UGREEN CM496 (90339) AC650 Mbps Dual Band Wi-Fi USB Adapter

The UGREEN CM496 (90339) is a dual-band wireless USB adapter that brings fast and reliable Wi-Fi connectivity to desktop computers, laptops, or any device with a USB-A port that doesn’t have strong built-in wireless support. It supports 802.11ac Wi-Fi technology with combined speeds of up to 650 Mbps — delivering roughly 433 Mbps on the 5 GHz band for faster performance and 200 Mbps on the 2.4 GHz band for greater range and stability. This adapter uses a 6 dBi high-gain antenna to improve signal strength, extend coverage, and help maintain a stable connection even at a distance from the router. The USB 2.0 interface makes it easy to install, and most modern operating systems like Windows and Linux are supported — with plug-and-play setup on many systems or simple driver installation where needed. Security protocols such as WPA-PSK and WPA2-PSK keep your wireless connection secure, and the adapter can even operate in Soft AP mode to turn your PC into a Wi-Fi hotspot. Its compact, black design makes it super portable and ideal for enhancing wireless performance for streaming, gaming, video calls, or everyday internet use.
