  • Do you mean DWA-121? Please edit your question to show the result of the terminal command: `lsusb` Welcome to Ask Ubuntu. – chili555 Mar 06 '22 at 17:29

    Probably you mean DWA-121. It should simply work out the box with *rtl8192cu, rtl8xxxu* drivers - see https://linux-hardware.org/?probe=d6c16c5786 . Which problems do you actually have? Please add output of `lsusb -t` and `lsmod | grep rtl8` with device connected. – N0rbert Mar 06 '22 at 17:48
