Summary: The router died within 4 months. I sent the router for repair, but when I received the same router after repair(?), it still had the same problem. I still have the non-working router on my floor, and I am not getting anywhere with the customer support.
Excerpt: When I bought this router I had just gotten an asus board and loved the quality and figured if they can do this here they should hopefully make a good router. I was right. This thing is 1 yr and 9 months so far and shows no signs of going down.
This is a nice router that will do what you need it to with a bit of effort on your part

Excerpt: The date of purchase and purchase price are an approximation. Let me start out with the good. This router is fast. I live in a small, 2 story, 3 bedroom house and I have this router by my modem in the living room. My Internet speed is 30 Mbps. This router adequately handles that.
Summary: I purchased the ASUS RT-N56U because of reviews I read and that I figured Asus was a good company (I have owned their motherboards for years). This router has had problems from day 1. I had 3 support tickets while it was in warranty, and the company would not replace it.
Summary: This router drops internet signal at random times throughout the day, have to try to reboot to fix the problem, and sometimes it doesn't even work. It seems like this unit can't handle many wireless clients... There are decreases in speed for no real reason with this router at certain times.
Horrible ASUS firmware prevents basic proper operation!

Summary: Buyer beware, even the most current ASUS firmware for this router will cause your long-running SSH connections (specifically for me, large capistrano/Rails deployments). Setting TCPKeepalive/ServerAliveInterval/ClientAliveInterval will not help, since the problem seems to be with the ASUS firmware...
Summary: I purchased this router during November, 2011. This router completely stopped working in May 2012. Need I say more ? Luckily, our travel wireless router is providing internet access until I replace the ASUS Black Diamond router.
Summary: In the last week or so, I've had two of these. The first one set-up easily, and seemed to be working fine, but when I went to unplug it to move it to a new location, the power supply literally fell apart in my hand. So I returned the router and got another one.
Summary: Do not buy this router if you want to use a soft phone. It's also really slow. I tried for two months to get this router working with my soft phone, and it would never work properly -- took over a minute to register and at least that long to complete a call once dialed.
