A method for detecting interferences in wireless networks is disclosed. A salient idea is to use a first access point for detecting an interference disturbing a wireless device associated with a second access point, wherein the device at the origin of the interference is in the range of the first access point, but not in the range of the second access point. Leveraging on the difference of coverage between different wireless networking technologies, the first access point is capable of detecting both a data traffic of a second access point and a short-range interfering device in a same frequency channel.
