Methods, devices and systems are provided for diagnosing a wireless module of a device. An exemplary method involves operating a second wireless module of the device to transmit data on a second wireless channel that overlaps, at least in part, a first wireless channel. A measured response associated with the first wireless channel concurrent to the data transmitted on the second wireless channel is obtained from the first wireless module and a remedial action is initiated with respect to the first wireless module based at least in part on the measured response.
