Hi all Need some help troubleshooting a strange issue. This afternoon my Macbook Pro lost all internet connectivity. I can see wireless networks, connect to the networks, pull an IP address, but when I open Safari or Firefox it will not open any websites. iTunes or the App store will not load either. I've checked the hosts file to make sure nothing has been changed and it looks clean. There aren't any proxy settings in the browsers or under Network connections setup either. I run Norton AntiVirus (free form Comcast) and nothing strange has popped up there either. At the suggestion of a couple of other forums and posts I've reset the SMC and PRAM and that did not help. Does anyone have any suggestions on where else to look and what else to try? I'd like to resolve without reloading the OS if at all possible.
