Have a Cisco WLC 4400, that keeps dropping off our business network. The light keeps going out where the module connects to the WLC from the network via a network cable I.E. WLC Module>Ethernet cable> switch.
I have too regularly replugh the module back into the controller for the wireless to kick back in and the light come on. I have tried another cable and now think it maybe the module. Someone suggested re-configuring the WLC to the 2nd port to see if the issue confirms it is the module or just port 1. Good idea.
How would I do this ?
