Was at the pub, got a strange IP error message, started looking at the settings, stopped, went home, checked the numbers, internet w a hardline works fine, when I open up airport setup assistant it says there's no card and won't let me turn it on.
MacBook Pro 2.33 Intel Core 2 Duo,
Mac OS X (10.5.4)
Network settings says Airport is off, and It won't let me turn it on. Now what? Do I go through all those Advanced settings? I don't really know what they mean.
