I've had the same problem trying to set up the 7700N with the static-IP O2 broadband service. There simply isn't any way of entering all the necessary details into the router config to get an internet connection.
The web page linked by billion_fan appears to provide no information at all - it just tells you to log in to the router, nothing else.
Has anyone been able to get the 7700N up and running with O2 or Be, please? Or can anyone from Billion provide some advice? Many thanks.
That's most helpful. I'm now up and running, thanks very much indeed.
There's just one slight headache: it seems that I can maintain an internet connection only if I keep the DNS Proxy enabled in the router config. This appears to be because if I disable it, as I would prefer to do, the addresses of my chosen DNS nameservers aren't transmitted to my computer's operating system (Linux) on restarting. Any thoughts about this, please? Thanks again.
