I've been very particular about using my own router and/or wifi in the past, installing one of openwrt/dd-wrt/tomato and tweaking to my heart's content. I would create a DMZ for one or more servers, do the dynamic DHCP, the whole bit.

But now, the ISP provides a single device that is where they terminate the DOCSIS connection and originate the Wifi router. And casual investigation leads me to believe that I "can't" replace this device. I don't want/need a DMZ or my own public servers. Also, I have less patience for tracking down my own breakage these days. The ISP's device works and performs spectacularly. I know of no public vulnerabilities for the provided router.

So IMO no I don't "really want to get rid of any kind of ISP provided router and Wifi".

You can purchase a modem as a separate device that you could then use with any router. It could save you some money depending on whether or not your ISP charges you for renting their hardware.

Hmm, no idea for your ISP, but most of the ISPs I've used had the option to switch their equipment to so-called "bridge mode", where it just did the DOCSIS/DSL thing, gave you one unfirewalled external IP and let your router do NAT etc.

They usually didn't advertise that though.
