CM1200 New high MS

do you also have your cable connections page info?
If there was splitters in the attic, i'd try to connect right where the coax enters the home. I've seen older coax in homes cause issues
So here's a better explanation. telephone Line to house > Outside splitter that splits to attic/living room > Travels through the wall to the Inside splitter in my living room > My modem/router. The outside splitter had a cable going into the attic in which i disconnected everything in the attic, but I didn't remove that cable. Should I pursue removing that cable from the outside splitter?. Are you asking to disconnect the living room splitter and connect that cable directly to my modem? Thanks in advance. Cable connections page:

you've got low upstream and a bit of variation in the downstream.
I'd remove the outside splitter and just off the cable going to the living room. If its needed for cabler tv, just for the time being, don't use it. Just go cable----->modem. with no splitters. See how it works and after using it for a bit, then rerun the logs and cable connections page. See how stable it stays.
Checked outside and it goes line to the initial cable into the living room at this point then to the splitter.. Going to connect directly to the modem and get rid of the splitter and see what happens. I'm actually calling my ISP again at this time to see what's going on. I checked the cable that goes from outside to inside and its RG 6. Wiring to the attic has been disconnected from the outside as well. I'm confused to what's going on at this point.
