Currently around 40. What is good, bad ?

[Client62]

A good Downstream SNR is 33 dB or higher, hence 40 is fine.

The Downstream Power Level preferred range is -7 to 7 dBmV

The Upstream Modulation should be 64 qam

Personally, I would advise -6 to +10 for Downstream

T correct VM levels:

Downstream: no lower than -6dBmV and no higher than 10dBmV - Close to 0 is optimal. SNR >33 The actual DOCSIS spec allows a range of -13 dBmV to +17 dBmV

Upstream: no lower than 31dBmV and no higher than 50dBmV - 44dBmV -46dBmV is optimal. FTTP 27dBmV to 45bBmV

[DigitalDreams]

Downstream dBmV from 3.2 to 7

Upstream dBmV from 40 to 30.8, modulation 64QAM

Just fishing for possible reasons the engineers can't get a Hub5 happy on my connection (tried 4 now). Job passed to the network team.

Happy in what sense ?

Connected to the cable network or working splendidly in Router mode.

The former perhaps possible ... the latter pigs might fly.

What about the codeword counters? You can have a good SNR (average) and have ingress at the same time.
