Laptop can't see any wireless network, but still connects to one
I recently moved and had to re-setup a new wireless network at home. Unfortunately, my laptop can't seem to see any wireless network (the available wireless network list is always empty). There's a non protected wireless network near my home, and even though it doesn't appear in the list, it automatically connects to it. Using my girlfriend's laptop, I can tell that there is about 10 networks in the area (including mine). My laptop doesn't see any of them. I must have triggered something because I never had any problem of the kind before.
