To prevent Firmware upgrade failure, a user is advised to connect the computer to the router using a wired connection. A wired connection avoids the sudden disconnection while uploading the firmware to the router. You must keep the downloaded firmware in a location from where you can easily access it during the upload process. You can upload the firmware in the router using the setup.ampedwireless.com interface. Make sure you extract the downloaded firmware file before the upload process using decompression software like WinZip or WinRAR.
