I have an Aironet AP4800 in diversity mode with one antenna port connected
to the usual included antenna and the other connected to a 1W AGC amp. I've
noticed that if power is removed from the amp for more than a few minutes
and then restored, the AP4800 no longer sends beacons through the associated
antenna port. The port isn't disabled totally since it will transmit (it seems)
in response to some received packets. Anything on the AP4800 that restarts
the radio restores normal operation. It can't be as simple as the AP4800
giving up on the port after a while not seeing packets since this would happen
anyway when there are no clients. It's also hard to believe that the Hyperlink
amp when off presents such a different impedance as to cause the radio to get
upset (or even that the radio is checking reflections). No errors are logged.
Thoughts?
