How to get a Launchd to wait at startup

I have a script that changes the root password. It pulls the new password down from a web page (SSL encrypted). I use launchd to run the script every hour. It also tries to run it at startup. However, I think it is trying to run the script before it has network access. How can I have launchd wait for the network? I think it would be an environmental variable that requires the network, but I'm not too sure. I use Lingon to make my launchd items. Here is the launchd I use.
