Strange Wism and AP problem

We've just started using NAC to register our students and found a strange thing occuring. If a user is near 2 AP's and registers his laptop on one of them, when the reg system deauth's him to switch him to a 'safe' vlan, the laptop switches to another AP and somehow gets lost in the controller system and is again forced to register.

Not sure if that is explained well. But I'm seeing a wireless client vascillate between AP's and well Vlan's. Has anyone experienced this? Anyone know if there is some way for the Wism's to actually know that a client is reg'd on one controller and allow them to continue with the process of vlan changing?

Re: Strange Wism and AP problem

Verify that your mobility group is configured correctly. If you have multiple vlans and are using a single ssid, then you will have to look at using AP Groups. I have a client using NAC for the internal wireless users and they have no issues. So just recheck you configuration.
