I had to reset my wireless router, and in order to do that I needed to hook up my Macbook to the router via an ethernet cable. While I was doing that, something screwy happened with my Airport. I don't know what it was, but now I've got an empty Airport icon in the menu bar, and when I click it I get a context menu saying, "Airport: Not Configured", and it's grayed out. I open Network Prefs, and Airport is marked as "Inactive", and I can't even hit the button to turn it on. This is driving me crazy, and I hope someone can help me out here. I'm running the latest Leopard on a 1.83 Ghz Macbook. Thanks to anyone who can help me out! ETA: Here's a grab of the screen.
