This article explains how to update your router's firmware and why it's important. Every router is different, but there's usually a similar process for performing upgrades. Check your router manufacturer's website for a user manual with specific instructions for your make and model.

To update your router's firmware, follow these steps:

Download the firmware file from a trusted source. Ideally, you would get the firmware directly from the manufacturer's website. For example, if you were upgrading the firmware on a Linksys E1000 router, you would visit the download page on the Linksys website to download the firmware.

Log in to the router's management console.
