I have a very strange issue for my broadband. The connection is not working via wireless connection when use a window machine, but via cable the connection is working.
Also all apple device is working via wireless connection. I have reset the modem for a few times, the first a few try resolved the issue, but recently even the reset makes no effect. Not sure if anyone can give a light?
if the cable is fine and other wifi devices are fine, then its an issue with the PC wifi, not the modem or internet.
You'll need to describe more what you see on the PC wifi when you try to connect , eg can you see wifi name, does the wifi connect or not, have you cleared the saved wifi password off the PC and reconnected, what errors or messages do you get, can you show screen shots?
