My father just got a new computer. This computer is going downstairs. He is giving me his old eMachines computer for my room upstairs. The computer he got has a built in wireless router. I have a wireless router for the eMachines computer. We have cable and a modem for the downstair new computer.
Now, how do I use the eMachines computer upstairs and get internet access using the wireless router to connect to the modem downstairs?
