Internet goes out in the afternoon each day
Hi everyone,
I have an Arris 8200 Docsis 3.1 modern connected to a Synology router.
We seem to have an issue almost every year.
Usually during the afternoon (between 12 - 2 pm EST) my internet connection will go out for about 2-5 mins multiple times.
In the past we've had Comcast come out and usually it takes two - four visits for a problem to be found (the test usually show every thing is in spec when tested on the street, house, and at the modem)
On different occasions the issue was fixed by replacing the cable that runs from the street to my house ( I believe that's been done twice) and last time, I think, it was some connections at point of the house)
Anyway, here is my modem specs and recent log - is there anything I can say when Comcast arrives to make this easier.
Like I've said, in the past, it usually takes multiple visits - Also, why does this seem to happen every year and in the afternoon mostly?

The downstream power is low / weak and it may be intermittently fluctuating even lower / out of spec. That can cause random disconnects, spontaneous re-booting of the modem, speed, packet loss, latency problems, and the un-bonding of channels.
In an effort to try to obtain better connectivity / more wiggle room, check to see if there are 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 5-1002 MHz, bi-directional, and no gold colored garbage from Home Depot, Target, Wal-Mart, 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 !
