Its important that your adaptors have the same revision / version number as the tested item. If you have different number then the manufacturer may have changed the internal chipset to one that is not supported by the WD firmware.
You must also have the latest firmware on the WDTV.
I bought the WD Live TV Plus (firm ware is the latest as of 5/22/2011) and seems to be recognizing my AirLinkLL5077 wireless USB (which is the first option on your compatibility list and which others have gotten to work).
HOWEVER, as soon as I enter my wireless network’s password, the WD then no longer recognizes the network. At times I can put in the wireless network password, only to be submitted and upon return, the screen doesn’t recognize anything. The device connects physically to the network, but this is not possible with the set-up in my living room.
