About a month ago we had cable TV installed and ever since the SNR on the modem has been significantly lower than normal, causing random cut offs, mainly around 11pm - 6am period, never other times.

Downstream Receive Power Level : 5.53 dBmv
Downstream SNR : 28.11 dB
Upstream Transmit Power Level : 47.50 dBmv

Those are my levels at the moment. The SNR varies between 26dB and 32dB. Before the TV was installed, we had an SNR of 36dB+

If my broadband hasn't dropped out, you can see live SNR stats on http://m3ezw.no-ip.com:85/routerstats.htm

I have checked the cables and done my own trouble-shooting, and I have done the following:

1. Removed the TV cable
2. Removed the splitter
3. Tried with and without the attenuator on the modem
4. Replaced the connector on the end of the cable for the modem
5. Reseated all connectors in their plugs

None of those seemed to have any effect on the SNR level.

Does anyone have any clue as to what else could be causing this problem? It only started when we had the TV installed, yet the TV doesn't seem to have any effect on it (since it was tested with it removed).

If I need a technician out I take it that the call out would be free? I assumed I could correct this on my own but it seems not in this case.

Seems this is goodbye to 6 years flawless service from VM!

All help appreciated.

Thanks.
