Recent Internet Drops with New Modem MB8600 (worked great for 2 weeks after initial install)

Recently returned my xfi gateway and purchased a Motorola MB8600. Worked great for a couple of weeks and recently had quite a few drops. Seemed like it was once a day for 1-2 weeks, reset modem and router and be back up for a day. I spent about an hour on the chat with an xfitiny tech who was resetting and "addressing my situation", since then its dropped about every 36-48 hours Yay improvement?). The chat person said that it was a hardware issue and that the modem was potentially at fault. Unfortunately while resetting/rebooting I lost my connection to said tech and didnt hear back from him (plus i ran out of time).

WiFi signal (Eeero pro 6) is super solid throughout the house

Coax comes into the house, directly into the xfinity splitter and then into the modem. Nothing extraneous.

Looking for suggestions.
