I have the same problem not only with MSM, but with older WESM/RWESM wifi solution. PCM+ v4 couldn't see any access point (we have MSM422). firmware Firmware Ver. 5.7.0.3 or Ver. 5.5.3
with WESM solution are the same problem, PCM couldn't identify any radio ports (we have about 140 radioports and 2 WESm and 2 RWESMs) connected to WESM or RWESM. and also another problem, that in wireless statistics (form 3.20 and 4.0) I couldn't see any information about connected clients (client count in Wireless metrics). Windows wirewall is disabled.
What support sais about this problem? any ideas? i many times installed free (trial) version of PCM, but problems remain the same.
