THE PRACTICAL PERSPECTIVE
Overall review.
Check driver support before buying
TP-Link publishes drivers by hardware revision. Check the download page for your operating system and save the installer in advance if this computer already has trouble getting online.
Allow room around the port
The hinged antenna projects from the USB socket. At a desk, leave enough clearance to adjust it, especially if the computer sits against a wall or other cables use adjacent ports.
Choose a band for the room
Try 5GHz when the router is close. Test 2.4GHz if walls weaken the signal. The advertised numbers are maximum Wi-Fi link rates. Internet throughput depends on the router, interference and your connection.
