I'm sitting in a Hospital with a PC running XP and a macbook. The PC connected to the wifi and got an IP address. The MacBook connected earlier, but now cannot get an IP address. What can I do to debug this? Is it really that the DHCP server isn't giving the MacBook an IP address? Or is there some bug with OS X?
I have tried many diffrent things to get the MacBook to connect with no luck. Now, I just want to understand what is actually happening.
