How in tarnation do I do this? We have a cable modem plugged into the wall on our first floor with a WLAN cord coming out of it, which plugs into the Time Capsule. We then have an ethernet cord that goes from the Time Capsule to our old PC. How would it be possible to put a router upstairs anyway with this current situation? (WITHOUT running it all through the house and up the stairs. >_<) I see people with houses with ethernet cords upstairs, but I just have no idea how they do it. Don't they need a central area for the modem, or are modems old, phased-out tech that we still have for some reason. This is one of the things that confuses me most. Do I need an electrician or something?
