Nano USB Wi-Fi adapter

The TP-Link Archer T2U Nano is a compact USB 2.0 wireless adapter that adds dual-band Wi-Fi to a desktop or laptop. It supports IEEE 802.11ac and older standards, delivering up to 600 Mbps combined throughput with 200 Mbps on the 2.4 GHz band and 433 Mbps on the 5 GHz band. The nano form factor measures just 0.73" x 0.59" x 0.28" and stays almost flush with the port.

Who this suits

This adapter suits users who need to add or upgrade Wi-Fi on a Windows system from XP through Windows 10 or on Mac OS X 10.9 to 10.13 without opening the case. It works with any router using WEP, WPA-PSK, WPA2-PSK or 802.1x security and its omnidirectional antenna handles typical home or office ranges. Builders who require an internal PCIe card, external antennas or USB 3.0 bandwidth should look at other form factors.

Deciding specification

The USB 2.0 interface caps real-world throughput well below the nominal 600 Mbps link rate, so the adapter is best chosen for convenience and 5 GHz capability rather than maximum speed. If the host system only has USB 2.0 ports, this limitation is unavoidable.

Questions about this item

Should I choose the 2.4 GHz or 5 GHz band for the 600 Mbps rating?

The 600 Mbps figure combines both bands; 2.4 GHz reaches 200 Mbps and 5 GHz reaches 433 Mbps. Pick 5 GHz for higher throughput and less interference, or 2.4 GHz for better wall penetration.

What does the AC600 label mean for actual throughput on my laptop?

AC600 is the combined PHY rate. Real-world speeds are lower due to overhead, signal quality and the USB 2.0 link, typically delivering well under the 433 Mbps 5 GHz maximum.

How does the USB 2.0 interface affect the 433 Mbps 5 GHz speed?

USB 2.0 limits the data path, so sustained throughput will fall below the 5 GHz PHY rate. The adapter still provides dual-band connectivity and the security features listed.
