Frequent Internet dropouts, all about 2 minutes each. - Time Warner Internet

#1
This question is about "Frequent Internet dropouts, all about 2 minutes each.", with Time Warner Cable internet and apps. This problem relates to the connectivity of my Arris SB6141 cable modem and has no relevance to the standalone router home network. For about the past three weeks, we've had frequent and consistent loss of the Internet for periods of about 2 minutes or less. During these outages, the cable modem shows only the power LED on, the rest go dark, and then sequentially come back on once connectivity is restored. Here's a log for outages between July 10 and today, except for a couple of days when we were out of town:

A Web search for others with a similar problem turned up information from other providers' user groups, some of which are populated by users who must really be into this stuff. I am not, but have put a PDF copy of the info dump and logs from my Arris modem up on Dropbox, hoping that maybe someone monitoring this forum can provide some insight into what may be going on.

Any help is appreciated; I'd really like to have a handle on this before having someone from Spectrum come out and take a look. Many thanks!

Frequent Internet dropouts, all about 2 minutes each.?
