When I look at the power levels posted above, it appears they are less than the minimum specification level of -7 dBmV and should be turned up and not down. A task for the ISP.
Thanks for the catch on that. Ya posted before not getting enough coffee today. The dash was't seen like it should have been. 🙄
Corrected.
Thank you Sir.
I ran a brand new Quad Shielded Cable from the outside connection straight to the Modem and now I am getting 45-46 DB Down and 39.5-41 DB Up so modem traffic looks good but still getting Critical "SYNC Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing" and Warning "MDD message timeout" in my event log and an unstable connection. Been on hold for 30 minutes waiting to talk to a human at Xfinity to ask them to ping the modem and tell them it 100% is on their end as it is a brand new Quad Shielded cable run from their termination to my brand new Modem.
And still have lots of Correctables and Un-correctables as well.
Keep on them.
