Reset your modem. It often happens to me, and that's an insta-fix. Just make sure you are already on the multiplayer menu.
The way to work out if It worked or not is on the top right of the screen is a set of numbers. I can't remember what they are but they should change when you load up multiplayer/zombies. If they don't change, reset the modem and they should change when you sign back in.
