Xfi modem drops smart home devices randomly

Recently upgraded my home internet from 200mbps to the fastest 1200mbps plan.This came with a new xfi modem. After initial setup everything worked fine. Added all my smart home devices and they worked as they should. Day two I noticed that none of my home smart devices were connected to the network (ring cameras, smart lights, echo dots, smart litter boxes, etc). After a modem reset, they started working as usual. The issue is, multiple times a day, the modem will disconnect these devices and I'm forced to restart the modem again to get them back online. I've tried forgetting the network on each device (takes hours) and start over and it's the same thing. Never had this issue with my last xfinity modem, so what's the deal?
