    Every couple of days my computer (13 inch macbook pro) will disconnect from the Internet giving me a pop up saying 'another device on the network is using your computers IP address' it later says to change my IP address but I don't have one because I have an airport express router. What can I do about this?

    Do you have any other computers accessing the wireless network the AirPort Express transmits? And you can change the IP address of your Mac via System Preferences > Network > AirPort > Advanced > TCP/IP > Configure IPv4 > Using DHCP with manual address.
