I basically am looking to improve the reach of my wifi signal by using something that I can plug an ethernet cable from the wall into, which transmits the wireless signal in another part of the house. I don't want to use a wireless repeater such as this: https://www.amazon.com/NETGEAR-Wi-Fi-Extender-Essentials-EX2700/dp/B00L0YLRUW/ref=sr_1_1?s=pc&ie=UTF8&qid=1483680877&sr=1-1&keywords=range+extenders
What is the thing that I'm looking for called? Do I need to buy a second router in order to transmit my wireless signal from another source besides the one provided by my ISP?
