    Install/patch Edimax EW-7138USG

    I have Ubuntu 9.04 and the Edimax EW-7138USG. It is a USB dongle for Wifi.

    I don't know what the name of the driver (?) is, whether it's ralink rt73, or rt73usb or what (I've heard two drivers were released for this very device, so I don't know if mine is the old or new). I need to know how to get this working on Ubuntu 9.04. I've read various guides, but none seem to work.

    Can somebody help?

    This is where I bought it: http://www.play.com/PC/PCs/-/660/867...archtype=genre

    You might try the built-in driver. Open a terminal and do:
    Code:
    sudo modprobe rt73usb
    iwconfig
    Do you now have a wireless interface? Can you click the Network Manager icon and connect?

    No, this is what iwconfig returns:

    Code:
    lo        no wireless extensions.
    
    eth0      no wireless extensions.
    
    wlan0     802.11b/g  Mode:Managed  Frequency=2.422 GHz

              Retry:on   RTS thr:off   Fragment thr:off
              Power Management:off
              Link Quality=0/100  Signal level=0 dBm  Noise level=0 dBm
              Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
              Tx excessive retries:0  Invalid misc:0   Missed beacon:0
    
    pan0      no wireless extensions.
    wlan0 is my computer's regular built-in Wifi, I think.

    I don't even know if rt73usb is actually the name of the driver... Can anyone confirm what the name is? This is very annoying.

    Plug the device in and do:
    Code:
    sudo modprobe rt73usb
    lsusb -v
    dmesg > dmesg.txt
    zip dmesg.zip dmesg.txt
    Please post the lsusb result and attach the dmesg.zip file that you will find in your home directory. Thanks.

    Do I run that with the dongle plugged in?

    It doesn't exactly all fit in the terminal window. How do I show you the output?

    EDIT: Also see the info on the next post.
