My Ubiquiti APs are set to 100Mbps Download, 30Mbps Download. Plugged into a desktop computer, they delivered 50 to 70 Mbps downloads and 20 to 25 uploads, which is reasonable given the distance to the hotspot. Windows drivers are loaded into the USB adapter which is a PLUS. Time will tell if this will be compatible with future versions of Windows 10 (which I'm using). Would buy again if needed as they are meant to act as a backup for wired connections.
