UGREEN AC650 11ac Dual-Band Wireless USB Adapter | 20204
The UGREEN CM448 (item 20204) is a small USB Wi-Fi adapter that adds dual-band 802.11ac (Wi-Fi 5) to a desktop PC or replaces a weak or faulty laptop Wi-Fi card. It reaches up to 433Mbps on 5GHz and up to 200Mbps on 2.4GHz and uses a Realtek RTL8811CU chip.

Dual band, AC650: The adapter works on both the 5GHz band (up to 433Mbps) and the 2.4GHz band (up to 200Mbps). UGREEN positions 5GHz for lag-free gaming and 4K streaming, and 2.4GHz for everyday use such as web browsing and older devices.
Driver-free on Windows 11 and 10: On Windows 11 and Windows 10 it works without installing a driver. On Windows 8.1, 8 and 7 you install the driver from the UGREEN installation guide.

Use it as a Wi-Fi hotspot: The adapter supports Station mode and Soft AP mode at the same time. In Soft AP mode a computer connected by cable can share its internet as a Wi-Fi hotspot for phones and other devices.
Compact design with LED and cap: The mini size lets you leave it plugged into a laptop. A blue LED stays on while it works and flashes during data transfer, and a dust cap protects the USB connector when it is not in use.

Good to know
Hotspot (Soft AP) mode needs hotspot software on the computer. The speeds above are the maximum link rates of each band.
