macbook air wifi:no hardware installed

I have a macbook air that does not have wifi.


The wifi symbol at the top of the screen has a cross thru it and states "wifi: no hardware installed"


I have updated via bluetooth.


The macbook has not been dropped, or damaged in anyway.


Please tell me how we fix the problem

The error message displayed "WiFi: No hardware installed" means that either WiFi adapter is not installed in your Mac or it has failed. In your case it is installed but has failed.

Here is a link that will go through steps necessary to determine the status of the WiFi adapter. Part of the instructions are the same as what Dominic23 recommended above however there is more by using the Terminal App. https://macreports.com/macos-wifi-no-hardware-installed-error-fix/
