Vista - How to activate the wireless adapter

Hi everyone!
Firsto of all i'm sorry for my bad english!! I hope I can explain myself well enough to make you understand what's my problem!

I have a notebook Fujitsu Siemens Amilo A1655G, and i've installed Vista Ultimatex64! I know that officially my notebook doesn't support this OS, but I wanted to try it! All seems to work fine except 2 things...
1) My touchpad works fine for 1 minute and then it stops, and I can only reboot the PC or use the mouse
2) The biggest problem a.k.a. how to activate the wireless adapter! Under XP I've only to press a button and it works correctly, but under Vista it doesn't seem to work properly... well it doesn't seems to work at all!! The wireless is a broadcom 4318, and I know it can be activated also via software but I really don't know how to do it! I've passed the last 2 days looking for the solution but I haven't found nothing usefull...

Hope someone can help me!

Thank's a lot!

If it's activated by something like a Function button, you'll most likely need to go to the website of the company that built your laptop and download the drivers for it. The same might apply for your touchpad situation, too. I had the same problem when I had to reinstall my OS for my VAIO, once I got the right driver, the function keys started working again.
