## Troubleshooting

* Install the latest Windows updates
* Launch the Hedge app with administrator rights ("Run as administrator")
* Run the following command in PowerShell to list all the network adapters recognized by Windows. Look for the actual physical network adapters that show a MacAddress, and are not recognized as physical.

{% code overflow="wrap" %}

```
Get-WmiObject -Class "Win32_NetworkAdapter" | Format-List -Property Name,PhysicalAdapter,MacAddress
```

{% endcode %}

* Install vendor-specific drivers for physical network adapters that are not recognized as physical.
* Attempt to rebuild the Windows Management Instrumentation (WMI) network adapter class.
  * Open an elevated Powershell, then navigate to this directory using cd:
  * ```
    cd C:\Windows\System32\wbem
    ```
  * Rebuild the WMI adapter class:

    ```
    mofcomp C:\Windows\System32\wbem\NetAdapterCim.mof
    ```
* Temporarily uninstall the network adapter.
  1. Connect your PC to the Internet with a wired connection.
  2. In Device Manager, right-click on the network adapter and select "Uninstall device."
  3. Try activating
  4. To reinstall that network adapter, do a "Scan for hardware changes" in Device Manager.
