USB 3.0 Dual Band WiFi Adapter

The YINGHUA USB 3.0 Dual Band WiFi Adapter adds 2.4 GHz and 5.0 GHz wireless connectivity to desktops and laptops via a USB 3.0 port. It uses the RTL8812BU chipset and supports the 802.11 ac/a/b/g/n standards with a maximum combined transfer rate of 1167Mbps. The adapter includes a built-in antenna and offers WEP, WPA, WPA2 and WPS encryption options. It is compatible with Windows XP through Windows 8 and Mac operating systems.

Upgrade from USB 2.0 or single band adapters

This adapter replaces older USB 2.0 or single band wireless dongles by providing USB 3.0 throughput up to 10 times faster than USB 2.0. The jump is worthwhile when your router supports 5.0 GHz 802.11ac and you need the 867Mbps link speed on that band for reduced congestion. It also adds dual band flexibility for environments where the 2.4 GHz band is crowded. The USB 3.0 interface remains compatible with USB 2.0 and USB 1.1 ports at reduced speeds.

Check OS support and router band availability

Before ordering, verify that your operating system is listed among the supported versions: Windows XP 32/64, Vista 32/64, Win 7 32/64, Win 8 32/64 or Mac. Confirm your wireless router broadcasts a 5.0 GHz 802.11ac signal to use the higher 867Mbps rate; otherwise the adapter will operate on 2.4 GHz at 300Mbps. Ensure a free USB port is available, preferably USB 3.0 for full throughput. No external antenna connection is required as the antenna is built in.

Questions about this item

What USB port does the adapter need to reach its top speed?

A USB 3.0 port is required for the 10 times faster transmission rate; it also works with USB 2.0 and 1.1 ports at lower speeds.

Which driver step is often missed during setup?

Installing the driver for the RTL8812BU chipset before plugging the adapter in, otherwise Windows may load a generic driver that limits performance.

When should the built-in antenna be checked or replaced?

The internal antenna is not user-replaceable; if signal drops persist after driver updates and router checks, the whole adapter would need replacing.
