Greetings folks - long time lurker (decade+) first time poster :)
I've been fighting problems since we moved in 5 years ago. Gone through 3 Cable Modems, replaced all CATV cable with Quad shield cable multiple times. Tried about 6 different makes of 1-2 balanced splitters. Had numerous techs out. They replaced the outside post (which helped a ton) and the drop line twice. Handheld signal analyzer checks out fine, but I have between some and massive packet loss and blocky/pausing TV as well. I've gotten so frustrated in the last several months that I've gotten a back up DSL line that I'm now just routing all UDP traffic through as the cable line is unusable for anything realtime (which is the whole reason we're paying for Gigabit!). This effectively rules out anything on my network and PC imho since games and RDP are just fine routing through the DSL line. The tech that came out the last two times agrees with my suspicion that the problem is at the headend. Any help getting this addressed would be greatly appreciated! I'm at my wit's end! The current cable modem is an Arris SB8200, router is EdgeRouter4 on v1.10.10 firmware. PC is Windows 10 1809, i7 7700k, Samsung 970 EVO NVMe, Asus RTX2080 Ti, 32GB ram, wired via CAT6, 24 port Unifi Gigabit managed PoE switch. All network cable is CAT6. Cable modem to splitter is about 4 feet of RG6 quad shield, splitter to outside box is about 70 feet of the same RG6 quad shield.
