Just got a RT-N66U. Firmware version .90. Multiple times trying (wired and wireless) to update firmware to .112 and always at 67% it stops and says "No Internet connection is detected. The router cannot connect to ASUS server to check for the firmware update. After reconnecting to the Internet, go back to this page and click Check to check for the latest firmware updates." Have also tried the browse with firmware downloaded from ASUS and it says "Firmware upgrade fail. It may result from incorrect image or error transmission. Please check the firmware version of firmware and try again." Is it something I am doing wrong or does it sound like a problem with the router. Please let me know if there is any other method to upgrade the firmware.
