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
