My macbook connects to my wifi connection which is secured without any issues. However it wont let me connect to the internet. I keep getting a message on the airport icon that has an exclamation point on it that says "no internet connection available." Also, when I open up the network settings under the airport settings, it says self assigned ip address can not connect to internet. I have no idea what is going on because all of my other computers and xbox is connecting to the internet just fine. I already tried to restart the router and the modem and I also emptied the cache on the macbook. I tried to call Comcast but they were not very helpful.
