my mate has just installed his router to get bt broadband (against my advice I may add), but the free router may have played a part in it.
well he tried for ages to get his connection, but no joy.
He was told he had to un-install his Norton anti virus as that was probably the cause of the problems. Hope Norton don't find out about this, the biggest anti virus company having a problem that bt state is a problem with their software.
Then having uninstalled it and installed AVG still no luck.
Despite a monumental amount of phone calls (approx 1 hour for a each telephone call to be answered) he was old it was the dns settings.
This was after a ping test had been done and the the internet was accessed by using IP addresses rather than the dns server.
This was only disclosed after BT were told that the account was going to be cancelled.
For gods sake BT stop being a arse and help your clients, this is not the first time I have known major problems with BT.
