Xumo resets constantly

Moved into an apartment and xfinity is the only game in town. I have their router and got their Xumo for streaming. Maybe a month in, this thing keeps restarting my tv. At first it will be with quite some time between restarts, but keeps speeding up until my tv is just blinking on and off. It's even crashing youtube then playing a new video from the same channel upon reopening. I saw a post from 3 years ago with the same issue. Cool that this is a persistent and unresolved issue for a company of this size. Any solutions, community?
