Can't get wireless to work with kubuntu 9.04

[Bruce Bales]

Greetings -

Wireless on my laptop with kubuntu 8.04 was not easy.  I had to 
sudo iwconfig ath0 essid bbs key (the wep code)  and then 
sudo dhclient each time I booted up.  

Then I upgraded to kubuntu 9.04 and the iwconfig line no longer works.  The 
iwconfig line gives me "ath0 no such device."
I tried wlan0, wlan, eth0, ath1 and wlan1 -- same result.

Wireless was working long enough to install and update 9.04.  

The main page has an icon which says "network management"  Clicking on that 
then  "network connection" then "enable wireless"  then "manage connection" 
gets me nowhere.  

I would greatly appreciate some help on this.
