When I first got my laptop the wireless worked fine but since then I've had some rather puzzling issues. Even though my wireless is turned on, I can't seem to detect wireless networks. However, my computer will still automatically connect to wireless networks that I have already accessed or that are set as default. So, when I'm at home, it'll detect that same wireless I've had for two years now but if I try to get on a friend's network, my computer doesn't find anything. This has been going on for six months now and I'm finally fed up. Of course, I've tried all the obvious things: restarting the computer, turning my wireless card on and off, making sure I have all of the latest windows updates, etc. but none of it has worked. I'm getting really fed up with this thing. Any advice would be greatly appreciated. Please help guys!
