Review on 📶 FebSmart PCIE Wi-Fi Card for Windows Server and Windows 7 8 8.1 10 (32/64bit) System - High Power Wireless N600 Adapter, 2.4GHz 300Mbps or 5GHz 300Mbps - FS-N600HP by Reginald Hamilton

Very easy installation and doesn't require external USB power like many other wifi cards I've seen in my search. Low profile bracket included and easy to install. I installed this in an old Dell Optiplex 7010 and it works great. I live in the middle of nowhere with mediocre internet coverage at best, so I can't comment on the speeds it can reach. I didn't have to fiddle with the driver disk that came with it, it worked for me right out of the box.
