Wifi problem in MacBook Air

[WhiteCoder]

Hi guys. I just formatted my Macbook Air today and I can't access wireless. The option is not in the top right and also I can't add it on Network Preferences. I can only access internet with cable and the wifi option can't be selected. Can you please tell me how to configure wireless or make it work again?

It doesn't show in Network under system preferences? Thats an odd one if not. Never had that problem with my air.

Do you know where to check if my internet card is broken or not working?
