Repeat disconnects with Motorola SB6141

I recently started using Cox Internet using my own personal Motorola SB6141 modem. Previously I was using this modem with Comcast/Xfinity for over a year with no issues, but with Cox I've started to have problems. The connection to the internet won't re-connect until I unplug/plug-in my modem.

Cox sent technicians out and they changed the line and added a 3db attenuator between the wall jack and my modem but that didn't solve the issue. I switched my router to a Netgear R6400 but that didn't make a difference either.

I don't understand the signal data or log data from my modem so I'm hoping someone here can make sense of it.

Modem firmware is: SB_KOMODO-1.0.6.14-SCM01-NOSH
