If you read through the reviews @ Amazon, I believe folks have reported it to be a substitute for the other model you list above. YMMV. Seems cheap enough though, that you could simply return to Amazon if not.
I have a Samsung LN55C750R2F and I want to be able to use it online. The manual says I need wireless LAN adapter (WIS09ABGN, WIS09ABGN2, WIS10ABGN).
I can't find any of those. The only one I have found is WIS12ABGNX. Will this model number allow me to get online and work the same as the suggested model, or am I going to have to keep looking until I find somewhere that has the model that my tv manual lists?
