This one has me puzzled. I am making this post through my WiFi connection on my Ubuntu 7.04 Laptop, even though the network manager says I'm not connected to anything.
I used this tutorial
on getting my Dell 1350 WiFi card driver installed and functional, but I have to type the following commands in the shell to get the card connected to my wireless network.
sudo iwconfig wlan0 essid Home
sudo dhclient wlan0
After running that, I get this output indicating that it worked.

When I try to use the GUI application that now sits on my tray, it will sit there and try to connect to 'Home' (my WiFi SSID) for a couple minutes, and then fail. When I try to connect to my wired network, it does it without a problem.
Thanks in advance for any advice.
