Now that the operating system has been upgraded, would like to make sure if the drivers are installed on the computer.

  1. Press the “Windows + R” to launch the run window.
  2. Type “devmgmt.msc” in the run window and press the Enter key.
  3. Locate Network Adapters in the Device Manager window and check the devices listed.
  4. Right click the device and click “Enable”. 

If network adapter is not an available option, look for the option “other devices”.

As a workaround in the meanwhile, please run the Error Helper fix tool from the link below.


  1. Click the above mentioned link.
  2. Save the file to the desktop.
  3. Double-Click the downloaded file and click “Run”.
  4. Follow the onscreen instructions to complete the installation.
  5. Open the tool, and scan for errors.
  6. Click repair when prompted to repair the errors.

This should fix the issue. Please reply if you need further assistance.

Thanks & Regards
