I just bought myself a macbook pro, and I'm new to the mac world so I might seem like a noob to you guys. Before, I had a pc, which was connected to a router with another pc in order to be connected to the www. But now that I connect my mac and a pc to the router, an IP conflict occurs and none, sometimes just one can be connected to the web. It's an old-school router with cables (simple stuf). How do I solve this problem, so both mac and pc can be online?
