I just wanted to post a quick note for anyone looking for a new vs old Tenda Homeplug. Originally it appeared that the box alone was a good indicator. This is not the case anymore. We just received some Tendas from newegg that have the new box but the old adapters. The reset button is the key indicator that shows you have a new circuit board that pulls apart easily and works with our new topside adapter board.
Have a good one,
