/etc/network/interfaces:

wpa-ssid NETWORK
wpa-psk PASSWORD

/etc/wpa_supplicant/wpa_supplicant.conf:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

so you can keep the wpa conf file as default and only put password and ssid to interfaces. done.

I just downloaded and tried Xbian this week, but I am having major problems trying to get my USB Wi-Fi module to work with my WPA2-PSK network.
It just doesn't want to work, even when trying the helpful tips in this forum and elsewhere.

Right now it fails on "wpa_supplicant: /sbin/wpa_supplicant daemon failed to start" using the quoted setup.

I would like for XBian to adopt a better WPA2 support because the Pi's wi-fi ran fine on the normal NOOBS-installed XBMC version, although considerably slower than XBian does. So what are they doing with their network setup that is missing from XBian?

And how can I fix it myself?
