- Restart the Mac: On our MacBook Neo, Restart… sits between Sleep and Shut Down… in the Apple menu.
- Check the date and time: On our MacBook Neo it is on, with Source: Apple (time.apple.com.).
- Turn off VPN for a test: On our MacBook Neo, VPN is its own sidebar row directly under Network.
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.
