| | GoWifi's solution still works
I've finally gotten past the "acquiring network address" problem. My problem was just like Mr. Pooper's. And I did the GoWifi solution.
I just needed to update the driver for my laptop's Dell wireless card (to the latest driver available from Dell's site.)
Then when I tried to connect again, the acquiring network address message only came up for about 5 seconds, then I was connected.
