Manufacturer description
The TP-Link Archer T3U Plus is a USB 3.0 WiFi adapter built for desktop PCs that either never had wireless or are stuck on an aging internal card. It runs AC1300 dual-band, so you can pull up to 867 Mbps on the 5 GHz band for gaming, HD streaming and large file transfers, or drop to the 2.4 GHz band for up to 400 Mbps on browsing, email and social media where range matters more than throughput. What separates this TP-Link adapter from flat USB dongles is the 5 dBi high-gain external antenna. It rotates and tilts, so you can aim it at your router instead of hoping a stub antenna finds a…

Frequently Asked Questions
Will this WiFi adapter work on Windows XP?
Yes. TP-Link lists driver support for Windows 11, 10, 8.1, 8, 7 and XP, which is why the Archer T3U Plus is a common pick for legacy desktop builds.
Does it work on a Mac?
It supports macOS 10.9 through 10.15 (Catalina). Newer macOS versions are not listed; check the product listing for current driver availability before buying.
How fast is the Archer T3U Plus?
AC1300 dual-band: up to 867 Mbps on the 5 GHz band and up to 400 Mbps on the 2.4 GHz band. Real-world speed depends on your router, distance and USB port.
Do I need a USB 3.0 port?
Use one if you have it. The adapter is USB 3.0, and a USB 2.0 port caps throughput well below the 867 Mbps the 5 GHz band can deliver.
Is the antenna removable or adjustable?
It is a 5 dBi multi-directional antenna you can rotate to face your router, which improves reception. Check the product listing for detachability details.
