Need to Restart Modem Multiple Times a Day

I need some guidance on how to get technical help with my very regular internet dropouts. I have an xfinity supplied gateway that is currently in bridge mode. Almost 2/3 times a day, I have to restart the device because I begin experiencing constant internet dropouts every minute or so until the modem has been restarted. I've already attempted getting a new Modem and am still experiencing the same issue. I've tried troubleshooting as a problem with my router, but restarting the router doesn't fix the issue and down right changing routers didn't change anything. I've tried going through the process with the chat bot through the xfinity app(which all xfinity resources seem to direct me to). the chat bot will ask if I've recently restarted the modem(I'm assuming it sees the device was power cycled) then asks if it resolved the issue. If I click "yes", the chat bot says "great" and ends the conversation. If I click "No" it will check for a signal and see everything as strong (Because it was just restarted). This issue has been going on for several months now and only seems to be getting worse. Not to mention our bill was just raised as if the service being provided warrants that.... Anyways, I'd really like some guidance on how to move forward. Otherwise I'll likely be switching ISP providers when this contract is up as they've just stared installing fiber in my area.
