Plug the key into a USB port, then install the TP-Link driver if Windows does not recognise it on its own. Then pick your network and type the password.

5 GHz is faster when the router is close. 2.4 GHz reaches further and goes through walls better, useful if the router is at the other end of the house.

TP-Link WiFi Key

Q: What is a Wi-Fi key for?

It adds Wi-Fi to a desktop PC that has none, or replaces the weak Wi-Fi of an old laptop. It simply plugs into a USB port.

Q: What does AC1300 mean?

It is the theoretical maximum speed, both bands combined, on Wi-Fi 5. Real speed depends on the router, the distance and the walls in between.

Q: Unstable connection, what can I do?

Bring the key closer to the router with a USB extension, up high and in line of sight. Also update the driver and try the other band.

Which Wi-Fi key for a desktop PC?

Many desktop PCs have no Wi-Fi, and old laptops pick up a poor signal. A USB key solves it without opening the computer.

The TP-Link Archer T3U Plus AC1300 is dual-band: 5 GHz for speed when the router is close, 2.4 GHz to get through walls. Its high-gain antenna reaches further than a small key with no antenna.

If the PC sits under the desk behind its metal case, the signal arrives weakened. A USB extension lets you put the key up high, in sight of the router, for a much steadier connection.
