I have a N600 WiFi cable modem Router and I cannot update its firmware. I went to advanced-Administration and there isn't an option. The firmware is way outdated but I cannot update it! How can I update it? Also, I want to disable IPv6 as I understand it will help with a Chrome/Facebook issue where my cpu goes to 100% and the feed won't load. How do I do that?

Am unsure whether issue remains unresolved, as original post and comments are somewhat dated, but am sharing my experience that may be of benefit... Similarly have C3700 unit (originally purchased with OEM firmware V1.01.11) which has been upgraded to current V2.02.08 by Comcast xfinity ISP. As DarrenM has commented below, Netgear cannot directly upgrade firmware (and does not provide means for customer to upgrade firmware themselves) -- firmware version is controlled entirely by ISP. That said, for Comcast xfinity ISP, contacting their general technical support line is generally useless, as likely you will be connected to offshore call center whose operators have little to no technical expertise and simply regurgitating call script. Instead, directly contact Comcast Tier 2/3 Advanced Repair Dept in Denver, CO (higher level support that call centers eventually escalate to) -- their direct phone number is: 800-718-7419 True, as has been commented on other related posts, Comcast xfinity ISP cannot manually "force" firmware updates, as firmware updates are automatically controlled by their system infrastructure. Instead, what they can do, specifically have them re-provision your cable modem, which as part of provisioning process of identifying and connecting hardware credentials to your account, it will determine your modem's firmware version and download update if necessary. Note, as indicated above, as of date, V2.02.08 is current firmware version, however, currently have open Netgear Support ticket (see post: https://community.netgear.com/t5/Cable-Modems-Routers/embedded-web-interface-fails-after-week-runtime/m-p/1329401#M9437) in which Netgear has identified firmware flaw in that current version as root-cause of failing embedded web interface known issue, and is supposed to release firmware fix sometime.

And how do we get updates for ISP's that are not listed, for routers purchased from a retail outlet by the end user? Seems highly inappropriate to sell a product that netgear wont support unless its acquired through an ISP.

fireman5864 thank you for posting the email. We are surprised that Spectrum (AKA TimeWarner, AKA Charter) is spreading such mis-information. This case has been escalated to Spectrum's management and we will let them deal with it. Spectrum is extremely difficult to communicate with and they are "extremely" slow when it comes to FW upgrades even though NETGEAR pays them thousands of dollars in FW certification fees practically every month. I am sure other vendors have same problem with Spectrum. if you were on Comcast Xfintiy's network, you get FW upgrades pretty much 2-3 weeks within FW certification period (it could be much faster in some cases as well). It is very unfortunate you have to live with spectrum. NTGR will attempt to reach out spectrum again to get confirmation but we are not sure if spectrum's response will be favourable.

StartboardBowThanks for your reply, but the firmware that Spectrum allows us to have doesn't imply that is safe for our router, or that our router is immune from Krack WPA2 issue. It's old and it's overwhelming not to have the possibility to choose the firmware we should have, the day Netgear will come out with the fix, if that they will ever come for older router like ours.:mansad:

  How do I go about getting them to get off their butts and update me to the latest version? They are way behind.

    Wow I can't believe there is still so little communication and or understanding between the ISP and modem manufacturers!!
    
    I am having Comcast installation in a couple days, I hope I don't have the same issues I had with WOW and if so I hope I can get through to someone that can get it updated. No one at WOW could.
    
    If not, I will have to buy a new modem and router, and I know for sure it will not be a Netgear since they are clearly not interested in fixing this disconnect between them and ISPs to improve the customers' experience.

    What did you do exactly to update it?
    I have C3700 100NAS as well and my ISP is Spectrum - firmware version is V2.02.08
    I'm worried about the Krack WPA2 and they dont seem to care about
