An extender isn't wired to a port on the router; it picks up the router signal just like your computer does. It then rebroadcasts it in the area where it is located. Here is a manual for the one I purchased as a FYI. It will give you an idea of how easy they are to set up. Hope this helps.
It depends on the "extender" you buy. Most have several modes and most have the ability to plug in to your router with a standard Ethernet cable, which is a much more reliable arrangement if you can do it. Otherwise it becomes a "wireless repeater" grabbing the WiFi from the existing router and broadcasting it out from wherever it is.
