moving a computer between 2 separate networks

Hope you can help me.  My daughter often takes her computer to her boyfriends and uses his network, which has 6 computers using a network hub.  When she bring it home again, she can not log onto our network, which is only 2 computers ( including hers) and not using a hub.  Both our computers are operating on Windows xp Pro. Wehave run the network wizard countless times, making sure that both networks have the same name.   Could this be an ip address fault or is my daughters machine looking for a hub?
