I'm fairly new to these boards and have seen people posting up their power levels from 192.168.100.1 and was wondering if anyone could tell me what these actually do to your connection and whether I should contact VM regarding mine. Any help would be appreciated

Downstream Lock : Locked
Downstream Channel Id : 1
Downstream Frequency : 586750000 Hz
Downstream Modulation : QAM64
Downstream Symbol Rate : 6952 Ksym/sec
Downstream Interleave Depth : taps12Increment17
Downstream Receive Power Level : -11.3 dBmV
Downstream SNR : 32.1 dB

Upstream Lock : Locked
Upstream Channel ID : 3
Upstream Frequency : 42800000 Hz
Upstream Modulation : QPSK
Upstream Symbol Rate : 2560 Ksym/sec
Upstream transmit Power Level : 38.0 dBmV
Upstream Mini-Slot Size : 2

The signal has to be in between thresholds to work correctly. Your downstream is well out of the threshold and you should phone VM for a technician to come out. However, if you're not having issues with your service, I wouldn't bother.

There's vast amounts of useful information over at Robin Walker's site:

The downstream power level is suspect - ideally this should be 0 although +5 to -5 is usually allowed. Do you find that the SYNC light (im assuming you have an NTL or Virgin branded modem here) goes out at all? If so, you need an engineer to come look at it.
