Have you guys tried the ctrl-Funct F11 toggle.
It's in the owners manual, and I don't remember it exactly, but I believe that function-F11 toggles the power on and off to the wireless card, and toggles the LED to show when it it powered on.
As for the G-EZ Link utility, if you want it to negotiate the WiFi instead of Windows, then you need to go into the Windows properties for the WiFi adapter and uncheck the box that says "let Windows manage my connection".
Then the G-EZ Link utility will be able to save the password and log in for you when the system boots up. If you leave the option on for Windows to manage the WiFi, then theses two utilities will step all over each other and I don't think either will connect to the network at all.
But first, make sure that it is powered on using the funct-F11 key, then look into the drivers.
