Can I use an access point at a distance from the router?

I apologize in advance for being pretty ignorant about networks.  I have moved into a house that has ethernet cabling installed, but not everywhere I need network access.  The router supplied by the ISP is in one room and cannot be moved because that is the only place it can connect to the ISP's incoming cable.  I am looking at access points (e.g., Netgear WAC104) but everything I read says the AP has to be plugged directly into the router.  What I want to do is plug the AP into a network port at the other end of the house and use it to provide WiFi to that part of the house (where there is only the one ethernet port).  I essentially want to extend the ISP router's WiFi signal to dead spots using the AP and router both connected to ethernet ports at opposite ends of the house.  Is that possible?

If the home has ethernet ran throughout the house and that ethernet is connected back to the router, then you can connect an access point to it.
