Wi-Fi says “No Internet Connection” on Mac

macOS shows “No Internet Connection” under a Wi-Fi network when the Mac joined the network but cannot reach the internet through it.

Applies to: macOS 13 Ventura and later. The text was checked in WiFiSettingsKit on macOS 27.2.Checked: 29 October 2026

Symptoms

A Wi-Fi login page. Hotel, café and airport networks hold traffic until you sign in. See Wi-Fi login page does not appear on a Mac.
The router has no internet. The router's link to the provider is down.
No valid address. The Mac did not get an address from the router. See Mac has a self-assigned IP address.
A DNS or filter problem. Apple does not document the test that macOS uses for this label. DNS and filters can affect it.

Open any website. A login page shows that the network needs you to sign in.
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
```
Look up a name. If ping works but this fails, DNS is the problem.
```
dscacheutil -q host -a name apple.com
```

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

Does the label mean that my Wi-Fi is broken?

No. The Wi-Fi link works. The internet behind the router, a login page or the address is the problem.
