Can't make wireless Internet connection

[tlinux]

I have a dual boot setup with Windows XP and Kubuntu 7.04. I can connect to the Internet via Windows. However, the Kubuntu 7.04 connection has stopped working. I have a Linuxant-wrapped driver. I've gone through some of the files, and with my limited knowledge of the subject, it seems that Kubuntu is recognizing my driver but isn't connecting. That's all that I can determine. I have saved four files related to this and they are shown in the following pastebins:

ifconfig: pastebin.com/m5cc281e
interfaces: pastebin.com/m46807f1d
iwconfig: pastebin.com/m11f556beb
lsub: pastebin.com/m68278d8b

Any help you can give me getting reconnected will definitely be appreciated.
