I have an old XP (Compaq, though I don't have the model # handy right now) that still works and I gave it to my oldest son for his room. His room has no Ethernet hookup as that's in the front of the house in the living room and his bedroom is at the back. I certainly do not want to go to the expense and hassle of trying to run cable through the attic to his room either. I already have a wireless router that I use for my kid's tablets and my mother's laptop. Is there some way of installing wireless hardware that would allow that old of a desktop to get Internet via wi-fi?
