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 }}} or some editor of your choice as root) the following three files:{{{ /lib/modules/VERSION_OUTPUT_OF_COMMAND_ABOVE/modules.alias /lib/modules/VERSION_OUTPUT_OF_COMMAND_ABOVE/modules.dep /lib/modules/VERSION_OUTPUT_OF_COMMAND_ABOVE/modules.usbmap}}}Replace ''VERSION_OUTPUT_OF_COMMAND_ABOVE'' with the output of the {{{uname -r}}} command. In your editor add{{{ zd1201 }}}at the bottom of the file, if the phrase isn't in there yet. 1. Now download the 1201 Firmware from [[http://prdownloads.sourceforge.net/linux-lc100020/|Sourceforge.net]], unpack ({{{tar -xzvf}}}) zd1201--fw.tar.gz to {{{/tmp}}} and change working directory via {{{cd /tmp/zd1201--fw}}}. 1. 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.
