    Well, it looks like it was that butt connector... or perhaps just needing to also clean and tighten the ISP side.

     

    First, I connected the ISP cable directly to the modem outside and plugged the ethernet into a laptop.  Accessed the GUI and correctables and uncorrectables were 0.  So, I installed a fresh new splitter out there to the cable that runs to the network closet and tested similarly in there and success, errors still 0, so my cable is good.  Phew.

     

    So, I then reconnected CM700 modem output ethernet to the router to restore my network and everything is working...  EXCEPT I can no longer log onto the modem GUI to check or monitor this going forward.  On any device, wired or wifi. On any browser. I just get "can't reach page, took too long to respond" errors.  Just like it had been for weeks lately until somehow miraculously I started being able to logon this morning.  But that is just gone again?  I really don't understand what is blocking me from reaching the modem admin GUI.
