Connectivity problem: SB6141 modem randomly dropping connection - Time Warner Internet

#1
This question is about "Connectivity problem: SB6141 modem randomly dropping connection", with Time Warner Cable internet and apps. Hi all! I have my own Arris SURFboard SB6141 that sporadically and randomly drops (new problem, began a few months ago). I have no idea how to read the logs, troubleshooting with Spectrum hasn't gone anywhere. Help?
