Hello jantorefromgodvik,
Welcome to the Apple Support Communities!
I understand that you are seeing a “No hardware installed” alert when turning on Wi-Fi on your Mac. In this situation, there are a couple of different steps I would recommend to start the troubleshooting process. Please work through the steps in the following two articles to reset both your computer’s SMC and PRAM and let me know if the issue continues.
Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support
OS X Mountain Lion: Reset your computer’s PRAM
Have a great day,
Joe
