PC authenticating every few minutes

Craig Le-Butt · ‎12-09-2013

Hi

I should know the answer to this, but my head is overloaded.

I have several devices all windows based, authenticating to wlan every few minutes, but they are not moving, they are on the same AP all the time.

But when they do move, they behave the same.

currently running 7.0.240.0 highest we can go.

Any ideas?

cheers

Can you post the show WLAN and also maybe a debug if a client.

Could be many things: client drivers, have you tried removing the wireless profile and creating it again, maybe try a different authentication method, etc.

Check that the session timer on the WLAN advanced tab is not set to a low value. You could just have short session times, which would explain the frequent re-authentications.
