use extender to convert wireless to cable

[extweem]

Is it possible to use something like this http://maxxter.biz/item.aspx?id=7922&lang=nl to convert a wirless signal in my house to a RJ45 cable.

I need an internet connection for digital television in another room but i dont have cable there. So i want to be able to connect somthing to my wifi where i can plug in a rj45 cause the digital tv doesnt have wifi.

Yes if the signal is strong enough it should work.
