When Windows 11 shows WiFi as “Connected” but there is still No Internet Access, or your browser displays “Your connection was interrupted – ERR_NETWORK_CHANGED”, it means your network settings, DNS, router, or browser connection has changed unexpectedly. This problem happens commonly on Chrome, Edge, Firefox, and Mozilla when the network driver resets, the DNS cache becomes corrupted, or your WiFi adapter temporarily loses configuration. This guide explains all the practical solutions that actually work to restore your internet connection instantly.
1. Restart the WiFi Adapter
The first fix is to refresh your WiFi network adapter so Windows creates a new connection path.
-
Open Start and search for Device Manager.
-
Expand Network adapters.
-
Right-click your Wi-Fi Adapter and choose Disable device.
-
Wait 5 seconds and right-click again to select Enable device.
-
Open your browser and check the internet again.
2. Forget and Reconnect Your WiFi
If your network profile is corrupted, forgetting the connection forces Windows to rebuild it.
-
Click the WiFi icon on the taskbar.
-
Right-click your connected network and choose Forget.
-
Select the same WiFi again and click Connect.
-
Enter the WiFi password and verify connectivity.
3. Reset DNS and Network IP
Corrupted DNS cache or IP settings often cause the ERR_NETWORK_CHANGED error. Resetting them usually fixes it instantly.
-
Press Windows + R, type cmd, and open Command Prompt (Run as Administrator).
-
Enter the following commands one by one:
ipconfig /flushdns ipconfig /release ipconfig /renew netsh winsock reset
-
Restart your PC and test your WiFi.
4. Change DNS to Google DNS
If your default DNS is slow or unstable, switching to Google DNS gives a cleaner connection.
-
Open Settings → Network & Internet → WiFi → Hardware properties.
-
Scroll down to DNS server assignment and click Edit.
-
Choose Manual, enable IPv4, and enter:
-
Preferred DNS: 8.8.8.8
-
Alternate DNS: 8.8.4.4
-
-
Click Save and test your browser.
5. Disable VPN and Proxy Settings
Active VPNs or proxies often interrupt the browser connection and trigger ERR_NETWORK_CHANGED.
-
Open Settings → Network & Internet → Proxy.
-
Turn off Use a proxy server.
-
If you're using a VPN app, open it and click Disconnect.
-
Restart your browser to confirm the fix.
6. Restart Your WiFi Router
Your router may assign wrong IP addresses or temporarily fail to provide internet access.
-
Turn off your WiFi Router.
-
Wait 10 seconds.
-
Turn it back on and let it reconnect fully.
-
Reconnect your device to the WiFi network and check internet access.

Most “Internet Connected but No Internet” and “Your connection was interrupted – ERR_NETWORK_CHANGED” problems come from temporary network conflicts, DNS issues, WiFi adapter glitches, or router misconfigurations.
