Re: no dns connectivity

Forget about the DNS server connectivity it is an incorrect result from the router
Your problem is that your line is apparently banded http://www.plus.net/support/broadband/speed_guide/broadband_terminology.shtml#bandedProfiles with an enormous number of errors
The first thing is do you have a master socket with a removable lower faceplate
Second are you absolutely sure that everything attached to the phone system including Sky Box, Monitored Alarm, etc is filtered

Re: no dns connectivity

FYI I've performed some diagnostics and the line isn't banded.

Re: no dns connectivity

Just to add to Adam's post, he's still running some checks. It's a 20CN line so it's not banded.

Re: no dns connectivity

I've submitted an SNR reset which should hopefully resolve this.
However @ox06 we're seeing a few disconnections which might be causing some issues. Is this something you're aware of?
