You can't manually update your NETGEAR cable modem routers firmware

Why don't they want you doing this on your own. We can screw up software/ hardware in so many different ways what's the problem with allowing one more. My firmware is sitting at V2.01.26 while the Co...

The latest Cox-approved version of firmware available for this modem is 2.05.18, which is what you currently have. Customers are not able to upgrade firmware on modems as that comes from whichever provider the modem is connecting to. If you have your own stand-alone router, you would be able to upgrade the firmware on that, but not a modem.

Thanks for replying. Your right. Netgear Genie says V2.05.18 not what I wrote  V2.01.26. I have a Netgear Gateway C6300BD. It is a combo modem/ router that I bought from Cox. It is not a rental. Why does this page indicate that the latest Cox approved firmware is V3.01.09 for the C6300 Cable Modem Router and not the old 2.05.18 which I have and you indicate is the latest approved. So if this is a combo modem/ router that I own bottom line are you saying I am unable to update the firmware? Thank you.

    I'm not sure why they have V3.01.09 listed there, V2.05.18 is the latest that we offer. They might be trying to say that they have approved us to use that version, but we do not currently offer that version on our cable plant. You would not be able to upgrade the firmware on your own even if you owned a combo modem. I meant that if you had a stand-alone wireless router that was connected to a stand-alone modem, you would be able to upgrade the firmware of the router. Even with a stand-alone modem, the firmware for the modem is still updated by the ISP not the customer.

      Thanks again for the info. If in fact version 3.xxx has been approved that is quite a jump up from the old version. I think this modem/ router is at least a half dozen years old and obviously the firmware has never been flashed. Do you suppose you can elevate this question and or ask around why if a later version may have been approved we are still stuck on 6 year old firmware. Thank you.

        Hi Harmony1973, we currently do not have this information readily available. Prior to releasing new firmware for third-party equipment, Cox has to adequately test the features to ensure that there are no bugs, performance issues, and that it meets the safety and security requirements. -Kevin M.
