We understand that the built-in wireless network card of your computer is not working. It is possible that the new wireless network card that you've installed on the computer is having a conflict with the other components. This is the reason why we're recommending you to use the built-in wireless network card. This is for us to verify is you'll be able to install the version 1709 update. If the built-in wireless network card is not working, you can temporarily connect to the Internet using a wired connection so that the computer can download the update.
Kindly let us know if you're able to install the update while the third party wireless network card is removed and while connected to the Internet using a wired connection.
