John,
   When we had a customer-owned Motorola Sharkfin-style modem, which was either Docsis 1.0 or pre-Docsis, Charter Communications dba Spectrum started deliberately screwing with the connection;  It would go down about once a day, right around like 8PM or midnight, and you would have to powercycle it and it would work.  Finally called them, they wanted us to upgrade to one of their cable modems, which they provide for "free".  Didn't send an email or a letter like a normal company would but forced you to call them!!

In our area they give you a www.hitrontech.com Docsys 3.1 eMTA EN2251 PC15 modem with two telephone connectors and a theoretical battery-backup connector (does anybody use the battery backup or have their cablemodem on a UPS?  Does it even work?)  It's physically way larger than it should be.  All web pages, configuration, logs are disabled so the customer cannot troubleshoot anything themselves.  Can log in to your MySpectrum app and "check the connection" which sometimes can wake the thing up when it is disconnected.

I've read on the internetzzz that you can have problems such as failing analog amplifiers in their cable plant cause hard to diagnose intermittent problems, and also that Docsis 3.1 is more sensitive to line quality than Docsis 3.0.  My biggest concerns include the rising price of their internet service.
