Daily Service Interruptions
Every afternoon, my internet goes down. This has been happening for a week or so now. The exact same thing happened last year for about six months and then it stopped. Yesterday it went out at 2:226pm central time and came back a couple of minutes before 3pm. Let me clarify that, it came back for a couple of minutes during that time and went right back down, but it came back for the rest of the day at right before 3pm. It always happens the exact same way and always happens in the afternoon, last year and now. This has to be on Xfinity's end, right?

The upstream power is too high / out of spec. That can cause random disconnects, spontaneous re-booting of the modem, speed, packet loss, and latency problems.
In a self troubleshooting effort to try to obtain better connectivity / more wiggle room, 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 5-1002 MHz, bi-directional, and no gold colored garbage types like GE, RadioShack, RCA, Philips, Leviton, Magnavox, and Rocketfish from big box stores like Home Depot, Lowes, Target, Wal-Mart etc. Splitters should be swapped with known to be good / new ones to test
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.

There are no splitters. It's coming straight in and to my modem. Thanks. I had a tech come out last year when it was doing this and he said everything was fine. I guess I will wait for six months or until Google Fiber is available in my area. lol

The numbers don't lie. You should get the techs involved again. Show them this thread.
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.
Good luck !
