    Installing "Driverless" WiFi Adapter

    I bought a "driverless" WiFi adapter because my optical drive reader is not working.

    In Windows, when first plugged in, it acts as a 17MB usb flash drive that contains autoinstall executables for Windows and Mac. When executed, it no longer functions as a flash drive and only as WiFi adapter. It works perfectly.

    I also want to install it in my second laptop which runs Ubuntu. However, even after following instructions from multiple sources online, I failed to make it work. I think the problem here is that the instructions assume that the adapter is ONLY an adapter. Any help?

    The adapter has Realtek rtl8811cu.

    What instructions have you followed? Did you install the package usb_modeswitch? Did you install the appropriate Ubuntu driver for your device? Which one; a link would be very helpful. Please insert the device and run and post:

    https://github.com/brektrou/rtl8821CU this driver, with instructions in README.md. Everything went fine, but the adapter is still just a storage drive.

    Here's the lsusb output:

    Did you install the package usb-modeswitch?
    Code:
    sudo dpkg -s usb-modeswitch | grep Status
    Did you follow the other instruction from the github?
    Code:
    sudo usb_modeswitch -KW -v 0bda -p 1a2b
