WPA/WPA2-Personal(PSK) Key help
I'm following the very helpful tutorial by Oxygen to try and get my desktop wireless card working. I'm running Xubuntu Edgy Eft. This is my first go with Linux, and I'm eager to learn.
I've unpacked and installed ndiswrapper successfully, and copied over the drivers from the disk that came with the card. I was unable to find out what to do with the A3AB.sys file that came on the disk, but the NetA3AB.inf file installed properly. I continued following instructions, and had nearly made it to the last section, when I ran into a problem. My card works (ie, I found the network I need to connect to), but after entering the SSID and key, the next command provided in the tutorial doesn't work on my machine.
Here is what my screen reads:

Thanks so much for your help.

(apt-get install dhcpcd)
You may have dhclient instead of dhcpcd

Yeah, there's many different ways to establish DHCP, Ubuntu generally comes with dhclient, as mentioned above.
Remember to run it as root (sudo).Graham - You'd better Use Linux!
I'm registerd Linux user #397030. What about you?
Is there a difference between sudo and su?
I've been using su without any problems, and sudo seems more complicated.
Can you explain sudo a bit for me, as compare to su?
Thanks for the advice about dhclient. I'll try it out now and let you know what happens.
Edit: Alright, I gave it a shot (well, several shots), and it doesn't seem to've worked. The "apt-get install dhcpcd" failed to find the dhcpcd package, and the dhclient failed to find...anything. When using "iwlist scan" my wireless router is still shown as the number one cell, so I know that the wireless card I installed is working properly. It's just a matter of connecting.
I started everything over (right down to reinstalling the OS), as I wanted a fresh slate now that I've got a (slightly) better understanding of what to do. Rather than the tutorial by Oxygen, I folled the installation instructions directly on the ndiswrapper wiki, which led me through a mostly similar process but with a few key differences.
In the end, I've got the card under the ath0 title now, rather than wlan0, and everything appears to be correct except for the WPA encryption key. I've no way of knowing whether that's right or not, becuase it's encrypted, and the command isn't very specific when setting it.
This is what I've got set up:
