"Hi, I'm Jason, Mac genius, and today we're going to talk about how to connect two computers to a wireless router. We're going to start, first of all, with a wire connection. So, this cable is actually ethernet cable and if you watch any of the other videos, you're going to know this. RJ-45 connectors, that's a technical term. I'll expect you to learn that. So, I'm going to go down and plug this in to the back end of the wireless router. So, what we're doing now, this is a hardline connection. Then, up to here (plugs in). All right. And then we're going to plug into our PC like that. OK, so now you've got a wired connection. The other way you can connect -- and that's one computer. We're going to go to a second computer, a second laptop. And we're going to turn on the AirPort. Turn AirPort on. And then you're going to see, when this pops up, that we are going to choose "linksys". And you should see this populate here, a nice strong signal, which we have. So, there you have it. We've got a hardline connection with one computer, a wireless connection with another. We've got three more ports, so we could technically hardwire three more computers into this. And that's pretty much how you connect two computers to a wireless router. Thanks for watching. I'm Jason. Bye."
