At least where I live, the key is to have a modem that does not support the latest DOCSIS standard the ISP claims to have supported. They basically never get the implementation of the latest thing correct, so you don't want to wind up using it. I have the option to bring my own modem, so I just get a cheaper and slightly older modem and use that.

The prevailing issue is the way the US regulates ISPs leading to a lack of competition, giving them little incentive to do anything other than raise prices on a regular basis. While I have at least talked to technical support people who understand the concept of a cable modem being supported or not, there is no one available you can talk to who understands signal levels, etc. The only diagnostic they can perform is "does speedtest show the advertised speeds".

There is still some sort of issue with the cable modem getting "stuck" in a bad state. I have a USB controlled relay that is used each morning to interrupt the DC power to the cable modem. This basically fixes it. I'm not awake when the modem resets so it is a non issue to me.

Yes but the key is to have an ISP that [is forced to] allows you to get your own modem. Also most of the world is on DOCSIS 3.0, so any older than that is DOCSIS 2.0 which would be max 50 Mbps which is not ... nice, and that's DSL territory (VDSL2 does up to 100/30 Mbps).

Being able to use your own modem would fix a lot of problems I have with DOCSIS ISPs, but sadly there's no regulation for it. So yeah, you have to use theirs.
