Help to choose good wireless pcie card to create AP

[rcainc]

Hello all,
i use the last pfsense, and i want to create an access point to provides WiFi to multiple users,
can you give me advice for the best card ?
I saw that WiFi ac still not supported ?
I off course want the fastest possible card, without headache to setup …
i saw the wifi spreadsheet : https://docs.google.com/spreadsheets/d/11cF4UoNL68Me5ZC6qhjFPmzdW7mib56dBIAKz30Qpug/edit?hl=en&hl=en#gid=0
But as new pfsense admin, most of the terms are new to me, so i prefer ask you :)
Thank you.

None of them really if you're concerned about performance and reliability. Get an external AP instead such as one of the Ubiquiti models.

Ok, I will go for UAP-AC-LITE, it seem to do what i want (wpa2 enterprise with radius backend)
Thank you,
