T3 time-out- Please help

Hi,

I am having random internet disconnect issues over a couple of months now. Xfinity Customer Service both human and robot directing to reboot the modem, didn't solve the problem. 

So,  finally 1 tech visited this week--checked the signal levels, replaced the coxial connectors and it worked fine during their visit. But the problem resurfaced next day. I have only 1 line from the main service to my modem, no splitters. it's difficult to work from home with disconnecting internet. Can someone please help me resolve this issue? Here are my modem power levels and logs.

Thank you very much in advance

Re: T3 time-out- Please help

In your last post the upstream power was too high 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.

Re: T3 time-out- Please help

So a tech came today, inspected the lines, said connection (line to my house)at the street was bad. Fixed the connection, checked the signal levels- said good. Hopefully it solves the problem. Thanks. Here are the signal levels:
