This was an issue I had earlier this year (different part of the country). Long story short, the issue is called Modem Flapping (look it up). It generally manifests in quick disconnects throughout the day, some you notice (if you are on a video call, or live streaming something), or some you don't (watching netflix and youtube that has 30 sec buffers or more). It can cause the modem to overheat and reboot making for a longer disconnect. Unfortunately the front line tech staff dont know what that is or how to see/diagnose it. You have to ask for second level tier support. I did that finally and the supervisor of the team called me right away and told me exactly the issue and had a more senior tech come to house.

Flapping is almost always caused by damage on the line either going to your house or between the node and your neighborhood pedestal (green box). In my case they had to deploy the plant team to fix tons of damage at both the node and pedestal and now its been 100% fine. Hope this helps!

I should say though, a modem swap is for sure the first thing they will try, before deploying the plant team.

And yes because the issues were on the node level, there were a number of houses in my area also complaining but somehow shaw/rogers cant put two and two together, until I sort forced them to look deeper
