c7000v2 dropping connection regularly Xfinity

Hello, I'm looking for some insight on the possible cause of my internet dropping multiple times per day. Sometimes it's for a couple seconds, others times it's for a minute or 2. I'm not sure if the issue is my modem or I have line issues. I'm using the Nighthawk c7000v2 with Xfinity. When I moved into the home about 6 months ago, Xfinity came out and ran new lines to my modem and tv box (previous owners had dish and everything was goofy). For the first couple months I don't recall many issues, but the last few have been pretty bad and only seems to be getting worse. I've reset everything a couple times and Xfinity has done all of the troubleshooting/resetting on their end as well to no avail. 

Before I pay for them to come back out, I was wondering if anyone could review these logs and let me know if there's anything obvious issues. 

Thanks!
