Thanks Kymmy,

I have rebooted modem each time I tried the attempts described above.
I will try disabling wireless this evening when I get home from work.

Masque - yes I am a Virgin Media (ex-Blueyonder ex-Telewest) customer. As I said, the modem works perfectly well with 2 other PCs, so I cannot see how anything can be wrong there.
