Description
Desktop WiFi upgrade over USB 3.0
The UGREEN CM493 brings AC1300 dual-band wireless to PCs through a USB 3.0 connection, pairing high-gain antennas with optional hotspot sharing for flexible home or office networking.
Throughput by band
| AC1300 class total | Up to 1300Mbps (UGREEN laboratory figures; actual rates depend on surroundings) |
| 5 GHz link | Up to 867Mbps |
| 2.4 GHz link | Up to 400Mbps |
Plug into a native USB 3.0 port to reach rated speeds. Keep other 2.4GHz or 5GHz radios on the same channels apart where possible to limit mutual interference.
Antenna reach
Two rotatable 5dBi high-gain antennas aim for open-area coverage around 50 metres without walls, with stable signal after passing through two typical walls.
Client and hotspot together
Station Mode and Soft AP can operate concurrently—your wired machine joins an existing router while also broadcasting a hotspot other gadgets may join.
Windows support and drivers
Supported on Windows 11, 10, 8.1, 8, and 7; MacBook is not supported. Windows 11 and 10 install without a separate driver after insertion. Older Windows builds without a CD drive can use the PDF installation manual from product documentation. For reliable links, avoid USB hubs or extension cables between the PC and adapter.
