AC1300 dual-band USB adapter

The TP-Link Archer T4U is a USB 3.0 wireless adapter that adds IEEE 802.11ac Wi-Fi to a desktop or laptop. It targets users who need a quick upgrade from older 802.11n or built-in wireless without opening the chassis. The compact black dongle plugs into any free USB 3.0 port and supports Windows XP through Windows 8. A USB extension cable is included for flexible placement.

1300 Mbps combined throughput

The adapter delivers up to 867 Mbps on the 5 GHz band and 300 Mbps on the 2.4 GHz band using 2x2 MIMO and 256-QAM modulation. MU-MIMO support lets the device communicate efficiently with a compatible router when multiple clients are active. Real-world speed drops when distance increases, walls intervene, or the host USB bus is shared with other high-bandwidth peripherals. The 5 GHz radio tops out at 867 Mbps; the 2.4 GHz radio tops out at 300 Mbps.

USB 3.0 plug-and-play fit

A USB 3.0 header is required to reach the advertised link rates; USB 2.0 ports will limit throughput. No internal antennas or PCIe slots are needed, freeing expansion bays for other cards. The dongle measures 3.60 by 1.20 by 0.60 inches and weighs 0.35 lb, so it clears most port clusters. Operating range is 0 °C to 40 °C with 10 % to 90 % non-condensing humidity.

Questions about this item

Will the USB 3.0 interface on the Archer T4U work properly with my older USB 2.0 ports?

The adapter uses a USB 3.0 interface that is backward compatible with USB 2.0 ports, though maximum throughput will be limited to USB 2.0 speeds.

How can I confirm the dual-band radios are both active after installing the Archer T4U?

Open the network adapter settings and verify connections on both the 2.4 GHz band (up to 300 Mbps) and the 5 GHz band (up to 867 Mbps).

Does the Archer T4U package include the USB extension cable and driver media, or must I purchase them separately?

The box contains the adapter, a resource CD, a quick installation guide, and a USB extension cable; no extra items are required.
