T3/T4 Timeouts and reboots - Time Warner Internet

#1
This question is about "T3/T4 Timeouts and reboots", with Time Warner Cable internet and apps. Hello, in Chapel Hill, NC, using SB6141, 100/10 service. Started getting lots of intermittent drop outs & reboots (several a day sometimes). Here are signals & logs & build:

The 1st channel looks wonky to me: SNR 29 vs 33-36 and the correctable codewords are off the chart.

House is wired with RG-59, and likely splitters. Tech a few years back thought I might have trouble at 50M or higher, though when modem works I get close to 120 down. Had a new RG6 line run a couple years ago when I installed CAT5 wiring but never had TWC hook it up since everything was working ok. So switching modem to this line is an option.

BTW, ATT planted fiber in the neighborhood in the past year and just rolled out their service. Coincidence?

Should I ask for a service call? L3? Other?

TIA, Jim
