Channels bonds
Hello, I got this new modem and I have few problems, one is that hour time do not match, because of spring hour change (I do not think this is a problem), also I have few criticals and warning on event log about "Dynamic Range Window violation", "Started Unicast Maintenance Ranging - No Response received - T3 time-out;" Time Not Established
And the last one is that I have only 8 upstream bonded channels but only 4 of them are locked, I tried to talk to an Xfinity agent about this but it says it is modem problem.

Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, bad/old/cheap connectors, or corroded connections. Replace them if you do.
If you can, simply connect the modem right where the coax comes into the home. This prevents wiring in the home from being the issue. And some ISP’s charge if the wiring issue is in the home. So this helps prevent this.Once you've done that. try it, if it doesn't help, take a screensnip of the cable connections page and event logs and post back here.
I tried some of the things you said and now I got this, the only warning, rest of them are notices
REG-RSP-MP Mismatch Between Calculated Value for P1.6hi Compared to CCAP Provided Value
But I do not understand why 4 of them are not locked

But it helps if you have the screen snips of upload/download the the logs.
