Windows Vista Networking Center Broken

For some reason detected wireless networks are not shown, it says "Windows cannot find any additional networks". I'm connected to my wireless network because I had it set to automatic but when it comes to when I'm at university I can't connect to any network because the networking center won't show them. I've tried every single driver for the card and neither refreshing the network list or pressing the wifi switch seem to work.

Is anyone having the same problem? It's going to be troublesome for me to reinstall Vista in order to do that.
