Ok, I have two macs and strangely one mac is unable to connect to the internet via airport while the other one can via airport. What gives? What I'm observing is that when I open up Network Preferences in both macs, the Airport says its connected on the working one while it says no IP Address on the one that's not working. However, when I change locations so that both macs have the same locations, the one that's not working says, Self-Assigned IP, yet, still no connection. One more thing, I also notice that in advanced settings under TCP/IP, both macs have two different IPv4's. How did this happen?
