So I wake up this morning and the MB wouldn't wake up from sleep. I restarted and it wasn't connected to the internet. I tried restarting the router, and restarting airport and still nothing. I get nothing. I connect via ethernet cable and still can't get any connection out of it. I run the assistant, but that doens't help either. I don't know what else there is to do... Has anyone heard of a problem like this? In Network preferences, I see the IPv4 address, but don't really recognize it, and the subnet mask seems to be different that what it was. I tried inputting what I thought it used to be but still nothing. Any ideas? Could my airport card thingy have died?
