Day 4 of slow and dropping internet
This is day 4 of horrific internet service. This began Thursday with things slowing to barely usable and then dropping connectivity altogether. Yesterday, I had had better speeds than I have ever seen from 10am until about 4am when service became horrific once again.
I have a tech visit scheduled for Jan 12 that was scheduled on Jan 6. I have worked online with numerous customer service agents and alleged techs, restarted the gateway so many times I have lost track of how many times that has been done.
Tonight, when service slows down into the single MB/s range, restarting gateway causes speed to resume for about 15 minutes, but then it slows back down again.
I see entries like this in the Firewall log:
| FW.IPv6 INPUT drop , 1586 Attempts, 2022/1/9 21:17:49 | Firewall Blocked |
| FW.IPv6 FORWARD drop , 14 Attempts, 2022/1/9 20:47:15 | Firewall Blocked |

The downstream power is way too high and the SNR's are too low / out of spec. That can cause random disconnects, spontaneous re-booting of the modem, speed, packet loss, latency problems, and the un-bonding of channels.
Is there a drop amplifier on the coax cable line leading to the modem ? If so, try removing / bypassing it and see. If not, you can try using a -6dB attenuator like this to knock down that power and see;

Please post back with any outcome.
