Lion issue with wifi network logins?

I have bound a MacBook Air to our Windows Domain. It binded fine but when i try to switch users or log in it seems to turn off Wi-fi making it impossible to resolve the AD account. How do i set wifi to stay on and connected when logging off or switching users?

We are using WPA2, so i think thats okay... i read that this is a known issue on Lion? (cannot find source again :-/) Seems totally ridiculous if it hasn't been addressed yet.

EDIT: found source...
