YINGHUA 600M USB WiFi Adapter 5GHz 2.4GHz 600Mbps 5dBi Antenna

Dual-Band USB Wi-Fi Adapter for PC and Mac

The YINGHUA 600M plugs into a USB 2.0 port to add wireless networking to desktops, laptops or Macs. It operates on both 2.4 GHz and 5.8 GHz bands, delivering up to 150 Mbps on the lower frequency and 433 Mbps on the higher one. The Realtek 8811 chip handles the 802.11ac standard while staying compatible with older 802.11 a/b/n/g routers. Driver installation uses a download link instead of a disc.

Gold-Plated USB Connector and 5dBi External Antenna

The adapter body measures 4.5 by 2 by 1.2 centimetres and is built from ABS plastic with a gold-plated USB head for durable contact. A 10.8 centimetre high-gain antenna screws onto the unit, providing long-range reception that can be positioned for best signal. The dual-band design lets users switch between 2.4 GHz and 5 GHz to avoid local interference. It supports Windows from Vista through 10, Linux and macOS 10.5 to 10.13.

Low-Power Operation with Passive Cooling

Drawing power directly from the USB 2.0 bus, the adapter runs without an external supply and produces no fan noise. The small form factor and ABS housing dissipate heat passively during typical browsing, streaming or file transfers. Peak throughput reaches 600 Mbps combined across both bands under ideal conditions. Actual speeds depend on router capabilities, distance and local radio environment.
