Out of curiosity, have you looked to see if any of the affected clients have IPv6 enabled (assuming that it's not an IPv6 network)?

I'm chasing a bunch of reports of wireless users being kicked off the network for no apparent reason. They are able to rejoin right away, but it's happening enough times that they've given up Skyping or other streaming Internet-based applications. The interesting thing is that we are not getting reports of this out in the Academic buildings but it occurred to me that our design is such that those APs join to a pair of WiSM2s while our Residence Hall APs join to a pair of 5508s. On the WiSM2s we have NOT enabled Client Load Balancing, but we did on the 5508s. The rationale we used was that if a wireless client had 2 APs within decent range, Client Load Balancing would help to keep the clients from all associating to one of the two APs. Now I'm wondering if something isn't working quite right and the result is users getting bounced. I have a TAC case open and so far the engineer has come back with upping the "Client user idle timeout" from 5 minutes to 1 hr. I'm not convinced that will help, but also curious if folks have thoughts on that recommendation.
