Internet dropping multiple times a day

I've been having some issues with my internet dropping numerous times a day, the only solution being to reset my router which seems to re-sync the router with the modem and all is well again.  I had a tech out recently and he replaced a few splitters, ran a new cable to the main drop for the building and said it all looked okay, however I'm still having some issues, and looking for any advice.

Equipment is a Motorola SB6141 modem and a TPLink Archer C1200 router, both were purchased brand new in May of last year and have been fine with no issues since.

Here's the signal info from my Modem's Signal page :

Am I missing something here? I've factory reset the router and set it back up from scratch as well as ensured the firmware is up to date, but no changes.  Any advice?
