WLC526 Wireless Controller Hangs

chris1223 · ‎04-25-2009

I have a new WLC526 installed at a site that seems to hang after about 8 hours of use. I can ping everything else on the network, except for the controller management address. I can also log in the controller via console and do everything except pass traffic across the interface. The controllers management and ap-management IP's are on the same VLAN (default 1) and the wireless users are on VLAN 10 - Usernet.

The controller is connected to a CE520 switch, and using a 1811 router for the gateway.

Any ideas?

The following reasons may cause WLC hang. WLC TSEC driver may hang or crash the device. Certain packets may cause WebAuth services to hang or reload the Device.
