CODA56 modem randomly dropping internet connection

I have a new Hitron CODA56 modem on Xfinity cable internet. Last 4 months or so i've been randomly dropping connection. Seems to happen during high loads but I have Gigabit Extra.
I also have my own router: TP-Link Deco XE75.
I have seen this issue posted before so I will try to add as much info as possible to avoid redundancy.

All devices drop at the same time as the router goes red indicating no internet. Plugging PC into the modem directly reveals no internet, even though lights on modem seem fine (blue and green).

Restarting the modem does seem to fix the issue, however like the previous poster of the same issue, rebooting the modem EVERYTIME is not practical.

Adding to the chorus. Our CODA56 was fine when first purchased late last year, but now seems to drop connection every 1-3 weeks although status lights are fine.
