6 Bounded Upload Channels - Multiple Issues for months - Countless Tech visits - Need Line Tech Support not Level 1
I've had issues since October 2021 and have replaced my MB8600 with an S33, I've had countless techs out, replaced every coax (in house, and to pedestal), spitter, connector and nobody can resolve my power levels/disconnects.
Every other month they keep changing the number of bounded upload channels I have, which to mean indicates there is a bigger problem going on?
I have never seen 6 before. (what does this indicate)
And Not sure why the OFDM channel is labeled channel 193 and is at a much lower power level than all the rest of the channels, i was under impression that the channels should all be +/- 3db of each other?
A tech that came out 4 days ago told me it's not my house and something about having to put a work order in with the network team to correct a "slope" issue? I googled this and I couldn't find any reference to the term slope being used with cable modems, but he said the signal reaching my house was at the wrong slope?
He claimed that once the network team did there thing and adjusted my levels and to my TX power readings into the 40-45 range which is what aris's website says are needed.... that the correctable and uncorrectable errors and the T3/T4s would go away.
However they haven't... is there any experts out there than can help? Support just keeps sending techs who just replace fittings.
I've proven its not the modem or the wires by replacing modem and putting modem on a 3 feet coax directly to box and tech confirmed with his own equipment.
The ironic thing is I am 300 yards away from the main node for this entire area, but the wired the subdivision I am instead the 2 to last house where the line travels 2 blocks via fiber then provides server for 50+ homes, hits an Amp then another 5 then I get service..
Please help me get this escalated to the correct team and past level 1 support, it is exhausting to answer if checked for loose connections, reboot modem, and for them just to schedule another tech visit when the problem is beyond the Pedestal Box in the backyard.
PS. This is a screenshot after the modem being rebooted 14hrs ago, so the errors come in extremely fast.

Sorry to hear you have been having problems for so long.
Per my thread you commented on, this sounds similar to my problem.
What seem to have helped me was repeating to each Comcast support rep.
“Arris states the problem is the Upstream QAM needs to be between 45 and 51
dBmV power level. Can you send someone who can adjust that issue?”
your values are all still below 45.
I will say that Comcast attempted multiple changes to their side of the net work before coming out and kept calling to ask if the service was working properly.
Each time I would check the upstream QAM values, which improved, but did not all land in the required range, so I told them the service was not working properly (it went from failing on 80% of my calls to only 15%, but was still unstable.
Best of luck!
