Dual-Band USB 3.0 Wi-Fi Adapter

This USB 3.0 wireless adapter uses the RTL8812BU chipset to add dual-band Wi-Fi to desktops and laptops. It supports IEEE 802.11ac and legacy standards at up to 1300Mbps. The dual 2dBi antennas rotate 180 degrees for flexible positioning. It works with Windows 7 through 10 and Mac OS 10.9 to 10.15.

Replacing Internal Cards or Missing Wi-Fi

It replaces a faulty internal laptop Wi-Fi module when repair cost is high. It upgrades older built-in wireless hardware to a faster AC1200 experience. It adds Wi-Fi to a desktop without running Ethernet cables. The USB 3.0 interface provides efficient transmission for the 256QAM signal.

2.4 GHz Range and 5.8 GHz Throughput

The 2.4 GHz band offers longer connection distance and stable coverage for general use. The 5.8 GHz band handles HD video streaming smoothly with less interference. Maximum RF power reaches 18dBm. Soft AP mode shares a wired connection wirelessly. Win10 does not support the Wi-Fi transmitter function.

Questions about this item

What USB port does the YINGHUA RTL8812BU adapter require?

It needs a USB 3.0 port for efficient transmission and will also work in USB 2.0 sockets at reduced speed.

Which driver step is often missed when installing this AC1200 dongle on Windows 10?

After plugging it in, run the supplied driver installer before Windows attempts its generic driver; otherwise the 5.8 GHz band may not appear.

When should the dual 2 dBi antennas be replaced on this USB Wi-Fi adapter?

Replace them if the hinges loosen so they no longer hold position after 180 degree rotation or if signal drops noticeably on both 2.4 GHz and 5.8 GHz bands.
