Internet Connection Issues - Intermittent Disconnections and Signal Quality Concerns

In an effort to try to obtain better connectivity, check to see if there are there any excess/unneeded coax cable splitters in the line leading to the modem that can be eliminated/re-configured. Any splitters that remain should be high quality and cable rated for 5-1000 MHz, bi-directional, and no gold-colored garbage from Radio Shack, Home Depot, Target, etc. Splitters should be swapped with known to be good / new ones to test.

Also check the coax cable for any damage such as cuts, nicks, abrasions, kinks, sharp bends, etc.

If there aren't any unneeded splitters that can be eliminated and if your coax wiring setup can't be reconfigured so that there is a single two-way splitter connected directly off of the drop from the street / pole with one port feeding the modem and the other port feeding the rest of the house/equipment with additional splits as needed and you've checked all the wiring and fittings for integrity and tightness and refresh them by taking them apart then check for and clean off any corrosion / oxidation on the center wire and put them back together again, then perhaps it's best to book a tech visit to investigate and correct.

Good luck with it !

Thank you for your response and suggestions. I appreciate your input on checking for splitters and the condition of the coax cable. However, I would like to emphasize that the issue only started today and is intermittent. Additionally, there are no splitters in my house, as the cable modem is connected to the wall with a short 1-meter cable.

Given the sudden onset of the issue and the intermittent nature of the disconnections, I believe there might be an external factor or a change in the network that is causing the problem. I am willing to perform any additional troubleshooting steps you may suggest, but if the issue persists, I would appreciate if a technician could be scheduled to investigate and resolve the problem.

Thank you for your assistance and understanding.

If there is nothing more that can be done to improve the connection quality, then yes, you'll need a tech visit as stated. I'm not an employee. I can't book that for you. You'll need to contact their customer service dept.

Bear in mind that if the premises facing techs can not find or fix a problem at your home, it is they who are responsible for escalating it to their line / network / maintenance dept. techs. The problem may lie beyond your home in the local neighborhood infrastructure somewhere but it is their S.O.P. to start at the home. And if the problem is found to be on their side of the demarcation point, there will not be any charge.

Good luck !

I too have started having issues today on my Arris SB8200. Nothing changed with my setup. Just seeing intermittent disconnects that last a few minutes.
