Difference between WIS09ABGN & WIS09ABGN2(AK96-01194A)
I got an answer about WIS09ABGN2 USB dongle issues from Samsung tech supports.
There are difference between 2 dongles.
-WIS09ABGN: compatible with select Samsung TV & Blu-Ray models
-WIS09ABGN2: compatible with select Samsung Blu-Ray only.
So, if you want to use USB dongle with your TV, you can return it for credit & place new order with WIS09ABGN.
