      Not sure this is related, but my download speeds were capped out at 450 mbps, never above it.  When I put in new cable modem, T25, it ran the same speeds,  Today, over 600 mbps download.  Not complaining, but leads me to suspect ISP is changing things on their end.  Could be pushing some modems to fail?

        Does anyone know what firmware the CM1150V ships with?

        I didn't take note of it when I installed last week 

        Now is V4.02.02 

        I'm wondering if Xfinity has pushed an update recently which may have coincided with the first modem issues, and now with the new modem?
