You cannot manually update your NETGEAR cable modem or modem router’s firmware, unless you have a CAX-series cable modem router or CBR-series cable Orbi router. CAX-series and CBR-series cable modem routers use separate router firmware and cable firmware. For more information, see How do I update the firmware on my CAX-series cable modem router or CBR-series cable Orbi router?
NETGEAR provides your ISP with the latest firmware and your ISP updates your firmware. If your firmware is out of date, contact your Internet service provider (ISP) for assistance.
The following table displays the latest firmware versions of NETGEAR cable modems and modem routers.
If your ISP is not listed in the following tables, advise your ISP to contact our sales engineering team using the following contact form: https://www.netgear.com/about/contact-us/cable-mso.
