Hi up64aj3386,
We understand your MacBook Air is unable to connect to Wi-Fi and you are unable to perform diagnostics.
The screen you've shared indicates your MacBook Air was unable to connect to the internet to complete diagnostics. This would make sense, since you are unable to connect to Wi-Fi.
You may want to follow the steps found within the following resource, to help ensure your Wi-Fi network is configured correctly.
Manage the Wi-Fi connection on your Mac
If your issue persists once the network is correctly configured, you'll want to follow these steps.
If your Mac doesn't connect to the Internet over Wi-Fi
Take care.
