Issue started ~6 weeks ago but resolved itself until yesterday. I noticed half of my downstream channels are unlocked with 0db SNR, tons of correctables and uncorrectables when usually they're at 0. I have lots of print-to-PDFs from over the last 6 weeks.
Currently there are 2 more channels down than the last issue - currently have only 7 downstream channels locked and OFDM Locked @ 0db SNR.
Can you upload a picture of your signal levels? Also, what model modem do you have?

Basically same issue, though now more channels are dropping with 0db SNR
I'm still directly connected to the Cox Coax line, only one connection point at the freeway (grounded 1:1 terminal) no splitters in between modem and the ground.
