Jul 25, 2023 · Signal now about -4 to -5. I think as the sun heated my attic the splitter caused issues. Always happen about 9 to 10 am. The cable wiring I installed 35 years ago and there are a few junctions in the path. No dropout all day today. Problem solved. Being able to see change in signal level was a great help. My Arris CM820 page is https://192.168 ...

Feb 3, 2022 · @user_95f681I've checked on https://comca.st/3gpGdaZ and the CM8200a is not coming up in the search. After going through a filtered list that covers different speeds with DOCSIS 3.1 the only device that comes up is the Arris SB8200 up to 900 Mbps. Let me know if more info is needed.

Nov 3, 2023 · Here is a brief description of each page in the CM820 menu: Status - Provides information about the startup process of the Cable Modem.

I have xfinity cable service with my own compatible modem (Arris SB8200). I will the replacing the router currently connected to with a newer one (new one is a mesh based router). My questions: 1. Do I need to do anything other than - (1) turn off the current router - (2) turn off the modem - (3)

Apr 16, 2020 · ARRIS agent told Xfinity that the SB8200 requires a minimum upstream signal level of 45-51 dbmv. I am only getting 32.0/33 dBmV. Hence the reason the light is not blue. ARRIS agent recommended that Xfinity remove the modem from my account and setup a new profile from scratch to fix this.

Oct 19, 2024 · I recently replaced my Arris Surfboard SB8200 modem that I have been using for several years. It was apparently defective as I was only getting a download speed of around 40 Mbps from it for the past several weeks when I pay for 500 Mbps speed. An Xfinity technician came out and checked the speed of the cable going into the modem, which was fine.

Mar 23, 2024 · From Arris' Support: The Cable Operators (MSOs) have complete control of what cable modem/gateway hardware they will allow installed and the firmware it uses, this is because they own the coaxial cable that is connected to the ARRIS (G36), because of that the Firmware updates are pushed by them, and any update needed as well.

Mar 4, 2025 · Just upgraded to an Arris S34, but still only getting 40 Mbps upload speed I recently upgraded to the 2gbps/400mbps plan that became available in my area but was still getting slow upload speeds, so I just upgraded to the Arris S34 cable modem after seeing it on a list showing that it supports the next gen upload speeds.

Jan 10, 2025 · What is even more weird is that if I connect to the MAIN Deco(connected directly to the ARRIS S34 with cat8 ethernet) with my laptop via ethernet I can get about 1600-1800(even though the app still says its receiving higher than that), BUT if I skip the router completely and go connect directly to the ARRIS S34 modem with the laptop and the ...

Oct 28, 2024 · Arris XG1v4 I've recently received an Arris XG1v4 box as a replacement for an older, malfunctioning box, but the new box is horrible to work with. It seems like the sensor field is so narrow that if you don't hold your remote within the right area, which is the width of a silver dollar, there is no reaction from the box at all.
