Currently I have my netgear router inconveniently set on one side of my house upstairs. I don't want it moved and the connection to the basement and other side of the house is very weak. I want to know if I can use a WAP or a repeater/extender without creating a second wifi network. also if I use a router as a WAP, does it have to be directly wired to the primary router? I'm not experiences to networking so please explain the process to a newbie if you can.
