Random 5 minutes outages each day. Worse in last few weeks. New Modem and levels within spec.
At my residence near Richmond Virginia for the last year around noon I would get an outage for about 5 minutes.
I attributed this to an IP swap as it was consistent. I went ahead and upgraded to a Netgear CM500 modem from my 3 year old CM400 in prep for faster speeds in the future. This made no difference to the issue. In the last few weeks these outages have started occuring more randomly sometimes in the morning, around noon, multiple times in the afternoon. Usually no more than 3 in one day but atleast 1 a day. Modem resets during the outages do nothing and the xfinity site cannot see the modem when an outage occurs.
I suspect a greater issue I have asked some neighbors who seem may have a similar problem. My modem reports good levels but logs the outages as t3 and t4 timeouts. Any help is appreciated, the line to the house is new as of Fall of 2016.
I only started noticing the issues February 2019 when I started working from home 1 day a week.
Below is the signal levels over 1 day. An outage occured around 8:30am 4/6/2020 and again around 2:30PM 4/6/2020
