Random Modem Resets, several times over the last few days.

I plan to call Xfinity customer support this afternoon. These resets started randomly yesterday and have continued to happen. If I had to guess I would say it's happened 15 times between yesterday and this morning. I own my own modem Arris SB6190. I pulled the event logs from this morning and every reset has the same messages each time.

RCS Partial Service

Lost MDD Timeout

No Ranging Response received

TLV-11 unrecognized OID

My service has always been very solid so not sure what's going on. Any ideas? 

It's a major issue with distance learning and a spouse working from home. The constant resets makes video conferencing difficult.
