Linksys periodically publishes new firmware in the router to add new features and to fix certain issues in your router. A user can directly update the firmware of his Linksys router through the linksyssmartwifi.com interface. You can directly check the availability of a new firmware through the home page of the Linksys router. A user is just a single tap away from updating the firmware of his Linksys Router. A user is advised not to turn off his router, avoid opening a new webpage, avoid closing off the current browser, and avoid clicking the hyperlinks of a current browser to avoid the interruption in the update process.
