Macbook Pro - Suddenly no Wi-Fi hardware installed...

post #1 of 2
Thread Starter 
My daughter was using her Macbook Pro (intel based, about 1 1/2 years old). When it woke up from sleep, she could no longer connect to our wi-fi. The wi-fi is working fine and when trying to connect, it shows a message " no hardware installed".

The laptop is running fine otherwise and works with an ethernet cable for internet connection without issue.

Is there a simple way to fix this? On a PC laptop I would know what to do but on a crapbook I am clueless.

All help much appreciated as my daughter is driving me nuts.

There is no Device Manager, but OSX has a similar utility called the System Profiler.

From there, click on 'Airport Card' listed under the heading 'Network'.
