Chromium describes this error as: “The Internet connection has been lost.” Chrome found no working connection on the Mac.

Applies to: Google Chrome and other Chromium browsers on all current macOS versions.Checked: 29 October 2026

Symptoms

Wi-Fi is off or not joined. The Mac is not on any network.
No valid IP address. The Mac did not get an address from the router. See Mac has a self-assigned IP address.
A VPN that blocks traffic. Some VPNs block all traffic while they connect.
The router or provider is down. If other devices also fail, the problem is not the Mac.

Click the Wi-Fi icon in the menu bar. Make sure that Wi-Fi is on and that the Mac joined your network.
Show the address and router of the Wi-Fi service.
```
networksetup -getinfo Wi-Fi
```
Find the router address in the gateway line. Then ping it.
```
route -n get default
ping -c 5 192.168.1.1
```
Ping an address on the internet. This test does not use DNS.
```
ping -c 5 1.1.1.1
```

Turn Wi-Fi off and on, or join your network again.
If the address starts with 169.254, renew the DHCP lease. See Renew the DHCP lease on a Mac.
Disconnect the VPN for a test.
Restart the router if other devices also fail.

Check Wi-Fi, the router, the internet, DNS and a login page in one command.

Why does Chrome say No internet while Wi-Fi is connected?

The link to the router works, but the Mac has no path to the internet. See Mac connected to Wi-Fi but no internet.
