hey i always wanted to know/do this. i have around 4 computers in my house, 2 of them have windows xp and the other 2 have windows 7. my question is, can file share from one computer to another through my router?
Yes, you can file share. Basically you just have to set things up for it. All computers need to be on the same workgroup. You can run the small office network setup wizard on the XP computers.
