So my brother just bought an old IBM ThinkPad running Windows XP. He wanted me to try and set it up for him, so he dropped it off at my place. Everything was going fine until I tried to connect to the internet. The wireless radio is ON, however it can't find any wireless networks in the area. I plugged it in via ethernet cable and got access right away. Once I unplugged it, nothing. On my laptop I can see at least 3 wireless networks in the area. However on the thinkpad, nothing. Any suggestions?
