Alfa Network AWUS1900 USB 3.0-to-802.11a/b/g/n/ac using RealTek RTL8814AU chip (PCI-ID=8813).
I didn't manage to get it working. It simply does not get recognized under wireless devices in the GUI.
PS: on linux you need to install the RTL8814AU firmware related package and then it works flawlessly but I did not manage to do the same neither on opnSense nor on freeBSD.
Someone found a solution?
i have the same Issue
