A user performing the Firmware update manually has to take care of a few things carefully. While downloading new firmware, you have to make sure that you are using the correct hardware and model version of the router. An incorrect firmware may corrupt the software of the router and may void its warranty. You can check for a correct hardware version on the back of your router or on the label of the box in which your router came. New models of Linksys routers automatically update the firmware in the linksyssmartwifi.com interface.
