I've got AP's that previously had no problem communicating but as of the last few days I haven't been able to login to them via SSH (they'll time out) nor ping them... they show up in a cdp neighbor on the 3750 PoE switch they're plugged into, and a show cdp entry will display the proper IP address I'm trying to connect to... but no luck.
I have not changed the firmware on them since the last time I was able to login, has anyone ever seen this happen? If so what do you recommend? I'm trying to avoid having to go out to all of these AP locations as most of them are hidden in ceilings... is there anything I can do from the switch end? Why would they work one day and then all not work the next?
PS - I have other 1231 AP's in different locations running the same firmware and not exhibiting this problem.... it seems to be contained to just certain places, so far 2 of my buildings on campus are showing this problem.
