If you are encountering the ERR_NETWORK_CHANGED error in Chromium on your macOS device, it can be quite frustrating. This error typically occurs when you have both your Wi-Fi and Ethernet connections enabled. But don't worry, we've got you covered! In this article, we will explain what causes this error and provide you with some easy-to-follow solutions.

What Causes the ERR_NETWORK_CHANGED Error?

The ERR_NETWORK_CHANGED error in Chromium is triggered when your network connection changes abruptly. This can happen when you have both Wi-Fi and Ethernet connections enabled simultaneously. Your computer gets confused about which connection to use, resulting in this error.

How to Fix the ERR_NETWORK_CHANGED Error

Here are some simple solutions to resolve the ERR_NETWORK_CHANGED error on your macOS device:

1. Disable Wi-Fi or Ethernet

The easiest way to fix this issue is to disable either your Wi-Fi or Ethernet connection, depending on which one you prefer to use. Follow these steps:

1. Click on the Wi-Fi icon in the menu bar at the top right corner of your screen.
2. Select "Turn Wi-Fi Off" to disable Wi-Fi.
3. If you prefer to use Wi-Fi, disable your Ethernet connection by unplugging the Ethernet cable from your computer.

Once you disable one of the connections, the ERR_NETWORK_CHANGED error should no longer appear.

2. Prioritize Wi-Fi or Ethernet

If disabling one of the connections is not an option for you, you can prioritize either your Wi-Fi or Ethernet connection. Follow these steps:

1. Click on the Apple menu icon in the top left corner of your screen and select "System Preferences."
2. Click on "Network."
3. In the left sidebar, you will see a list of network connections. Drag and drop either Wi-Fi or Ethernet to the top of the list, depending on your preference.
4. Click on the gear icon at the bottom left and select "Set Service Order."
5. In the pop-up window, make sure the connection you prioritized is at the top of the list. If not, click and drag it to the top.
6. Click "OK" to save the changes.

By prioritizing one connection over the other, you can avoid the ERR_NETWORK_CHANGED error.

3. Reset Network Settings

If the above solutions didn't work, you can try resetting your network settings. Follow these steps:

1. Click on the Apple menu icon in the top left corner of your screen and select "System Preferences."
2. Click on "Network."
3. In the left sidebar, select the connection you want to reset (Wi-Fi or Ethernet).
4. Click on the minus (-) button at the bottom to remove the connection.
5. Click on the plus (+) button and add the connection back.
6. Click "Apply" to save the changes.

Resetting your network settings can help resolve any configuration issues that might be causing the ERR_NETWORK_CHANGED error.
