Wireless problem

[davholla]

I have a new install of Mint (13 I think).
Wireless did work but now it doesn't although it still does for Windows Vista.
It is now away from the router so I can't test wired again.

Any ideas?

cat /etc/network/interfaces
auto lo
iface lo inet loopback

i believe every interface should be mentioned in /etc/network/interfaces
