I suppose it is possible, I'm with Tiscali Broadband and have no such problem so the disconnecting is probably caused by another source such as incorrect settings or some sort of virus. I'd try deleting and reinstalling the modem first and see what happens. Is your friends anti virus up to date and what software is it ie Norton, AVG ? What operating system win Xp or 98. It could well be something else such as a corrupt setting or some program trying to access the internet when shes already online causing the connection to drop. Really need more info.
