Golden Blue USB Wi-Fi Adapter 1200Mbps AC Dual Band

This dual-band USB 3.0 wireless adapter adds 802.11ac Wi-Fi to desktop PCs and other devices lacking built-in wireless. It operates on 2.4 GHz and 5 GHz bands with a maximum link rate of 866 Mbps on 5 GHz and 300 Mbps on 2.4 GHz. The compact dongle measures 81.5 by 40.5 by 14.5 mm and draws power directly from the USB port.

Sustained load behaviour

Under continuous traffic the adapter maintains connection through automatic rate adjustment and OFDM modulation across channels 1-14 on 2.4 GHz and 36-165 on 5 GHz. Transmit power reaches 20 dBm maximum EIRP while the status LED indicates link activity. Operating temperature is rated 0 to 40 °C with humidity up to 90 % non-condensing.

Compatibility checklist

Verify the host has an available USB 3.0 Type-A port and runs 32-bit or 64-bit Windows 7, 8.1 or 10. Driver installation is required before first use. The adapter does not support Linux, macOS or Chrome OS. Ensure your router broadcasts 802.11ac or 802.11n on either band for the rated speeds.
