Although I cant say if that hotspot device will work since I do not have the device to test my self, I can say that if the hotspot device allows for other devices to connect to it (similar to a wifi router); then, with the WIS09ABGN wireless linkstick, you should be able to connect the blu-ray player to the hot spot device and access Netflix. I would suggest doing a little more research into the hotspot device and see if anyone has had an issue with prolonged connections or even security settings, as this may hinder your netflix viewing.
I've read alot of forums and just want to clarify compatibility.
