Trust Domain issues over Wifi

[tombstone1]

I have a wireless network that is using a 5508 WLC (running 8.3.122.0), and AIR-LAP1142N-A-K9. My users are having trust domain relationship issues with their laptops when connected to WiFi. I have isolated this problem to WiFi by connecting the Laptops directly with a LAN cable and they do not have this issue. I think this has something to do with AP isolation but am not sure. Does anyone have any clue what could be causing this?

This may sound weird but it was the TCP adjust MSS option on the new APs. Unchecking it seems to have fixed the issue.

Sounds like a software bug or driver issue in the client.

I would agree except it happens on multiple clients with different wifi cards.
