There are other ways to get WiFi to the TV. But first, that model does not look to be a smart TV. This IMO is a waste of time and money.
Go get a Roku.
I have a Samsung TV LN55C650L1FXZA. The manual indicates to use WIS09ABGN. Samsung no longer carries it and suggested I may find one online. MY search has left me confused......does the Wis12ABGNX replace the WIS09abgn? And can I use something "compatible to WIS09abgn and WIS12ABGNX" that is not Samsung? I would like to be able to use Netflix. Thanks for your help!
