Cannot Rename Network Adapter Name Already Exists – How to Fix

Quick Tips

• Remove hidden or ghost network adapters through Device Manager.
• Try renaming the adapter with PowerShell if the issue persists.
• Use registry troubleshooting as a last resort, and back up the registry before making changes.

When you’re trying to rename your network adapter, you may encounter an error message like “Cannot rename network adapter; name already exists” or “Cannot rename this connection. A connection with the name you specified already exists.” As the error indicates, Windows is blocking the rename due to a duplicate name conflict.

The issue can be caused by hidden or ghost network adapters from previous configurations. On the surface, it may appear as if the old adapter no longer exists on the machine. But in the background, it can still be registered as a non-present device.

To resolve the issue, you may need to remove the hidden device causing the conflict. Start with Device Manager; if that doesn’t work, more advanced registry troubleshooting may be necessary.

Via Device Manager

First, try to remove the hidden or ghost devices via Device Manager.

Step 1. Open Device Manager.

Step 2. Under the View menu, select “Show hidden devices.”

Step 3. Expand the “Network adapters” item.

Step 4. If you see a faded/grayed-out adapter corresponding to the old or conflicting connection, right-click it and select “Uninstall device.”

Step 5. Now try to rename the adapter again using Network Connections.

Step 6. Right-click on the adapter you wish to rename and select “Rename.”

Alternatively, you can rename the adapter using PowerShell.

Step 1. Open PowerShell as an Administrator.

Step 2. In PowerShell, enter Rename-NetAdapter -Name “Oldname” -NewName “Newname”.

Replace “Oldname” and “Newname” with the actual existing adapter name and the new name you’re trying to apply to it. Make sure you enter the command correctly, including the existing adapter name and the new name you want to use.

Via the Registry

If you still receive the “Cannot rename network adapter; name already exists” error after removing hidden devices, additional network configuration information may still be present in the registry. Deleting the associated registry entries should allow you to rename your adapter as desired.

Removing Subkeys

First, try removing any lingering registry entries for the older device with the conflicting name.

Step 1. Press Windows + R to open the “Run” command.

Step 2. Type “regedit” to open the Registry Editor and click “OK.”

Step 3. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network\{4D36E972-E325-11CE-BFC1-08002BE10318}.

Step 4. If you have identified a registry entry that corresponds to the obsolete adapter, back up the registry first and delete only that specific entry.

Step 5. Restart the computer.

Step 6. Try renaming the adapter using the Network Connections panel again.

Removing the Profile

If the adapter still cannot be renamed after removing the obsolete device, check the associated network profile before making any registry changes.

Step 1. Open Registry Editor again and navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Profiles.

Step 2. Restart your machine and try renaming the adapter again using Network Connections or PowerShell.
