Re: [Connectivity] Modem keeps losing upstream channel bonding

said by Morac:

Now I'm getting packet loss (about 5 to 10% depending on test). It does look like an upstream problem.

Edit:

Called into Comcast and was told my signals are "bad". Upstream SNR is 27.1 and receiving power level at the headend is -0.9 (I was told this was the biggest issue).

That SNR of 27dB is WAYY low. You want to see about 35-37dB. The scale is logarithmic so 37dB is like 10x as much as 27dB.

You may be confusing that with the downstream SNR and not the upstream ?

Seeing as high as 35-37 dB on the uSNR as read at the CMTS would be quite rare, if not impossible.
