Internet connection drops/single low downstream power level
On October 10th we upgraded our internet to gigabit speeds and since then we have been having internet drops. The internet will sometimes drop multiple times per day every few hours or we go 2 whole days without any issues, then right back to dropping. When looking at the admin tools, I noticed there was a single downstream channel (25) that had an incredibly low power level at -60 and an SNR of 14, which sometimes goes to 7, and the modulation says UNSUPPORTED. When we upgraded, the tech that installed the new tv boxes and modem (TG4482A) replaced some cables and splitters as well, so I'd be surprised if that was it. We had a tech come a few days ago to swap the modem and check the cables and said everything looked fine on his end when he left, but the issues persisted. It is getting hard to put up with the issues as we have someone working from home and someone with online college courses as well. Any help with this would be nice. I've attached images of the downstream and upstream power levels below.
