Something has changed.  Now the machine accepts 
sudo iwconfig wlan0 essid bbs key (the wep code), but when I 
sudo dhclient  It does DHCPDISCOVER wlan0, pan0, eth0 and wmaster0 on port 67 
(about 20 lines) with various intervals.  Eventually it declares 
No DHCPOFFERS and goes to sleep.

But then I went to network manager and clicked on wireless, did a few other 
clicks and put in the wep key again and now konqueror works.

Nothing changed, but it works.  The machine has aptly demonstrated its 
superiority over man.  It will help you if it feels like it.

Somewhat embarrassing.  Thanks to everyone for the help.
