I've recently been troubleshooting connection problems between PMP450 APs and SMs, and have run into a brick wall without the ability to tap into the communication between them with a tap and WireShark. I've seen several devices with a built-in protocol / packet analyzer to assist with troubleshooting. This feature, in turn, would reduce the number of tickets handled by Cambium support since users would be able to diagnose more of their own problems.
Another solution might be for Cambium to develop an external USB with the ability to capture the 3.6MHz AP-to-SM communication so it could be utilized by WireShark.
After all, it's almost Christmas!
