I am sorry to hear that your CSL WLAN USB Adapter 300 Mbit/s is not working under Windows 11 and the driver installation is failing. This problem often occurs when the adapter is not recognised automatically or the appropriate driver is missing. - Windows Update: Make sure that your system is up to date, as Windows updates sometimes contain required drivers. - Change USB port: Try connecting the adapter to a different USB port, preferably directly to the mainboard. - Compatibility mode: If the installation still fails, try running the driver setup in compatibility mode for Windows 10 What you can also do: - Determine hardware ID - Download the appropriate driver - Install the driver manually
