Manually upgrading your Linksys Wi-Fi Router's firmware

Firmware updates are bug fixes and functionality enhancements for the router.  Keeping the firmware of your Linksys device updated is important because it fixes issues you may encounter while using it.  An updated firmware downloaded from the Linksys Support site may also contain device feature enhancements that are not available in the previous versions.  

Your router is capable of either an automatic or manual firmware upgrade.  This article will show you steps on how to manually upgrade your Linksys Wi-Fi Router's firmware.  If you are using a Linksys Smart Wi-Fi Router, click here for instructions.
IMPORTANT:  To prevent upgrade failures, the following items must be checked before proceeding with the upgrade process.
  • Use a wired computer for stable connectivity.  It is NOT recommended to update the firmware via Wi-Fi as it may cause permanent damage to the router.
  • Use another browser if your default browser does not work.  Alternatively, you can use another computer to perform the upgrade.
  • Download the correct firmware and version for your device.
  • If you have a storage device connected to the router, make sure to remove it before upgrading the router’s firmware to prevent data loss.
  • Make sure that you have created a backup configuration.  For instructions on how to create a backup, click here.

Checking the model and version of your router

You should find the model number and serial number on the router's label at the bottom.
