auto connect internet

I have a macbook pro and when I shut the lid and put it to sleep, the computer will fall asleep (like its suppose to). When I lift the lid and leopard "wakes" up, I have to manually connect to the internet again. Does anybody know how to change a setting or get a program that will allow me not to have to reconnect every time I put my computer to sleep?

See if this helps you out:-

Nevermind, OP fixed his problem.

If you're connected wirelessly you have to select the default network otherwise it will ask you every time.
