Wireless Networks LOST!!! Urgent Help

[coolguy1]

I had the wireless network available and used it always. Suddenly yesterday My computer does not connect to any wireless networks. I checked it and "View my available Wireless Networks" is completely empty. What do I do? coz when I got no available networks, how can I connect it? I did all rebooting computer, wireless router and so on. So please help me now as I'm on my brother's computer and its working fine with him even though he uses the same network. Its urgent guys, thanks in advance!
