Notebook keyboard failure

Hey all,

I need to know if there is anyway to "turn on" the wireless LAN on my NEC
versa E680 Notebook running windows XP professional without using the Fn+F1
key combination.

The keyboard on my notebook has failed and so I am now using an external USB
keyboard which does not have an "Fn" key. After my last restart windows
booted with the wireless LAN switched off. To switch it on I need to hold
the Fn key and press F1 (which is now impossible).

Any ideas?
