Does it connect elsewhere (say, any free WiFi, school, work, friends, family)?
And can you post the output of ipconfig?
My laptop does not connect to the internet on the wireless networks in my flat. It will connect to the network, but will not have internet access. There are several unsecured wireless networks available run by the flat and I can't connect to the internet on any of them, whereas other members of the flats and my flatmates are able to. This suggests there is not a problem as such with the router, turning it off and on again has already been attempted. When I moved in, the man in charge of maintaining/organising etc the flats took my MAC address and allowed my laptop access. Yet I cannot connect to the internet. I went to my uni's library and connected to the internet no problem. I have tried turning off my internet security, looking at the properties of the wireless connection and attempting to edit settings (changing them back again afterwards), and nothing seems to be working. I have taken a printscreen of my network status here <a href="http://i53.tinypic.com/o6hgs7.jpg" target="_blank"><font color="#0044dc">http://i53.tinypic.com/o6hgs7.jpg</font></a> in case it sheds some light on the problem. Thanks in advance for your help!
