I just received a MBP and am having problems connecting to local wireless networks. Airport says it is connected at full strength but I am unable to use safari. Each time I try, safari tells me it was unable to connect to the internet. When I looked under the airport status it told me that it is connected to the network but has a self assigned IP address and may not be able to work properly. This is my first mac so any help would be great! Thanks, in advance, for your help!
