Intermittent Wireless Authentication Failures 877W - Advice/Help needed

Hi All,

Wondering if anybody can offer advice on an 877W where the Wireless authentication stops after 1-2 days of the router being powered up and operational.

All devices are able to authenticate and connect to the Wireless Interface, until maybe 1-2 days after the router has been operational.

After this point all devices fail to connect to the AP.

The only way I have been able to resolve this so far is by rebooting the router. I have attempted to shut/no shut the dot11 interface, but no joy.

When the Router enters this blocked state, the radio still appears to transmit as I can view the SSID under available networks. Trying to connect to it results in a failure, as if it is an authentication issue.

This is a new box. If anybody could give my config a once over and suggest anything, or perhaps offer some debug advice this would be great.

I have tried setting the Router from Channel 11 to 1 in case of clash but the problem still exists.

I have attached my config along with sh ver.

Many Thanks,

Kevin
