Does anyone have a CC connected to an AP?

We have 2 CC's connected to my main router - both setup easily and are working fine. We tried a new CC tonite in my son's room. He's at the other end of the house and we have an access point in that room.

First try around, we got "CC can connect to your router but not the internet". Second time was "You need to disable Client Isolation in your router for CC to work correctly". I've been searching for the last hour and looking thru the AP's admin panel (Asus N10P) and cannot find where to change this setting.

Any advice?
