"Dynamic Range Window violation"

Router - Google Nest Wifi

Cable Modem - Arris SB8200

 

Brought my house 7 years ago, and enjoyed perfect internet up until 10ish days ago.  Since then I have been getting constant timeouts and random complete disconnections from comcast Service. 

 

On multiple machines wired and wireless continous pings to google.com, comcast gateway, work-vpn and my google wifi gateway; once a timeout happens it would occur on everything at the exact sametime except the ping to my wifi gateway; I believe  this tells me everything is good upto the cablemodem, far as interference goes.

 

Overnight my conitunious pings (with time stamps) come back perfect up until about 8:30am and then constant drops until 11pm, even on weekends.  I had 3 different comcast technicions come to my house to check everything but nothing was ever resolved.  According to the Techs everything was great, whilst I am still getting timeouts every 10-15 seconds across the board on multiple computers. 

 

My Google Wifi is brand new, and I also purchased an Arris SB33 to validate if my cable modem wasnt the problem.  Problem persits on any hardware configuration, even when plugging a laptop directly into the cable modem.. Confirmed it has nothing to do wiht my internal network.

 

The Xfinity Network Engineer has been checking my node for interference and he says everything is good, and he doesnt see any noise.. and there isnt anything else for him to do.  There is no esculation path..

 

Googling my issue I stumbled onto people with the same Cablem Modems experiencing the same problem, and see the same events displaying in my cablemodems event log.  They never show their resolution to the issue other than Comcast or Cox stepping in to resolve.

 

I have read a hard reset helps with the Dynamic Range Window Vilation, but even after hardreset it comes back.. After a hard reset on my cablemodem and these events came back..  Someone who is more familar with this, are my numbers looking ok? or is there anything else I can do to help my connection?

 

Please help, this is impacting my kids connections into school, my connection into work, and my gaming connections aftewards..  as mentioned my connection was perfect up unto 2 weeks ago, now an utter nightmare up unto 11pm at night.

 

Thanks

Re: "Dynamic Range Window violation"

The downstream power is on the high side 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.

Is there an amplifier or a powered splitter on the coax line leading to the modem ? If so, try bypassing it and see.

Re: "Dynamic Range Window violation"

There is no amps, but 1 splitter splitting to the cable TV.. I bypassed the splitter and  the cable from outside is directly plugged into the cable modem.  It looks like the downstream power increased...   How can we adjust or dampen this power output?
