About router firmware:

Before considering downloading this firmware, please go to the router’s system information page and make sure that the currently installed version is not a newer version or a version that matches the release.

As there are many types of routers and different methods to upgrade devices, it is strongly recommended that you read and understand the installation steps first. Even if you are a super user, you can apply the new firmware.

In theory, these steps will not be too much trouble for anyone, because manufacturers try to make them as simple as possible, even if they are not always successful. Basically, you must upload the new firmware to the router through its management page and allow it to be upgraded.

If you install a new version, you can expect to increase the security level, solve different vulnerabilities, improve overall performance and transmission speed, enhance compatibility with other devices, increase support for newly developed technologies, and many other changes.

If you are looking for some security measures, remember that it is better to use an Ethernet cable instead of a wireless connection to perform the upload, as this can easily be interrupted. In addition, if you want to avoid any malfunctions, please make sure not to turn off the router or use its buttons during the installation process.

If this firmware meets your current needs, please obtain the required version and apply it to the router unit; if not, please visit our website as often as possible to ensure that you do not miss an update that can improve your device.
