The WIS09ABGN can connect to either your model of TV OR the Blu-Ray player. Unfortunately, one LinkStick will not connect to both units simultaneously. But you can swap them back and forth, depending on what you'd like to do, if that provides a solution.
Hope that helps.
I was wondering if I need to purchase two wis09abgn dongles, or if connecting the wireless adapter to my PN50B850 would also connect the BD-P1600 blu-ray player to the network thru the HDMI cable?
