According to the compatability page, all you need to do is insert the device and open a terminal and do:
sudo modprobe rt73usb
iwconfigDo you see a wireless interface now? Can you click the Network Manager icon and connect (he asks, optimistically)?

The manual configuration tools, dhclient, etc., don't work very well with Network Manager. It's like two people pulling on the steering wheel at once!

Please click the Network Manager icon, select your network, put in your WEP key, most likely in 'WEP 40/128-bit HEX' and see if you can connect.

Just in case any other newcomer comes across this thread, the Edimax EW-7318Ug USB wireless adaptor works out of the box in both Jaunty and Karmic. You don't have to do any modprobing, iwconfig-ing, installing drivers or anything like that. At least not in this household you don't. :wink:

Click on the network-manager at top-right of the desktop. Select your network, type in your WEP/WPA key where prompted and enjoy surfing the internet.

There - easier than Windows! :p

Yes, I know. It's a common misconception that in Linux you have to type a whole load of gobbledegook into a terminal to get anything to work. It comes as quite a shock when people find that configuring wireless can be easier that in certain other proprietary OSs we could mention. :p

I hope you don't think that I was getting at you. Far from it. Although some wireless chipsets are still a pain to configure, it's a fact that with most you just have to do what I described. It always pains me to see people unfamiliar with Ubuntu getting in a muddle with wireless devices that 'just work' - hence my post.

Enjoy your Ubuntu-ing! :)
