OK. In my house we have a desktop computer with the internet. The internet is not wireless, there are cords that run in the computer. Im not too up to date on computers. So bare with me. My question is. If i buy a new computer for another room, hwo would I go about hooking the internet up to it? Its too far away to run another cable, so would I be able to install a wireless modem thing to run off the internet we already have so we dont have to pay more? thank you.
