I have always been using my macbook(10.6.8) as a hotspot and everything worked fine. But of recent, my iPhone and iPod just can recognize the presence of the macbook wifi but they can't connect to it. The load "spinning wheel" keeps spinning but there is no connection from my iPod or iPhone. where could the problem be?
PS: I have crosschecked again and the airport option in system preferences says "AirPort has the self-assigned IP address 169.254.17.245 and will not be able to connect to the Internet." I am not sure how to proceed from here.
