Intermittent Internet Disconnections

Hi All,

 

I am on an internet only plan, and the internet keeps going out. From what I can tell the cable modem keeps restarting. I've also confirmed there are no splits between the cable modem and the  incoming cable, and checked snugness on the connections. 

 

I dont know if this could be a signal strength issue or a modem compatibility issue.  

 

I've included modem specs, signal status. and error log below. Any help here would be appreciated. 

 

 

 

Cable Modem:

Netgear CM700
