Hi, I have a spare desktop computer on the veranda that was picking up my wireless with no problems, then my D-Link wireless modem started playing up and rang D-Link and she fixed everything up, but the computer on the veranda would not pick up the network, I could see it on the available wireless networks, and I fiddled around trying to connect, but now I can't see any available networks but the usb connector says it is working with good signal strength but there is no internet. I don't know what I have done.
