Hi, all – Please forgive my ignorance as I’m learning and trying to do what I can on my end to fix a problem before trying to explain it to a tech who will say “there’s nothing we can do.”

I have residential service at 1Gb with Optimum (formerly Suddenlink). The part of the connection we’re on circles one block as this was recently installed. They brought fiber to the end of the street and connected it to the node and I’m on one of the 12 or so taps. They buried RG11 from the pedestal to the side of my house. Roughly 80-90 feet. The cable is connected inside the box on the side of the house to the grounding block. Then it was connected using RG6 going inside my house. Ever since they installed in June, the signal has dropped out quite a bit. The latency has been the biggest issue with spikes into the 500’s. I was on their Altice proprietary wireless modem. I then switched over to a business account and they changed my modem to the Arris CM3200A. Continued to have the same issues. At the time, I wasn’t doing much that warranted an immediate correction regarding the latency spikes/drops.

About a week ago I decided to do some tracing and followed the RG6 under the house and into a giant spool and then up to the tech closet. I measured the cable to be about 40-50 feet. There was also a clean cut in the cable exposing the copper conductor. Thinking that is the first step to solving this issue, I removed the RG6 and installed new RG11, 25 feet, from the grounding block inside the box on the house and directly to the back of the modem. No splitters anywhere in the chain. The other change I made was buying my own modem. I bought the Arris SB8200 to see if that would make a difference. Now, the drops and the latency spikes were doing better…but not eliminated. As I’m now at a point where I’m relying on a solid internet connection for work, I cannot afford to have the signal drop as often as it has been now. I called Arris and spoke with them about what the SNR and dBmV should be. They said my upstream pwr was too low and out of spec. So, I happen to have a brand-new Motorola MB8600. I figured I’d give that a try and see what would happen. Now…from what I can see…some of these signals may be a bit low but my biggest concern is all these uncorrected on the downstream bonded channels. What does this mean, exactly? I’m still getting occasional drops but not nearly as many as before the modem and cable change. I’m not sure what else I can do, and I know when the tech arrives, he’s going to look at the tap and say “everything I’m seeing on my end is good” and since I’m not using their modem, there is nothing they can do.

Thoughts? Suggestions? Images to the latest connection specs BELOW

For shits and giggles, I’ve got the modem going into a UDM Pro.

TIA.
