5. Click “OK” to save the changes and exit the adapter properties window.

Step 2: Verify Workgroup or Domain Settings

The next step is to ensure that your Windows 11 device is properly configured to participate in the correct workgroup or domain. This is crucial for network discovery to function correctly, as devices need to be able to identify and communicate with each other.

1. Open the “System” settings by searching for it in the Start menu or pressing the Windows key + I.
2. In the System settings, navigate to the “About” section and locate the “Workgroup” or “Domain” information.
3. Verify that the workgroup or domain name matches the one used by the other devices on your network.
4. If the workgroup or domain information is incorrect, you can update it by clicking on the “Change settings” link and entering the correct information.

Step 3: Enable Network Discovery and Sharing

Windows 11 has a built-in feature called “Network Discovery” that controls the visibility and sharing of resources on the network. Ensure that this feature is enabled on your device.

1. Open the “Control Panel” and navigate to the “Network and Sharing Center”.
2. Click on “Change advanced sharing settings” in the left-hand menu.
3. In the “Network Discovery” section, ensure that the “Turn on network discovery” option is enabled.
4. Also, make sure the “Turn on file and printer sharing” option is enabled.
5. Click “Save changes” to apply the settings.

Step 4: Check Firewall Settings

The Windows Defender Firewall can sometimes interfere with network discovery if it’s not properly configured. I’ll guide you through the steps to verify and adjust the firewall settings.

1. Open the “Control Panel” and navigate to the “Windows Defender Firewall with Advanced Security”.
2. In the left-hand menu, click on “Inbound Rules” and “Outbound Rules”.
