I agree and think it's an Xfinity issue. I thought I would post a message to see if others have had the same issue. I'm hoping someone might know how to resolve it or can confirm that its an issue with Xfinity.
Are the signal status numbers in spec ? The values are there in those tips.
Thanks for that info. After a quick review the issue seems to be "critical T3 timeouts" I'm seeing the modem reset everytime the T3 timeouts happen. I now need to figure out what's causing the issue.
The upstream power is too high and it may be intermittently fluctuating even higher 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 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 testIf 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.
The filter is a FRSA50, below are the stats without the filter.
Okay, I went out and removed the 3-way splitter and did a direct connection to the modem. I only use Xfinity for internet so this isn't an issue moving forward. See below for the new data.
It's better, but I would still like to see a bit more wiggle room. 40 to 45 dB would be ideal.
As far as that filter goes, it depends on what type it is and why it was put there. If it is a MoCA POE filter, and you don't have or use MoCA, then it can be removed. If it is a noise filter that was put there by Comcast you may or may not still need it. Try removing it and see what happens. It may be benign and not causing any loss, and could possibly be left alone or re-installed. YMMV.
I also noticed there was a filter before the main line was going into the 3-way. Should I keep that on or remove it now that it's a direct line into the modem?
Can't thank you enough! You're the best! Thanks for all the help today.
My pleasure !! I hope that things hold up for you ! Good luck !
