Going Wireless Need Help

[ktorrresxiii]

Hey everyone, a friend and I are starting to conceptualize a computer when we hit one road block: my friend doesn't have a broadband connection anywhere near her room.

From there we decided we'd make her computer wireless, however I don't know how to do that. So when I did a little bit of searching, my understanding is that Wireless Network Adapters are needed to make a desktop wireless. Other than that there is also Wireless Access Points.

Can anyone recommend any wireless network cards that will be suitable for gaming, or if wireless access points are better?

Thanks everyone
