How do you ask your mother for the router log-in details?

I'm trying to help my friend Pete set up a Minecraft server that's running on his mother's home webserver. I've asked Pete to check his router settings, but he doesn't know the password to their router. I've asked him to put his mother onto ventrilo so we can get down to some real troubleshooting, but he keeps deflecting. What can I do from my end? I just want to play Minecraft.
