ASUS EA-N66 & Amped SR20000G Wi-Fi Extender Review - Which Wireless Network Extender Is Best For You? - Legit Reviews:

"With the Holiday season fast approaching, we wanted to take a look at some devices to enhance your existing home or small business network.  Many of us are quite happy with the router that serves as the central hub, but often complain about the wireless coverage around the house or “dark-spots” in the building.  Most times, attempting to fix these Wi-Fi issues results in other issues cropping up.  For example, if you move the Wireless Router away from your home office to get better signals in the corner of your house might result in worse coverage in the bedroom.  Many of us can’t even move the router since it is hard-wired to devices that can’t be relocated."
