Says Wi-Fi No Hardware installed when you click on the WiFi?

So mine does give information about the WIFI and says softwareversions with a couple of details below. Still if I go to systempreferences - network it doesn't give the option to install WIFI, only bluetooth pan / firewire /ethernet 1 and 2 /vpn / ppp0E 6to4. Downloading software updates is impossible as I have no internet... what to do?

go to network prefernces

on the left side you will see + icon click on it then choose wifi and click add

if there is already a wifi in pane delete(-) it first

Dear Dblo420, Thank you for your reply. so I have tried to rewrite something in the terminal (config). I can't remember exactly what I did, but I found it on this forum as well. Then I have shut down the computer and disconnected all the cables, including the ones from the WIFI. Connected the cables again after a little while and started the computer. The "no wifi hardware installed" -notice had disappeared and I could add Wifi in my System Preferences - network again. Problem solved. Then I read your post... Thank you for responding and I am glad it has not been necessary to reinstall everything. Greetings La Cuadra

So, no Wi-Fi Hardware is Shown, correct?

If So, then you need to Reinstall the macOS:

Sometimes, changes are made to your Mac (i.e. uninstalls), and then settings (i.e. for Wi-Fi Drivers), become manipulated, technically. So, reinstalling the macOSwith place moved items back to where they should be, and will replace damaged system files.

1. First, Back up your Mac:

Create a Time Machine backup of your Mac, so that you can have something to restore your Mac from, should anything go wrong with the reinstall.

2. Then, Reinstall the macOS:

Nothing would be deleted. It's just that items that have become corrupted or deleted, would be replaced or reinstalled back to where they should be. Go Here: How to reinstall macOS from macOS Recovery - Apple Support
