MODEM.
Not computer.
MODEM.
He is right.
Off Topic: I don't have a router at my mom's house, so when I want to play xbox live, I have to shut off modem, take computer cable out, put xbox cable in, turn on modem, wait a few minutes. When I want to go on computer, I do the opposite (xbox wire out, computer wire in). So, I get a new IP twice a day on average.
All you silly people with routers, you amuse me.
