[Ubuntu 11] WLAN deactivation

[MoonKid]

I have a Samsung N220.

I tried the current Ubuntu 11 from USB-Stick as a Live System. The Fn-keys for light and volume work out of the box.
But I am not able to deactivate the WLAN adapter with the Fn key.

Any ideas?

I don't want to install Ubuntu before I know that my N220 fn-keys are supported.

It works with 11.10 and the samsung-tools package.
