Re: [Connectivity] Lost downstream and upstream bonding i would assume he meant high Tx level....transmit but 50 upstream isnt that high...fairly normal...
bonding is controlled viz the cmts....nothing in the field, or that a tech could do would disable/enable it.
i would call in and ask what your upstream signal to noise (usnr) is....i would suspect it to be low (under 30) and that is whats causing your modem to drop its connection...

| I am not in a position to interpret your line stats but I do have a SB6120 in Sacramento with Comcast. I experience a spontaneous going from blue to green indicating the loss of bonding. I power cycle the modem and I go back to blue. I only have HSI so there are no splitters at my end. Perhaps the problem is more global with Comcast or a failure of the SB6120. Since every speedtest I run shows no difference green or blue and none of the multiple devices which are always connected including VOiP, from a different provider, have any issues I figured I would leave well enough alone. Will say the 6120 is faster than my old 2.0 modem green or blue. |

No matter what else is going on in your area, it is very likely that the 51 dB on the upstream is pointing at current or future trouble,
Call for a tech, and let them work on it in person.
(as gar187er  said it may actually be the noise level, but rather than guess, call the local expert) |
