So for what it's worth after modem upgrade, but no more dropped signal and hard modem resets required. At least for the past 3 hours or so of new modem use.
So the patched ass setup I had wasn't doing it for me, so swapped out broadband modem again aNd rechecked speed (gonna do it on the regular and contact Crapcast to determine tier) and here we are now at 9:30PM.
Before
was 11mps/11mps and 21ms
After
Noticeable increase in page refresh and speed from the eye dyno.
