Xfinity Gigabit & Motorola MB8600 Constant dropping / T3 timeouts

Having read numerous accounts similar to mine, I'm hoping the solution has been identified (or can be).  I have Gigabit service and my 4 month old MB8600 was great initially and has been getting worse and worse, now with T3 timeouts hourly.  Sometimes it recovers itself after a few minutes but usually I have to power cycle the modem (which works every time - for a little while).  

 

I have logs I can share and rest of set-up is basically a Google Wifi plugged into ethernet port of modem, which I then connect to a switch which connects to my downstream devices such as Apple TV etc.  I've read about cable tilt, docsis 3.1 issues, etc.  I don't own the building (townhouse) but am connecting directly from wall to modem - no splitters I'm aware of. . .

 

Tier 1 phone support isn't helpful.  Hoping this forum can help me resolve.  I'm a first time poster so not sure if I should be posting photos but will do so on request.  Thanks!

Share the modem's signal stats as well.

 

Please post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.

Is this with a WiFi connection ?
