Xfinity Connection Dropping Intermittently

Hello,

For the past month or so, I have been having issues of my connection dropping intermittently. I was orignally running a Netgear C6250 modem/router. I was getting T3/T4 errors at least a few times a day and sometimes almost every half hour. The modem resets after this and takes ~5-10 minutes to get back up. I reduced the houside Coax to just a butt connector to the Comcast drop, and this did not help the issue. It appeared that the Upstream values would spike.

 

I then purchased a new modem/router to see if it would help the issue with more channels. It has not helped at all. I am currently running an Arris Surfboard Model SVG2482C. It does not allow me to see what kind of errors I am getting. It just gives me [Dhcpc][20042]: erouter0 got new IP event logs at the same frequency of the Netgear router.

 

I have tried contacting Comcast to get a technician out, but it seems all but impossible. I just get the run around from the representative and they try to reboot the router and tell me everything is fine. Thank you for any help you can provide!

 

Here is the current information on the network connection, this is while the connection is live:
