If the wireless adapter works in Linux* the issue is software related somehow.
I have the Intel® NUC D54250WYK and Intel® Dual Band Wireless-AC 7260 working here, which leads me to the following questions:
- What version of Windows* 7 are you using?
- Is it a clean/fresh installation?
- Did you install the Intel® Chipset Device Software and Intel® Management Engine first?
- Did you try a different driver version? Intel® PROSet/Wireless Software — Intel® PROSet/Wireless Software downloads
First, I wasn't referring to the card working in Linux, rather Linux vs Windows installations. Hard to believe that a free OS built and maintained by volunteers is easier and more trouble free installing than the updates and driver hell that windows is. That said, it isn't working in Linux either. I'm returning it and going to another non-Intel card.
As to your question: 1) Fresh install of Win 7 64bit professional, followed by 2) SP1 update, 3) Intel chipset device software and 4 Intel management engine. I'm done with Windows and this card, and don't want to spend my time installing drivers fruitlessly. Remarkable as Intel engineered both the computer and the wifi card that they don't work for me and many many other users.
If it did not work in Linux* there is a chance it was a hardware issue.
