Error messageGoogle associates ERR_NETWORK_CHANGED with disconnecting or joining another network during page loading. It is distinct from a site refusing a connection, a timeout or a DNS failure, and does not prove a router fault.

Step-by-step solutions

Let the connection settle, then reload once

Estimated time: 2 min
Easy
Low risk

Avoid repeating sensitive submissions.

If switching Wi-Fi or connections, wait until the network is connected and reload a public page once.
For a payment or form, first check whether it completed. If the page now works, that isolated event does not call for a network reset.

Watch which connection changes

Estimated time: 4 min
Easy
Low risk

Keep one stable connection during the test.

Check whether the computer moves between Wi-Fi networks or between Wi-Fi and Ethernet. Retry without switching connections while the page loads.
If changes recur without your intervention, note when they happen and whether other apps disconnect too. Continue with intermittent-internet troubleshooting.

Still not working?

Give support the message and observed connection changes. If the device stays offline, follow ERR_INTERNET_DISCONNECTED; if it remains connected, do not automatically diagnose loss of internet access.
