I’m currently using a centrino laptop.(802.11g) I would like to use its wireless function to connect to our network, but my housemate doesn’t think it’s a good idea. He asked me to use external wireless card (he uses D-link wireless card). His reason for that is someone will steal our bandwidth if I use my centrino laptop.

I don’t understand it at all. I though they were the same (because they use the same standard). I thought its nothing to do with whatever external or internal wireless card we use, it is all about our access point setup.

Sorry for asking stupid question.
