Fn button broken

I need to hit Fn + F2 to turn on my internal wireless card but Fn is broken. Does anyone know another way? Or maybe a way to activate the Fn key without the keyboard?

 

Try remapping the key to another key with software.

Or go to your bios, and sometimes you can change your Fn key to ctrl or alt. But this way means that your alt/ctrl key will stop working But you could do this to find the code for your fn key first and input it to your software. Cos sometimes those key mapping software needs you to input the right code or at least press the button.
