I have a router/modem connected to my laptop and the wireless light is lit on the router. I have a network adapter in my laptop but I don't know how to make it wireless. Even the tech from Verizon who was here installing the router didn't know how to do it. So I use it wired which is fine. However, I am thinking of buying a tablet and wonder if I could set the tablet up for wireless since I have the router while at the same time leaving the laptop wired. Or do you have to have both the same?
