Most adapters require a driver in order to work. Since there's no way to load 3rd party drivers into the television, the LinkStick is the only USB device that I know of that works.
The good news is that since only one works, we've been able to streamline support issues, so if you do run into a problem, we can help get you connected easier, too.
I just purchased a UN55b8000 and want to hookup the wifi to utilize all of the internet features on the TV.
Can you use any USB wifi adapter on these TV's or do you have to have the Samsung WIS09ABGN adapter? I purchased Samsungs adapter but at a premium cost and if I could use any wifi adapter I would return this in a second.
