Are we talking about windows 10? If so, your adapter has been discontinued.
And, if we are talking about a laptop, you cannot just simply get another adapter:
You will need to consult with the laptop manufacturer.
I'm running Windows 7 on an Asus laptop. After encountering my issues, I realized that the adapter is no longer supported, which is why I'm so annoyed with Intel from prompting me to uninstall it.
Thanks for pointing out the issue of obstacles to installing a new adapter. I hadn't stumbled over that yet. Ugh. Appreciate the reply --
