T3 time-out - Time Warner Internet

This question is about "T3 time-out", with Time Warner Cable internet and apps. Hello,
I've been experience my connection dropping a lot recently. Each time, the Event Log reads, "Started Unicast Maintenance Ranging - No Response received - T3 time-out;CM-MAC=00:8e:f2:3a:dc:78;CMTS-MAC=00:01:5c:64:92:5a;CM-QOS=1.1;CM-VER=3.0; ".
The problem seems to be random and happens several times per day.

Location: Newark Valley, NY, 13811. Single-family residence.
Service: 30 Mbps Internet
Modem: Netgear CG3000D-RG Modem/Router combo
Firmware: 1.04A
Software: V5.5.3.mp1CPR07c
Modem is online.
Speed Test: 27.34 Mbps down, 5.91 Mbps up, 25 ms Latency, 9 ms Jitter
Signal/Power Levels: https://i.gyazo.com/ba8c0178f02024e420950b87acb263e4.png
Event Log: https://i.gyazo.com/52528a82943a4e8db49f4a2ffc2304b3.png
Wiring: Street to Splitter, Splitter to telephone modem and 2nd Splitter, 2nd Splitter to Modem.

Any idea what's causing this or what I can do about it?

Thank you!
