Spontaneous Internet Disconnects

edit

• Everyone in the house is complaining about it, so I've ruled out my PC.
  • Replacing a coax cable from the wall to the modem "appeared" to make a noticeable difference, the time between disconnects continued increasing. A few days passed without 1 issue that I know of, and then slowly started to come back, though still much less frequent.
• I was able to log the event and there appears to be a ton of colored messages within a span of 2 minutes or so. I'm trying to decipher them but could definitely use some help.

I have a Netgear Nighthawk R6400 Router and a Motorola/Arris SB 6141 Modem. WS Log attached below via G Drive (is there a better way to upload files?)
