I used to be on Virgin dial-up. It worked fine on my old PC which had W95 on it. Earlier this year I bought a new PC with WXP on it. I used the same settings etc and had tremendous problems, particularly as regards actually getting through and then being disconnected after a few seconds. After several lengthy telephone conversations / emails with Virgin, they said that the problems were probably caused by WXP and suggested I go back to W95! That was the day Virgin became my ex-ISP. I now have NTL broadband. Apart from the occasional hiccup, it's fine.
