I notice today my Downstream Power Level has changed from +8dB to now -2dB and SNR is 38dB, that is a big difference, so I might have a problem since we had falling trees during the last snow storm up here in Cascade MD, should I put in a troubleshooting ticket.

the point is, when the repair Tech came out to do the setup he used all my equipment and not his because mine was better then what comcast offered and he was very happy with the results, less cable loss, better splitters, soild connectors not cables, splitting the Modem/on-demand off from the other TV ports, and he liked the download pwr level which was +8dB/SNA 38dB which was the best he seen in a while.

The signal stats should never fluctuate more than 2-3 dB Even though your downstream power has actually gotten better. What does the upstream power level figure look like ? Keep an eye on your stats for a while and see if they remain relatvely stable. If not. and you experience issues even with your T.V. reception, you should call it back in for a tech to investigate further.

-10 dBmV to +10 dBmV is the spec for downstream power levels.
It's actually even tighter now-a-days in upgraded to DOCSIS 3 systems. -7 dB to +7 dB is the preferred range with - 10 dB to +10 dB being the very outer limits.

Upstream is +49dB.
and most likely why the Tech liked my setup because the on-demand box.
The Wife states the On-demand picture is not always good , it has rips during playback.
