AC1300 dual-band USB Wi-Fi adapter

The TP-Link Archer T3U adds 2.4 GHz and 5 GHz wireless connectivity to a desktop or laptop via a USB 3.0 port. It delivers up to 400 Mbps on the 2.4 GHz band and 867 Mbps on the 5 GHz band. MU-MIMO and beamforming support help maintain a stable link when multiple devices are active. The compact black dongle weighs only 0.02 pounds.

Suits Windows and macOS users needing a portable

This adapter works with Windows 11, 10, 8.1, 8, 7 and XP as well as macOS 10.9 through 10.14. It is a good fit for travelers or anyone who wants a plug-in solution without opening a case. Buyers who require Wi-Fi 6E or Wi-Fi 7 capability should look at a different class of adapter. Systems without a USB 3.0 port will not benefit from the faster interface.

Simple driver installation on supported operating

Insert the dongle, install the driver from the supplied media or the vendor website, then select your network. The miniature design leaves adjacent USB ports accessible. The main issue reported is occasional driver conflicts after major OS updates, which a reinstall usually resolves. No internal hardware work is required.

Questions about this item

Does my computer need a USB 3.0 port to get the 867 Mbps 5 GHz link speed?

Yes, the adapter uses a USB 3.0 interface which provides up to 10x faster transfer speed than USB 2.0, so a USB 3.0 port is required to reach the 867 Mbps 5 GHz rate.

Will the Archer T3U work with my Windows 7 desktop and still support MU-MIMO beamforming?

The adapter supports Windows 7 and includes MU-MIMO technology for beamforming connections, so it will function with that OS and deliver the beamforming benefit.

How can I confirm the adapter is connected at the 5 GHz 867 Mbps rate after installation?

Open the network status or TP-Link utility on your PC; it will show the active band and link speed, confirming a 5 GHz connection at 867 Mbps when conditions allow.
