I've got a big problem with my airport card.
I've got a Mac Book Pro 17" 2.5 GHz Intel Core 2 Duo (Model Number: A1261) of 2008. My airport card worked very well till one day that I lost my connection unexpectedly. The only one message is: "Airport: Off" and "Turn Airport On" but although I try to turn it on the airport stays off. I've changed the card, thinking that was the problem, but isn't it. Now my Airpor work well at Mac startup and after a random time she goes off. When she's off the only way I can rekindle it is to restart the Mac.
I thought it can be a software problem and I've format my Mac several times with no results. The problem still the same.
Searching through internet I've found that there is a little card under the Airport card that can be the problem. With iFixit I've found the part and the guide to how to change it but before spending $100 I thought I'd ask here if it really can be the problem or not.
Do you have any ideas?
