SKU CH-B49T-YASNF

Adds dual-band Wi-Fi up to 1300 Mbps and Bluetooth connectivity to a PC or laptop via USB

  • Dual-band Wi-Fi up to 1300Mbps for fast connections
  • RTL8822BU chipset drives 2.4GHz and 5GHz bands
  • Works with Windows 2000 through Windows 10 and Mac OS
  • Compact USB adapter adds wireless to any desktop or laptop
  • Operates from -20°C to 45°C in up to 90% humidity

Dual-band USB Wi-Fi adapter

This YINGHUA dongle adds wireless networking on 2.4 GHz and 5 GHz bands plus Bluetooth support to desktops and laptops. It connects via a standard USB port and uses the RTL8822BU chipset. The adapter reaches a maximum Wi-Fi speed of 1300 Mbps and a Bluetooth transmission distance of 10 meters. Operating temperature ranges from -20°C to 45°C.

Suits PCs needing wireless

Ideal for Windows 7, 8 and 10 systems that lack built-in Wi-Fi or Bluetooth, or where the internal module has failed. It also works with Windows 2000, XP, Vista and Mac OS for Wi-Fi only. Buyers who need Bluetooth on Windows XP, Vista or Mac OS should look elsewhere because the Bluetooth driver does not support those systems. Anyone requiring an internal PCIe card rather than a USB device will need a different form factor.

1300 Mbps dual-band Wi-Fi with 2 dBi antenna gain

The single specification that decides fit is the 1300 Mbps maximum wireless rate across IEEE 802.11 n, g, b and ac standards on both 2.4 GHz and 5 GHz frequencies. Antenna gain is 2 dBi and maximum RF power is 18 dBm. If your network demands higher throughput or different antenna characteristics, this adapter will not meet that requirement.

Questions about this item

How do I install the YINGHUA wireless adapter, and what driver step is often missed?

Insert the adapter into a USB port, then install the RTL8822BU chipset driver for Wi-Fi; the separate Bluetooth-compatible driver must also be installed, as it is not included with the Wi-Fi driver and is required for Bluetooth function.

What maintenance or replacement will the adapter need over time?

The adapter has no user-serviceable parts; keep the USB connector and antenna area free of dust, and ensure the operating temperature stays within -20°C to 45°C to avoid premature failure.

What performance limit appears first during sustained high-speed transfers?

The 2 dBi antenna gain and 18 dBm maximum RF power cap range and throughput, so sustained 1300 Mbps speeds are limited by signal quality and thermal throttling within the -20°C to 45°C operating window.
