My boss, against my advice, got a Mac Laptop and we are having trouble getting his laptop to work on our network. His computer can connect to the wireless router and he shows up on the network, but he can't open any broswers or check his email, it's like he's on the network but he doesn't have an internet connection. I have tried manually entering an IP address, and I have tried to have the router assign it one, and neither has worked. Don't know what else to do, any suggestions?
