I am also having issues setting up WDTV Live to work with WN821N adapter. Mine is Version 3.1
WDTV Live is Firmware Ver 1.04.22_V
When I connect the USB Adapter I do NOT get the Wired or Wireless setup options. The power / connection light on the Adapter does not light up either. I am trying to connect to a TP-Link TL-WA901ND Wireless Access Point.
I have tried everything I can think of. Powering on the WDTV Live with and without the USB adapter connected.
I have tried disabling all security on the WAP.
I have tried the automatic connection method of pressing the QSS button on the WAP and the USB adapter. This did work when I had the USB adapter connected to a laptop and the QSS software was installed. This has also confirmed that the WAP and USB adapter do work together, just not when connected to the WDTV Live.
Can anyone advise how to get the USB adapter working.
