Did you use xbian-config to configure your network?

Yes, I tried xbian-config to configure wireless network. I must be missing something very obvious.

hi,
Also have an Edimax (non "N") card btw. Got it working in the end.
Installed xbian on the pi last night (1.0Alpha4) had the same problem. (had openelec previously) Didn't want to associate at all. The xbian-config does update the /etc/network/interfaces file but no luck, didnt detect wireless networks nor associated to the WLAN. I don't think it reads or formats the /etc/network/interfaces file correctly. I would suggest taking everything from "allow-hotplug wlan0" out. Save the file and then type it all back, I changed "wireless-power off" to "wireless-power on". Combination of these two seemed to resolve most of the issues.
Other problems I encountered was that if the USB wireless card works the usb mouse does not, and if the ethernet was not plugged in at boot the wireless interface didn't start. Took a few goes but now it is working like a dream. USB mouse works, WLAN0 works (without the ethernet connected). It also associated but got no IP at some point. Static IP worked and after re-doing the /etc/network/interfaces file all was good, even on dhcp.
I have a non "n" wireless lan and it streams 1080p 3D movies over the wireless from a SMB share in the study with no issues. I'm really impressed with XBIAN

I'm having the exact same problems you experienced. Would you be able to provide your config?
