If your MacBook is connected to WiFi but has no internet access, you can try restarting your router and adjusting the location of your Mac to improve the connection.

To restart your router, unplug it from the power source, wait for 30 seconds, and then plug it back in. This can help resolve any temporary connectivity issues.

To adjust the location of your Mac, move it closer to the wireless access point or router. Walls and other obstacles can interfere with the signal, so finding a more central location for your Mac can improve the connection.

If you’re still experiencing issues after restarting the router and adjusting the location of your Mac, you may need to troubleshoot further or contact your internet service provider for assistance.

Remember to check for any firmware updates for your router and ensure that your MacBook’s software is up to date. Additionally, running a scan with antivirus software can help identify and resolve any potential security issues that may be affecting your internet access.
