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 have a complex home network with 8 PCs, 2 printers, DVR, Slingbox, IP hardphone and two wireless networks to span the entire house (3,400 sq ft).
This router is easy to configure. Bascially, it creates a duplicate of your existing wireless network with the same seetings except for a different SSID. The signal produced covers a large area and is reliable and fast.
What's great about it: Strong signal, easy configuration, good price
What's not so great: Can't remotely manage router settings -- must have hard-wire connection
