Everything had been running fine for a month or so... Just recently, I began receiving critical messages from the WLC saying that the AP went down... In the logs, I find the following for everytime I received such an e-mail:

The AP is coming into a 3750 switch which, when it went down, the port was flashing orange... The AP did reset itself and come back up... Is this a hardware issue, cabling issue or configuration??? It is now up and running again with no issues (for now)...
