    I have a Macbook pro that I purchased about 3 years ago. Out of the box the internet worked fine with our home wireless router and my wife and I were able each be on our mac laptops at the same time. Recently I had an issue where the screen on the Macbook went blank but I could hear the machine running. I took it to a knowledge bar and they fixed it for free because apparently the video cards for macbooks built between 2007-2008 were failing. Once I got it back the internet would not work on the laptop. The wireless signal indicator shows full signal but when I try to go to a webpage I get the "You are not connected to the Internet" message.

    I have tried setting up my network preferences to match those on my wife's macbook which is currently working. When I go under Advanced to the TCP/IP section, I copy the IPv4 Address from the wife's laptop and use it for mine. BUt then I get the message that I cant use that address because it is already in use. Can someone tell me how to fix the connection issue so both laptops can be used at the same time?

    Not an expert here but I remember having a similar problem a while back...
    The thing that worked for me was to delete my profile/settings for the network, then restart. After that, go in and rejoin your network using all brand new entries. And no, you cannot use the same iPv4 address your wifes laptop is using.
    Give that a try.

    If you have copied the IPv4 address from your wife's Mac, then it will not work. Either us another end number on the IPv4 address you copied, or change the wife's Mac's IPv4 address.

    Example: wife's Mac's IPv4 address is, change the 3 to a 4 or 5 or any number till 255
    The same IP can only be used once within the same network, therefore the router has another IP than your wife's Mac.
