Need assistance decoding CM1000 logs please!

Good afternoon... for some reason, my posts keep getting deleted/rejected.  Not sure why. :(  I am having issues maintaining a solid internet connection on a CM1000 wiht XFinity cable, and drops intermittently throughout the day.  Could you please take a look at these logs below, and let me know if in your opinion, this is an XFinity line connectivity/upstream issue, or if this is typical behavior of one of these units going back?  It's much appreciated!
