from a second wireless network, comprising: at an Interfered AP (AP#B), which Interfered AP (AP#B) either itself receives interference or has a station in the Interfered AP's network that receives interference from an Interfering AP(AP#A) or from a station within the Interfering AP's network, the Interfered AP (AP#B) selecting an interference reduction method from a plurality of interference reduction methods, said selecting including: collecting current status information including load information for the current Interfering AP (AP#A), the Interfered AP (AP#B), and a candidate channel, an elapsed time from a prior Channel Switch when a Channel Switch has been previously performed, and an elapsed time from a prior Transmit Power Control, TPC, request when a TPC request has been previously issued; collecting capability information indicating whether the Interfering AP (AP#A) can handle TPC and whether the Interfered AP can collect channel information of neighboring APs; and selecting the interference reduction method based on the collected current status information and capability information, wherein selecting further includes: the Interfered AP (AP#B) switching to the candidate channel when the candidate channel is vacant and the elapsed time from a prior Channel Switch exceeds a first threshold; when no candidate channel is vacant, the Interfered AP monitoring received signal power from the Interfering AP, or the station within the Interfering AP's network, to estimate whether TPC will work well; when it is estimated that TPC will work well and the Interfering AP can handle TPC and the elapsed time from a prior TPC request exceeds a second threshold, the Interfered AP (AP#B) sending a TPC request to the Interfering AP (AP#A) requesting a reduction in transmit power; and when it is estimated that TPC will not work well, the Interfered AP (AP#B) switching to a channel with minimum interference signal power at the Interfered AP (AP#B). collecting current status information including load information for the current Interfering AP (AP#A), the Interfered AP (AP#B), and a candidate channel, an elapsed time from a prior Channel Switch when a Channel Switch has been previously performed, and an elapsed time from a prior Transmit Power Control, TPC, request when a TPC request has been previously issued; collecting capability information indicating whether the Interfering AP (AP#A) can handle TPC and whether the Interfered AP can collect channel information of neighboring APs; and selecting the interference reduction method based on the collected current status information and capability information, wherein selecting further includes: the Interfered AP (AP#B) switching to the candidate channel when the candidate channel is vacant and the elapsed time from a prior Channel Switch exceeds a first threshold; when no candidate channel is vacant, the Interfered AP monitoring received signal power from the Interfering AP, or the station within the Interfering AP's network, to estimate whether TPC will work well; when it is estimated that TPC will work well and the Interfering AP can handle TPC and the elapsed time from a prior TPC request exceeds a second threshold, the Interfered AP (AP#B) sending a TPC request to the Interfering AP (AP#A) requesting a reduction in transmit power; and the Interfered AP (AP#B) switching to the candidate channel when the candidate channel is vacant and the elapsed time from a prior Channel Switch exceeds a first threshold; when no candidate channel is vacant, the Interfered AP monitoring received signal power from the Interfering AP, or the station within the Interfering AP's network, to estimate whether TPC will work well; when it is estimated that TPC will work well and the Interfering AP can handle TPC and the elapsed time from a prior TPC request exceeds a second threshold, the Interfered AP (AP#B) sending a TPC request to the Interfering AP (AP#A) requesting a reduction in transmit power; and when it is estimated that TPC will not work well, the Interfered AP (AP#B) switching to a channel with minimum interference signal power at the Interfered AP (AP#B).
