I just set up a wireless network for my girlfriend. She just got a computer in her room but theere's no ethernet in her room. There is downstairs. So i hooked up a Linksys wirelesss router to the downstairs comp, and a wireless reciever to her computer. It hooked up and she can get on the internet. Now, how do i set it up so she can get her files from the downstairs computer to her computer?
