I am on the Ubuntu 7.04 live cd and want to test out my wireless card. The card is identified fine and shows wireless networks but has no option for WPA-PSK. I use WPA-PSK on my linksys router but when I try to connect with my WUSB54GS I only have WEP options. It says I have the WPA supplicant when I try to install it. I am stumped on this and would appreciate help a lot.

wpasupplicant can be tricky, I suggest you do a quick Google search for easy howtos on how you configure it. Apart from that, the "availability" of WPA encryption depends on the driver Ubuntu uses (if it is or isn't capable of doing WPA) and I remember seeing a wpa option in the kernel configuration too, though I'm not sure if it affects this case even if it wasn't built.

So:
- read an existing howto (many found here or using a search engine) on how you configure and use wpasupplicant, it's not as straightforward as just using WEP
- search for something that tells if the driver you use for your card knows how to deal with WEP
- if the tool you are using doesn't seem to provide WEP key input, maybe try some other tool instead? Ubuntu 7.04's Gnome version uses the network thingie on the panel to deal with wired and wireless networks, and it can deal with WPA, but I never quite got it to work (found out the only driver that exists for my card on Linux doesn't work with WPA of any kind), and another point I found out was that the WPA box wasn't there unless the "Connect to.." dialog was opened the right way -- it makes a difference if you click on a detected network, if it's been tried to connect to earlier or if you just "connect to another network...")

thanks for the help.
