If its an authentication issue, then you can enable client exclusion on the WLAN also. 3 failures will automatically put them in the exculsion list. Not that I like pgrading, but the latest versions of 7.0.x are pretty good, but you need to make sure your AP's support that code. 6.x is pretty old.
Well.... is there any client issues? If not, then maybe its a bug on that code. You have to look into it more and see as a corrupted driver on the client end can be causing the issue or maybe its a newer device that acts differently. Try upgrading and see if it goes away or else you need to figure out what client that is and see if you can figure out the issue.
