NETGEAR strongly recommends that you download the latest firmware as soon as possible.
To download the latest firmware for your NETGEAR product:
- Visit NETGEAR Support.
- Start typing your model number in the search box, then select your model from the drop-down menu as soon as it appears.
If you do not see a drop-down menu, make sure that you entered your model number correctly, or select a product category to browse for your product model. - Click Downloads.

- Click Release Notes.
- Follow the instructions in the firmware release notes to download and install the new firmware.
Security Hotfixes
Security hotfixes are fixes that are applied on top of existing, fully tested firmware. Releasing hotfixes allows NETGEAR to quickly update existing products and streamline the firmware verification process without going through full regression testing. These hotfixes are targeted at specific security issues and should have minimal effect on other areas of the product’s code. Therefore, we do not expect that installing the hotfix will affect the regular operation of your product. Although our pre-deployment testing process did not indicate that these hotfixes would affect device operability, because full regression testing is reserved for final production firmware fixes, we always encourage our users to monitor their devices closely after installing a firmware hotfix.
