What this adapter does

The Teamyo USB 3.0 Wi-Fi adapter adds dual-band wireless connectivity to desktops or laptops. It supports 802.11ac with maximum link rates of 867 Mbps on 5.8 GHz and 400 Mbps on 2.4 GHz. Windows 10 and 11 users can plug it in without installing drivers.

Practical limits of the USB 3.0 interface

The USB 3.0 connection provides up to ten times the throughput of USB 2.0, removing the bus bottleneck for high-rate Wi-Fi. Actual throughput still depends on router capabilities, channel width, interference and client support for MU-MIMO streams.

Installation experience

Rotate the dual 5 dBi antennas up to 180 degrees to optimise signal direction. Windows 7, 8, XP, macOS and Linux require the driver from the included mini CD or a download. The soft-AP hotspot feature works only when the host PC has a wired internet connection.

Questions about this item

Should I pick the 2.4 GHz or 5.8 GHz band for my setup?

The adapter supports both bands simultaneously; 2.4 GHz reaches up to 400 Mbps and penetrates walls better, while 5.8 GHz reaches up to 867 Mbps with less interference.

What does the 1300 Mbps rating mean once the adapter is plugged into my PC?

It is the combined theoretical maximum of both bands — 867 Mbps on 5.8 GHz plus 400 Mbps on 2.4 GHz — actual throughput will be lower due to overhead and signal conditions.

How does the USB 3.0 interface affect real-world speed compared with USB 2.0?

USB 3.0 provides up to 10 times the bus bandwidth of USB 2.0, so the 802.11ac radio can deliver its full 867 Mbps on 5.8 GHz without being bottlenecked by the port.
