internet keeps disonnecting...modem stats posted...no ranging response received T3 timeout

Hello Xfinity Fourm, signals1.PNG

 

Getting disconnected every afternoon.  Reset sometimes fixes issues, but multple resets. Sometimes it will take hours till it stable.  See attached photo for stats.

 

 

Thanks in advance.

Can't see your pic. Since you are a new poster, it likely needs to be approved by a Forum Admin.

You could try hosting it at one of those free third-party pic hosting sites like Photobucket or Imgur and post the link to it here.

The upstream power is too high / out of spec. That can cause random disconnects, spontaneous re-booting of the modem, and speed 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.

Thanks a lot.  We dont have any splitters, but we did have a cable cut outside years ago.  Instead of running a new cable, they patched it up by cabling up the cut cables together.  I might have a tech come out to take a look at it and the signal levels.  

 

 

Thanks again!
