NETGEAR Universal Wi-Fi Dual-Band Range Extender: Add some extra power to your existing network and access the Internet in areas of your home that were once dead zones. The FastLane feature of this universal range extender offers high-speed Wi-Fi over a single band, which makes for quick and consistent HD gaming and video streaming.
I live in a large beach front building and we have wifi available but only laptops are able to bring in a strong signal. Other devices such as phones and game consoles lack the necessary antenna strength. The Netgear extender picks up the signal and redistributes it throughout our condo. It's rather easy to setup and does exactly as advertised.
What's great about it: Ease of use, strong signal, good price
What's not so great: Occasionally the admin is difficult to pull up
