600Mbps Wireless WiFi Adapter + USB Bluetooth Transmitter Receiver 2In1 Wi-Fi Dongle Adapter Lan USB Ethernet Driver-free Network Card For PC Laptop

Ok

Produced based on the RTL8821CU chip (single-chip controller), which provides WiFi 802.11AC/ABGN USB WLAN and BLUETOOTH 4.2. Even if you see the 5GHz band in the picture, it is not indicated in the description, i.e. the device does not see this band. The connection speed is much lower than with a mobile phone at the same distance from the router (about 8 meters): (2-4 Mbps vs 20 Mbps on mobile).

Works well. Many thanks.
