AC1300 dual-band USB 3.0 Wi-Fi adapter

The TP-Link Archer T3U is a mini USB 3.0 wireless adapter that adds dual-band 802.11ac connectivity to a desktop or laptop. It delivers up to 867 Mbps on 5 GHz and 400 Mbps on 2.4 GHz with MU-MIMO support.

Suits portable dual-band Wi-Fi upgrades.

This adapter suits users adding dual-band AC1300 Wi-Fi to older PCs or laptops via USB 3.0. It is not for systems running Windows versions newer than Windows 10 or macOS versions newer than 10.13.

USB 3.0 interface enables AC1300 speeds

The USB 3.0 connection provides up to 10x faster transfer speeds than USB 2.0, which is required to realise the AC1300 wireless data rates. Using a USB 2.0 port will limit throughput.

Questions about this item

Does the Archer T3U box include a driver CD or do I need to download software separately?

The package contains a Resource CD plus a Quick Installation Guide; drivers are on the disc and also available from the TP-Link support site.

The adapter lists 400 Mbps on 2.4 GHz and 867 Mbps on 5 GHz — which band should I use for a desktop 10 metres from the router?

Use the 5 GHz band for higher throughput at that distance; the 867 Mbps link rate and MU-MIMO support give lower latency than the 2.4 GHz 400 Mbps band.

What real-world throughput can I expect from the AC1300 rating when the adapter is plugged into a USB 3.0 port?

USB 3.0 removes the 2.0 bottleneck so the adapter can sustain rates close to the 867 Mbps 5 GHz PHY speed, though actual throughput depends on router capability and interference.
