OK so my sync problems are sorted now so that's not the issue here.
a router with a Broadcom chip is best for standard ADSL broadband that I have. My current DG834G hasn't got that,
No offence, but the title of this thread is about a new router! Nothing to do with problems from before! However, it was the cable I was using from the phone socket to the router. I bought a shielded one.
ADSL24 who advise a broadcom one is better.
