Thank you for reaching the Intel(R) Communities. I understand you would like to have a WiFi adapter that can handle 5GHz frequency, and I would be more than glad to assist you with this matter to find out why the system is not recognizing the adapter Intel® Centrino® Advanced-N 6205, Dual Band.
After checking the specs of the 2 adapters, I found out that one of them supports PCIe Half Mini Card/ M.2, which is the one from the Intel® NUC Kit DN2820FYKH, and the other adapter, Intel® Centrino® Advanced-N 6205, Dual Band has no M.2 support.
For that reason, the system is not recognizing the WiFi adapter.
Sorry for being the guy with bad news.
However, the adapter in the Intel® NUC Kit DN2820FYKH is newer than Intel® Centrino® Advanced-N 6205, so performance wise, it may not be so different.
Here you can find a comparison of the 2 adapters: http://intel.ly/2yBuJ0e

Thanks for your answer!
What I did is the following: I have a HP 840 G1 laptop, with a AC7260HMW on it. I removed it and then I installed on my NUC. It works!! So I put my 6205 on the HP laptop and we're all happy now! I think that the stock wifi card on NUC and the 6205 are the same format. Windows recognizes it and installs it. Also, it allow me to modify properties on device manager but the device (6205 card) shows a yellow triangle with "code 10". No problem. The issue was fixed and now I can 'work' properly.
Thanks again for your effort and dedication with me and sorry for my english level! Have a nice day!!
