The LevelOne 11Mbps Wireless USB Adapter is a USB network adapter designed to allow a computer or device to connect to wireless networks (Wi-Fi) using the 802.11b standard, which supports data rates of up to 11Mbps (megabits per second). This type of adapter was common in earlier wireless networking setups, before higher-speed standards like 802.11g, 802.11n, and 802.11ac became widespread.
The Windows driver for this adapter enables your operating system to communicate with the hardware, allowing it to connect to wireless networks and perform tasks like browsing the internet, streaming, or file sharing over Wi-Fi.
