I have no idea what could that be but sometimes my MBP sees the network and is connected but doesn't load the pages. Status is "connected". when I go to network diagnostic everything lights up green down to ISP but server and network are tellow or red and I got the tab "your computer is connected maybe you typed wrong address" or something like that. Anyone have any idea what would that be?? And I can see people browsing the net next to me if its public access...frankly speaking its kind of annoying.
