Frequent T3 Timeouts and disconnecting

Like apparently several posters in here, we are experiencing increasingly regular T3 Timeouts. It was about once per week, usually around 9:15 pm. Then it was once per day. It has now become every night and every morning with multiple Timeouts about every 30-45 min after 9:30 am.

Whoever moderates this can conclude that there is "noise" somewhere and elevate this to the next level. Here's some of the info I've captured recently below. Formatting won't be great because I have to post this from my phone, because... you know I don't have internet from Xfinity to my computer...

Re: Frequent T3 Timeouts and disconnecting

Cable Modem is Motorola SB6141. Router is irrelevant, but Asus RT-AC56R.
