@Krazyraj 

 

May I have the hardware version of your WR840N, is it V5? How about the region version, is it a US version or an EU one?

 

Which firmware are you trying to install on the device? Please be aware that you are not allowed to install a firmware version that has been made for another hardware version of your router model. If your WR840N is indeed hardware version V5 then you can only install firmware made for hardware version V5 and not firmware made for V6.
