My son & I want to play some head to head action here at home, not online. We are both running windows 8.1. He has an Acer M5-583P-6423 laptop & I have an HP Pavilion P6-2326s desktop. We need to go wireless because he has a gigabit port & I have regular RJ-45. I have a Belkin Wireless G MIMO router but it was used on an older pc when we used to have cable. How can I make this happen?
