CM600 firmware not upgraded by Time Warner Cable

NO CABLE MODEM MANUFACTURER CAN UPDATE FIRMWARE.

This is the biggest reason to not have a Modem/Router Combo! If your ISP refuses to update firmware, they think it will not solve any problem, you should rent a modem or deal with out of date firmware and whatever performance or security issues that entails.

ONLY THE ISP can provide Firmware updates as has been said many times! ISPs will not let untested firmware run on their network, otherwise it would be easy to spoof and steal service or remove speed caps in config files. Most L1 tech support do not know the difference between a modem and a router, the L1 tech I got today said that they did not update firmware on customer owned equipment, I asked to talk to L2 or a supervisor, and the tech said he wasn't lying to me. I replied that I didn't think he was, but that he had bad information. He put me on hold and called L2 support and came back a few minutes later saying that L2 would help me with getting a new firmware pushed to my modem. A few minutes later the update was on it's way.

I was running 1.01.05 out of the box, purchased in March 2018 from Amazon. Netgear support website says that Cox has approved 1.01.14. After the L2 tech pushed the update and the modem came back online I went to the Modem IP and now I am on version 1.01.12. Until Cox decides to push 1.01.14, there is nothing I can do to update. Maybe persistance will let you talk to the right tech to get the updates pushed, you have to talk to the technical expert support, not the guys working with scripts and call quotas.

Any tech who claims that Netgear can update the firmware is lying or misinformed if it is a modem approved by the ISP.

I didn't even need to contact Netgear support becuase I've read threads like this on every modem manufacturer webpage, customers who do not understand that the manufacturer cannot update firmware on Cable modems need to just rent a modem and be done with it.
