That is rather odd. LELA uses WZC (windows zero config - the little computers with the 3 circles on the right in the system tray) to set up the profile. Maybe there is some reason that this process is locked or it can't switch it over from the Linksys wireless utility?
Can you right click on the WZC thing and see the available wireless networks?
Yes, I can see my network when I click on the little computer with TWO circles on it. (is this the NZC app?) It indicates the network is ready to connect to. Is there a way to unwire the laptop manually. In that way I could see what is going wrong ?
Click on add another computer and answer the questions such you tell it that you have a non-XP computer. You will then be presented with a screen with the settings that you need that you can cut and paste into the WZC (computer thingy with the 2 circles).
