TP-Link Archer T3U Plus AC1300 Dual Band USB Wi-Fi Adapter
The TP-Link Archer T3U Plus is a dual-band USB Wi-Fi adapter for Windows and Mac computers that need faster wireless speeds. It delivers up to 867 Mbps on 5 GHz or 400 Mbps on 2.4 GHz, with high-gain antennas and MU-MIMO support to maximize coverage and reduce lag.
Why this product
Dual-band speeds up to 867 Mbps
The 5 GHz band reaches 867 Mbps for gaming and HD streaming, while the 2.4 GHz band offers 400 Mbps for general browsing and social media.
High-gain antennas with 180° rotation
Two built-in external antennas rated at 5 dBi rotate and adjust to optimize signal reception and transmission across different room layouts and obstacles.
MU-MIMO for multi-device networks
It supports two simultaneous data streams, improving throughput when used with a compatible MU-MIMO router.
USB 3.0 connection
The USB 3.2 Gen 1 interface ensures fast data transfer to and from your computer.
Windows and Mac compatible
It works with Windows 11, 10, 8.1, 8, 7, XP and macOS 10.9 to 10.15.

- Works with any Wi-Fi 5 router broadcasting on 2.4 GHz or 5 GHz bands.
- Supports Windows 11, 10, 8.1, 8, 7, XP and macOS 10.9–10.15.
- Connects via USB 3.0 (USB 3.2 Gen 1) port on desktop or laptop.
- MU-MIMO throughput gains require a MU-MIMO-capable router; standard routers will work but without those optimisations.
Best for
- Gaming and HD streaming on laptops without built-in Wi-Fi 5
- Large file downloads over 5 GHz for maximum speed
- Extending coverage to dead zones with adjustable high-gain antennas
- Multi-device networks with MU-MIMO routers
Trade-offs
- Older macOS versions: Supports macOS 10.9–10.15 only; newer versions require checking TP-Link driver support first.
- Desktops with limited USB placement: The adjustable antenna design adds 173.4 mm height, which may obstruct adjacent ports in cramped layouts.
- Networks without MU-MIMO routers: You lose the throughput advantage that dual simultaneous streams provide; standard routers still work but serve devices sequentially.
The Archer T3U Plus receives Wi-Fi signals on two separate bands for all your online needs. Choose the 2.4 GHz band for up to 400 Mbps of surfing, emailing, and social media, or switch to 5 GHz for up to 867 Mbps of gaming, HD streaming, and large file downloads.
With an advanced serial high-gain antenna structure, the Archer T3U Plus is able to maximize data transmission and reception efficiency, greatly increase reception range and provide a stable Wi-Fi connection throughout your home.
With two high-gain antennas built in one, Archer T3U Plus boosts your signal reception and data transmission much significantly than traditional single-antenna WiFi adapter. It means greater WiFi coverage and more stable WiFi connection without WiFi drops and lag, even from farther away or across multiple walls.
MU-MIMO technology provides two simultaneous data streams, improving the throughput and efficiency of the entire network when working with a compatible MU-MIMO router.
Rotate and adjust the multi-directional antenna to improve user experience and performance in different environments.
*Maximum wireless signal rates are the physical rates derived from IEEE Standard 802.11 specifications. Actual wireless data throughput and wireless coverage, and number of connected devices are not guaranteed and will vary as a result of network conditions, AP limitations, and environmental factors, including building materials, obstacles, volume and density of traffic, and AP location. Actual network speed may be limited by the rate of the product's Ethernet WAN or LAN port, the rate supported by the network cable, Internet service provider factors and other environmental conditions.
