UGREEN CM448 (20204) 650 Mbps Dual Band Wi-Fi USB Adapter

The UGREEN CM448 (20204) is a dual-band Wi-Fi USB adapter designed to quickly add or upgrade wireless internet connectivity on desktop computers, laptops, or other USB-equipped devices that lack strong built-in Wi-Fi. It connects via a USB 2.0 port and uses a Realtek RTL8811CU chipset with an integrated PIFA antenna to deliver up to 650 Mbps combined wireless speed across both 2.4 GHz (≈200 Mbps) and 5 GHz (≈433 Mbps) bands, helping you enjoy smoother web browsing, HD video streaming, online gaming, file downloads, and video calls with less interference and better stability than older single-band adapters. The CM448 supports modern IEEE 802.11a/b/g/n/ac Wi-Fi standards for broad compatibility and can also operate in Station Mode to connect to an existing Wi-Fi network or in Soft AP (hotspot) Mode to share a wired connection as a Wi-Fi access point. It offers plug-and-play convenience on recent Windows versions and driver support for other systems including macOS and Linux. With its compact, low-profile black design and LED status indicator, the UGREEN CM448 is a practical, portable solution for enhancing wireless connectivity on systems where Wi-Fi is weak or unavailable.
