Connected to network but no internet access

When your Mac says it is connected to Wi-Fi, it means you have linked to your local router, but the router itself cannot reach the broader internet. 

Quick Fixes to Try

• Restart your router and modem: Unplug your router and modem from power, wait 10 to 30 seconds, and plug them back in. 

• Restart your Mac: Go to the Apple menu () > Restart to clear out temporary network glitches. 

• Forget and reconnect to the network:

1. Open System Settings > Wi-Fi.
2. Click Details (or the info/three-dots button) next to your network.
3. Select Forget This Network and confirm.
4. Reconnect by selecting your network and re-entering the Wi-Fi password. 

• Turn off your VPN or security software: If you use a VPN or third-party firewall, temporarily disable it to see if it is blocking your traffic.

• Check your date and time: Go to System Settings > General > Date & Time and make sure Set date and time automatically is turned on (incorrect time can break secure web connections).

• Change your DNS servers:

1. Go to System Settings > Wi-Fi > Details next to your network, then click DNS.
2. Click the + button and add public DNS servers like 8.8.8.8 and 8.8.4.4 (Google DNS), then click OK

• Create new Network Location

1. Open System Settings
2. Click on Network
3. Click the ••• / down caret at the bottom of the preference pane
4. Select Locations > Edit locations.
5. Click the (+) button, give the location a name (you can delete it or rename it later), and see if that corrects the issue.
