Summary: When I think of ASUS, the first thing that comes to mind are their award winning motherboards and video cards.

Summary: The ASUS RT-N56U takes router styling to a whole new level. It's slim and (we think) good looking; most importantly, it has plenty of features and performs very well. Its simultaneous dual-band Wi-Fi worked well in our tests and produced fast speeds, especially from close range. We do wish the router's Web interface was faster and a little better laid out, but you quickly get used to it.
Pros: Simultaneous dual-band Wi-Fi, Gigabit Ethernet, USB storage ports, printer sharing, good wireless speed
Cons: Web interface a little slow and takes time to get used to, power adapter is flimsy
