Install/patch Edimax EW-7138USG

[KingNeil]

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:

sudo modprobe rt73usb
iwconfig

Do you now have a wireless interface? Can you click the Network Manager icon and connect?

[KingNeil]

No, this is what iwconfig returns:

lo        no wireless extensions.

eth0      no wireless extensions.

wlan0     802.11b/g  Mode:Managed  Frequency=2.422 GHz  
          Access Point: Not-Associated   Bit Rate:11 Mb/s   
          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.

[chili555]

Plug the device in and do:

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.

[KingNeil]

Here is the ZIP file.

Any idea of what the problem is?

[chili555]

No ideas yet. Please post:

lsusb -v
lsmod | grep rt

Thanks.

[KingNeil]

Do I run that with the dongle plugged in?

[chili555]

Yes, please.

[KingNeil]

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