Hey, I just got my first mac (MBP) yesterday. I started it up and did everything it told me to do. I then tried to get on the internet and it worked for about 10 minutes. Then it said "you are not connected to the internet" and a box showed up saying " Another device on the network is using your computer's IP address" and then suggestions of what I can do. Every once in a while the internet will work, but it quits after 5 or so minutes. I moved from Dell to Mac and I checked the IP address on those and they were not the same number... any help is appreciated! thanks!!!
