Find the likely cause

• If the Mac will not join any network, switch Wi-Fi off and on (step 1), then restart the Mac (step 2).
• If the Mac joins the network but no page loads, check the date and time (step 3) and switch off any VPN for a test (step 4).
• If the trouble started after you set up a VPN, disconnect it for a test (step 4).
• If the Mac gets online through a phone hotspot but not on your own Wi-Fi, the network is the likely problem, so follow "If this does not work".
• If other devices on the same Wi-Fi fail as well, restart the router, as "If this does not work" describes.

Step by step

1. Turn Wi-Fi off and on

   Click the Wi-Fi icon in the menu bar, or Control Centre, and switch Wi-Fi off. Wait ten seconds and switch it on.

   Done

2. 

   Restart the Mac

   Click the Apple menu and choose Restart.

   Done

3. Restart the router

   Unplug it for 30 seconds and give it a few minutes to come back.

   Done

4. Forget the network and join again

   Open System Settings, Wi-Fi. Click Details next to the network, or the three dots, and choose Forget This Network. Select it again and enter the password.

   Done

5. 

   Check the date and time

   Open System Settings, General, Date & Time and switch on Set time and date automatically. A wrong clock breaks secure websites.

   Done

6. Turn off VPN and security software for a test

   Disconnect any VPN under System Settings, VPN, and pause firewall or antivirus apps briefly to see whether they are blocking the connection.

   Done

7. Run Wireless Diagnostics

   Hold the Option key and click the Wi-Fi icon in the menu bar. Choose Open Wireless Diagnostics and follow the steps. It tests the connection and suggests fixes.

   Done

8. 

   Update macOS

   Use a phone hotspot or a network cable to get online, then open System Settings, General, Software Update.

   Done

About this guide

Check first whether other devices work on the same Wi-Fi. If they do, the Mac needs attention. If nothing connects, restart the router or contact your provider.

Good to know

A login page for hotel or café Wi-Fi sometimes fails to appear. Open Safari and go to captive.apple.com to trigger it.

If the Mac sees no networks at all and the Wi-Fi menu says "No hardware installed", that is a hardware fault. Contact Apple.

Wi-Fi that is fine near the router and poor elsewhere is a signal problem, not a Mac problem.

In short: Wi-Fi off and on, restart, date and time, VPN off, update macOS, Wireless Diagnostics.
