Not 100% sure as I'm not ex-ntl trained but

Downstream Receive Power Level : -10.0 dBmV
Downstream SNR : 29.5 dB

Power level looks too low and SNR looks low too.
Can you post the upstream as you posted downstream levels twice.

Low SNR will cause packet loss and intermittent connection.
If the levels above are below the ex-ntl limits you'll need to call tech support for an engineer visit or book it through the newsgroups.
Either way I'd suggest doing the tests again with the router removed. It rules out the router and stops a clueless agent agent blaming the router and will get a resolution quicker.
Hopefully an ex-ntl tech will be able to confirm the levels.
