Try this:
$> sudo ifdown eth0
$> sudo iwconfig eth0 essid <SSID HERE>
$> sudo iwconfig eth0 channel 11 (or the channel number you want)
$> sudo iwconfig key off
If your access point is still show "invalid", then do
$> sudo iwconfig ap <ap address>
where <ap address> is the mac address of the access point you are trying 
to connect to.

and then do
$> sudo ifconfig eth0 up
$> sudo dhclient eth0

and paste the output here. Also, see what happens in /var/log/syslog 
while you are doing this.

I use KDE on my desktop (on Debian Etch). I really like KDE, it is nice. 
My wife usually uses Gnome on her laptop which has Ubuntu on it.
