Is there any way (debug, trap,...) the AP can send/show if the external antenna is broken or disconnected? We have lots of AP's installed in a place where sometimes the external antennas can be broken, and I'd like to know if there is a way to know it at the time it happens.
Baseline the working system and watch for a major drop in the signal level.
You could probably write a Perl script that would telnet the AP (using Net::Telnet, for example) and track the RSSI (Radio Signal Strength Indication) from the AP- this is receive only, but if the majority of hosts are running at minimum marginal levels you can probably track & chart it.
You can put in something like a "Bird" meter (measures power and (I think) SWR) - if you have a screwed-up antenna, the SWR is gonna go up significantly. There will be losses associated with an in-line system.

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.
