What are we supposed to do when ISP's say they don't update customer-owned modems (CM500)?
FURRYe38 What are we supposed to do when ISP's say they don't update customer-owned modems (CM500)? I've supplied my own to avoid the rentals fees and they say to reach out to Netgear...

A couple of additional pieces of information.
The CM500 is a DOCSIS 3.0 device. There is a chance your ISP no longer supports these older devices. Is the CM500 on the official list of customer owned and maintained devices supported by your ISP? It may have been at one time, is it still supported today?
The CM500 is on the official Netgear End of Service list here: https://www.netgear.com/about/eos/.
The Netgear support web site does not show any "Downloads" for the CM500. Nor does the User Manual mention anything about firmware updates. The Product Data Sheet claims the CM500 is compatible with the major cable providers:
Like you, my assumption has been that once the modem is connected to the cable provider, they are entirely "in charge" of it. (setting parameters, maintaining firmware, etc.)
- How have you determined that this modem requires a firmware update?
- Which ISP is this?
Just going by their site, mine is currently on 1.05. Since Optimum "no longer allows" DOCSIS 3.0, I'm not putting any more effort in getting it updated. Plus, it's working fine so an update is not critical.

Enjoy.
FYI, C, CM and CAX series model modems/gateways don't have any user FW updates available. Been like this for a long time. All modems and gateways with modems and routers, the modem side is all updated by the ISP, if and when they choose too. The CAX series has a router side that is updatable by users. However the modem side is still updated by the ISP only.
The CM500 is a fairly older cable modem and though was certififed back then to work on most ISPs that supported it, ISPs can of there choose to stop supporting older model modems as technology and DOCSIS specs and ISP infrastructure make inprovments over time. Users will need to check with the ISPs to ensure modems they are actually supported on there network services.
Good Luck.
ISPs control all of that. ISP handle there policies of updating FW and can choose to update user owned modems or not.
If they don't, then recommend using one of there modems and connecting your own external wifi router system to it and you can manage that.
