Yes it would. I "connect" all the time (associate to the AP) but don't get an IP address. I end up with an APIPA address (169.254.n.n) and zero connectivity, but Windows is blissfully ignorant of that problem. In Vista you'll usually get the yellow exclamation point on the connection icon on the systray.
