  1. Check if zd1201 module is already loaded by typing the following command in a terminal:

    sudo lsmod | grep zd1201

    Output should be something like:

    zd1201                 22660  0
    usbcore               130692  4 zd1201,ehci_hcd,uhci_hcd

    If the output is empty you have to load the module by the following: type uname -r, the output shows your kernel version. Now you have to edit (sudo gedit <filename> or some editor of your choice as root) the following three files:


    Replace VERSION_OUTPUT_OF_COMMAND_ABOVE with the output of the uname -r command. In your editor add

    at the bottom of the file, if the phrase isn't in there yet.
  2. Now download the 1201 Firmware from, unpack (tar -xzvf) zd1201-<version>-fw.tar.gz to /tmp and change working directory via cd /tmp/zd1201-<version>-fw.

  3. Last but not least you have to copy the firmware files to /lib/firmware by

    sudo cp -p -f zd1201*.fw /lib/firmware

    Now plugin your WLAn adapter. iwconfig should list the adapter in it's output.
