Symptom
AP 2802 suddenly drops in transmission power level when having WGB connected.
WGB can be 2700 or 3700 series AP.
- We can see a huge LAP RSSI drop for beacons, RTS/CTS and possibly other management frames
- This power level drop happened for around 2 seconds and then the AP recovers on it's own
We were able to identify this behavior since the customer has a WGB connected to the 2802 AP. WGB keeps disconnecting when this power level drop happens:

*WGB, LAP, and sniffer AP were stationary when collecting those logs
Workaround
None atm. AP recovers after 1-2 secs and WGB reconnects.
