Re: SIP DNS Query Failure - Periodic loss of Internet - Manual cycle of the modem required

Just came across this and have the same exact issues. I also have a T25 Modem (that I purchased) and is fully supported by Comcast.  Once a week I lose DNS to my network and have to manually power my modem.  I had a tech out last week who said it was my multi room splitter that he replaced with a 1-2 output splitter, 1 for line coming into the house and the 1 split goes to my DVR an the other my T25.  Had to restart after that an everything worked up until 1:00 am CST today 9/29/20 when the modem reached out for a DNS Query/Registration.

Attached is my Event Log.  I have a Sr. Tech scheduled to come ot tomorrow to see what they can do.  TBD.

We just got rid of the CM1150V - had to reboot that thing several times / day to even have any internet, then 3 tech visits to the house--they repaired outside issues including our next door neighbor's house which was causing significant signal ingress into our house.  After all that the CM1150V was still failing, which made us determine it HAD to be the modem.  After the initial provisioning it lasted almost 5 days before we lost internet the first time, now it requires a reboot about every 4 days. This morning it was a day and a half.  If this doesn't get resolved I really don't care about paying the termination fee, I just need working, consisent internet. 

 

Would someone from Xfinity please advise, it looks like several (likely many) of us are having this exact same issue!!!
