This topic is important because it lead us to use any USB dongle on our TV's.
I wanted to know that any one tried to compile samsung TV kernel from their sources?
I tried once with cross-arm but I failed. I don't know error message exactly. Could you try too?
(If you don't understand what I am talking about or don't know compiling linux kernel well, forget it

If you cannot compile whole kernel but modules, It's okey too.
Required tools are cross-arm compiling tools and source codes from Samsung

You have to know that '32B650.zip' files WiFi drivers are removed. You can found them at 'LE40B650T2P.zip' file.
Good Luck!
