Once the router and your computer are connected, open a web browser on your computer.
Visit the router manufacturer’s website to download the recent version of the router firmware.
Now, open a new tab on the browser to visit the router login page.
Enter the router login credentials and log into the admin panel. Click on “Firmware”.
Upload the downloaded file and click on OK to complete the router firmware update.
