Version 2 adapter. No problem. I recommend to buy. Has pros: Used in conjunction with TP-LINK TL-WR841ND for 3 months. The signal is strong, there are no failures. The adapter does not ask for anything, it does not heat up, it is not noticeable. With its cons. Sometimes when you turn on the computer, the adapter does not turn on, and the control LED on the case does not light up either. It starts when the USB cable is twitched. I think my old computer is to blame, not the adapter.
