Periodic connection drops - Hourly, now about every 15 minutes or less

FYI - Chatted with tech yesterday, got a new modem from the xFinity store today and still having same issue. TV service has been fine entire time. Even disconnected TV's and connected from outside box straight to modem. This is just weird - seems like upstream equipment doesn't like this type of modem or something. Called in today and sending tech out tomorrow.

The upstream power is on the high side (especially on channel 2) and it may be intermittently fluctuating even higher to out of spec levels. 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. Good luck !

Replaced literally all the inside wiring. Ran two new  RG6 runs from the outside box, and placed the 2 port splitter that came with the self-install kit inside the box. Ran one directly to the cable modem in the basement, and one to another new 2 port splitter feeding the 2 cable boxes. Ran a new cable to one box, and use a second existing connection to the other. Also plugged the xfi box into a different outlet behind a UPS. Even with that and the new modem, still the same result. Also noticed the TV gets a bit digital periodically.

Hopefully the tech tomorrow figures something out.

Numbers are a little differnt now though

Also forgot to note I get these in the log each time it bounces

O/k the stats are better ! Those router component event entries are not helpful.. Good luck with the tech visit ! Please post back with the outcome.

Is there some way to escalate? After a technician visit, and three new modems, I need to get this figured out if they are going to refuse to let me switch back to my own modem that worked perfectly fine with the same internet plan. I'll happily pay the full $50/month for unlimited data at this point to have working internet again.

Technician couldn't find any issues with the connection or wiring, but he went ahead and re-terminated everything, and replaced the splitters (noting the old wiring was fine, and now not particularly happy having spent $150 on coax, etc knowing that it made no difference). The issue persisted, so he swapped out the modem (3rd modem so far this week). He was really confused as there was no reason it should be dropping sync and reccomended I witch back to the SB6190 if the issue persisted. I was optimistic as it stayed up for a few hours and  I did notice that this modem listed the manufacturer as Technicolor vs Arris, despite the same design.

The issues then started up again and it's dropping constantly.

I called into suport to request to switch back to my old modem (a fairly new Surfboard 6190) that I never had any issues with and was getting the full plan speed before (over 300Mbps) and had no connection issues until I switched to the xFi modem. She said I could not because it only supports 60Mbps. Really? It's a DOCSIS 3.0 modem that can support 1GBPS, and I was already getting 300Mbps before.

I can't deal with this anymore. I just want to go back to where I was a week ago, with internet that actually worked, with my own modem which very much can support the speed I have.

Good to hear !! Now closing this thread. Post again if there are further problems.
