MacBook Pro :: Does Not Recognize Ethernet Cable Or Connect To WirelessMay 4, 2012
Today when I turned on my computer, it suddenly would not recognize any kind of Internet connection. The Ethernet cable that I use every day now shows up as 'unplugged' even though it is plugged in. I have tried using a different cable, and it still shows up as unplugged. When I try to connect to the Internet wirelessly, there is always a connection timeout and I can't connect. I use a self-assigned IP address and I've never had this problem before. I've also reset my PRAM, but it hasn't worked.
