I just upgraded to Mavericks. Now it is saying that I don't have wifi hardware installed. I did not have this problem prior to the update. Any ideas?
MacBook Pro
System Preferences > Network
Turn WiFi on.
I tried but it will not allow me to turn it on. Everything is grayed out as if wifi is no longer an option. I have tried to run a diagnostic and it is not picking up any wifi signal. The only options I have that are clickable are the Ethernet or other.
Reset the SMC.

What does reset the SMC mean?

I have a 2010 MacBook Pro running OS 10.9.2 and had the same problem: the wifi icon displayed an X and the message wifi no hardware installed.
I fixed this by going to Energy Saver in System Preferences, choosing the Power Adapter tab and de-selecting the Wake for network access option. I re-started my mac and the problem was solved. I forgot where I saw this fix but it was simply.
This also cleared up another problem with my mac not recognizing the Airport Express on my wireless network.
