As has been said previously your downstream SNR is a little low and rcv power level is a little out (depending on what type of modem you have). I would suggest that you check the levels when service is slow and when service is fine. If the levels do not change then it's possibly a red herring and more an issue with erroring or upsream SNR on the HFC (these can only be monitored from the uBR by VM)

I can see however that you are in a QAM64 area so this is possibly just an issue with utilisation and nothing to do with your levels specifically.

Below are my downstream stats for comparison, I am using a NTL 250 :

Downstream Modulation : QAM256
Downstream Symbol Rate : 5360.537 Ksym/sec
Downstream Interleave Depth : taps32Increment4
Downstream Receive Power Level : 1.1 dBmV
Downstream SNR : 40.5 dB

Cable Modem Upstream
Upstream Lock : Locked
Upstream Channel ID : 2
Upstream Frequency : 18384000 Hz
Upstream Modulation : QPSK
Upstream Symbol Rate : 2560 Ksym/sec
