Compact USB Wi-Fi Adapter

The YOUHUA adds dual-band wireless networking to any desktop or laptop with a free USB port. It uses the RTL8811 chip to handle both 2.4 GHz and 5 GHz signals, delivering up to 600 Mbps throughput. The thumb-sized housing makes it practical for travel or permanent installation.

Check USB Port and OS

Verify that your computer has an available USB-A socket and runs Windows XP, 7, 8, 8.1, Linux or OS X, as listed in the compatibility data. No internal slot or antenna connection is required, but the host must supply standard USB power. Ensure your router broadcasts on either 2.4 GHz or 5 GHz bands.

Plug-In Wireless Upgrade

The adapter draws power directly from the USB port, so no external supply or cable is needed. It frees a system from wired Ethernet or a missing internal Wi-Fi card, providing immediate network access. The small form factor leaves adjacent ports unobstructed on most laptops and desktops.

Questions about this item

What comes in the box with the YOUHUA and do I need to buy a cable or driver disc separately?

The adapter is a USB dongle that plugs directly into a computer; no separate cable is required and drivers are installed from the operating system or the manufacturer's website.

Should I choose the 2.4 GHz band or the 5 GHz band for the 600 Mbps link speed on this RTL8811-based adapter?

The adapter supports both 2.4 GHz and 5 GHz simultaneously; the 600 Mbps rate is the combined 11ac dual-band maximum, so use 5 GHz for higher throughput and less interference when the router allows it.

What does the 600 Mbps figure mean when the adapter is connected to a real Windows 8.1 or Linux machine?

600 Mbps is the theoretical PHY-rate ceiling under ideal conditions; actual throughput will be lower due to overhead, distance, obstacles and the router's capabilities.
