Function key emulator for Dell inspiron 6400 on external keyboard

Question

I have a 3 year old Dell inspiron 6400 with windows 7 and ubuntu 9.10 dual boot.

I messed up my laptop keyboard and hence my Fn key is not working and I need it to activate the wireless whose activation combination is Fn+F2.

Is there any way I can emulate the Fn key or get my wireless to start in windows or Ubuntu? My BIOS has an option for Fn key emulation but that only supports external PS/2 keyboards and my laptop doesn't have a ps/2 slot.

Solution

I know this is late to the party, but for Dell laptops and external KBs (as well as others I am sure) the scrollLock key sends the Fn key signal. Unfortunately for all brands this information is "hidden" where it should be broadcast.

I had already tried that ! None of the Fn combinations work.

perhaps fn is always on in bios, try just pressing f2. its a longshot but
