Problems with OS X

[asiananimal]

As of today my wireless stop working. I don't know why I'm still trying to trouble shoot it. But one thing I've notice is that at start up there is a flashing World Icon then a flashing folder icon alternating between the apple face symbol and the "?". This happends before the the gray apple start up screen. Can anybody tell me what those mean?

Thanks

Duff-Man says...that means your Startup Disk has been forgotten and it is looking for a network to boot from...go into your system preferences and reselect your startup disk and that should fix it....oh yeah!

I'm still having trouble witht he AirPort Card, it seem that it has connected witht he router but it can't get an IP from it, any suggestions to where the problem might be?

I know it's not the router problem, because my friend got on the wireless just fine.

Is there a way to reload/reset the wireless card's drivers, or is there an easy fix....what should i do
