Random Connectivity Errors Probably T3 timeout related on sb6183 modem - Time Warner

This question is about "Random Connectivity Errors Probably T3 timeout related on sb6183 modem", with Time Warner Cable internet and apps. Hi All,

I am having sporatic connectivity errors with my sb6183 modem. I recently had twc tech come out and they ran new lines through the house, but I am still having random connectivity issues where I believe the modem will restart on it's own. I am not 100% sure what is causing the issue.

Here are the event logs that I have:
