Just googled seems a lot of people have had the same problem connecting this kit to Virgin Media cable Modems,the answer seems to be suspiciously simple,switch off the cable modem for ten minutes,then power everything up again, will try that tomorrow,had enough tonight.
This kit came with setup software,wondering if it is necessary at all? because there is a wireless setup icon already in Widows control panel.
I remember fannying about with the Virgin media cable modem setup disk when I first got Broadband, completely unnecessary as it turned out.
