Cable modem restart every few minutes and cause internet disconnection. Help needed! - Time Warner Internet

#1
This question is about "Cable modem restart every few minutes and cause internet disconnection. Help needed!", with Time Warner Cable internet and apps. Hi,

I suffered internet disconnection caused by cable modem reboot or malfunction. It happened every few hour or feww days. I tried contact technical service and on-site check. They all failed to find the root cause. I will post cable model log and hope there is a solution without switching modem. Thanks.



Setting:

1. Sepctrum internet.

2. Motorola MB7420

3. ASUS AC 1300
