It depends on the model of your TV. If you have a UN or LNxxBxxx, then yes, you can use the same adapter for both. If you have a LNxxAxxx, then you cannot swap back and forth.
Hope that helps.
I purchased and successfully installed the Samsung Wireless LAN adapter for my new 46 LED. However, I see little value in Info Link on the TV.
Can you swap the adapter back and forth between the TV and my new Samsung Blue Ray BD-P1600? Or, would I need a separate one for each unit?
