UGREEN USB WiFi 6 Adapter, AX1800 1800Mbps WiFi Dongle | 90340
The UGREEN CM499 (item 90340) is an AX1800 dual-band Wi-Fi 6 (802.11ax) USB adapter for desktop PCs and laptops. It connects over USB 3.0 and reaches up to 1201Mbps on the 5GHz band, for a combined AX1800 rating.

Wi-Fi 6 with OFDMA and 1024QAM: Wi-Fi 6 uses OFDMA and 1024QAM to carry more data and handle several devices on the network more efficiently than Wi-Fi 5. With a Wi-Fi 6 router this gives faster downloads and more stable connections.
AX1800 dual band: The adapter works on the 5GHz band at up to 1201Mbps and also on the 2.4GHz band, for a total rating of up to 1800Mbps. The 5GHz band gives the highest speed when the router is in range.

USB 3.0 connection: The adapter has a USB 3.0 connector, which gives the Wi-Fi 6 link the bandwidth it needs. UGREEN recommends plugging it directly into a USB 3.0 port to get the full AX1800 speed.
Built-in driver for Windows 10 and 11: On Windows 10 and Windows 11 the driver is built in, so the adapter is ready to use without downloading software.
Good to know
To reach AX1800 speed, plug the adapter directly into a USB 3.0 port and use a Wi-Fi 6 router. The speeds above are maximum link rates.
