AirPort card not working?

Hi,

I just opened my new Mac about an hour ago and I found out I couldn't connect to the internet (I was running Vista via BootCamp) so I decided to restart it to Mac OS Leopard and when I logged in my acount, I wasn't getting any internet as well... so I check the signal icon on the top right corner and I clicked it to show the menu but all there was written was "no airport card installed"... so i though maybe it was a driver problem and since I don't know how to install drivers in Leopard, I booted back in vista and ran the BootCamp driver installation setup all over again to install the drivers again and I restarted my computer but it didn't work... would it mean the Airport card broke or fried or something? It does connect on the internet when I plug my ethernet cable.

It would help if you told us which model Mac you have.

white macbook 2.2ghz 1GB memory, 120GB hard drive running Leopard and vista in bootcamp

If it's not working in either OS X or Windows and it's fresh out of the box, then it looks as though you may have a hardware problem. I would suggest taking it back and getting it replaced with a new machine, don't settle for anything less. You should get what you paid for.

well by "new mac" i meant less than a week old (yes, just the day BEFORE Apple updates its Macbooks)... I browsed the internet wirelessly without a problem earlier today... I can't see why it would stop working just in a matter of 2 hours

well i called Apple instead, they told me to unplug everything, remove the battery and to press the power button for 5 seconds and to reboot again, fortunatly these simples steps fixed up everything. the cause : i didn't update Leopard when I got it last week.
