    Re: LV-UW06 Wireless USB Adapter not detecting any wifi in Ubuntu 20.04 LTS in Deskt

    I suspect that the instructions you followed missed a crucial step. Please run:

    Code:
    cd ~/rtl8188fu
    sudo cp firmware/rtl8188fufw.bin /lib/firmware/rtlwifi/
    sudo modprobe -r rtl8188fu
    sudo modprobe rtl8188fu
    If the wireless is still not working, then please run the terminal commands:

    Code:
    rfkill list all
    dmesg | grep -e rtl -e wlx
    Post the result.

    Is it inserted in a USB2 or a USB3 slot? Please try USB2.

    Is this a dual boot with Windows? Is the behavior any different if you reboot from Windows or if you boot straight to Ubuntu?
