A friend of mine who bought her first Mac asked me to check her Macbook Pro and fix the wifi problem. It's a second hand, previous generation 13" MBP with 2.54 GHz C2D processor. I checked Networking menu under System Preferences and couldn't find the Airport. Even when I tried to add a new connection, the drop down menu didn't give me the option for Airport. Finally, I checked "about this Mac" page. Airport was listed there but only as software. I am not a technician or an engineer but I can see that there is a hardware problem and she should take the computer to Genius Bar. Do you think this is the right thing to do or is there a quick software fix for the problem?
