The ASUS RT-N56U is a nice looking piece of hardware. It also can perform for you within certain limitations. These limitations seem to be range and penetration (of walls etc.). As long as you are inside the line of site you can maintain great connection speeds and also excellent throughput. It is when you break that line of site that we have an issue.
Still, considering this is a piece of hardware that would look good in an exposed area in your house, you might be able to get away with having it out in the open. On the UI and feature side the RT-N56U has plenty to help make this one of the more versatile wireless routers we have tested. The UI itself is designed with the consumer in mind. They have kept things simple so that almost anyone can work it. Outside of that the network map page is good for seeing the status of your network at any time.
I have to say that while I like the flexibility of your more traditional Web UIs, I do like the streamlined flavor that ASUS has. Of course, for the traditionalist there are still the advanced pages for you to work with. Overall, the RT-N56U is a great product at a good price.
