Summary: This was an upgrade to my Asus RT-N56U. The 56U was running the custom Padavan Firmware...which rocked, much better performance with that firmware than stock.. That router was super fast both wifi and wired speed. Though, I do believe the 56U to be more consistent with its transfer speeds. I got a steady 20-24MB's file transfer speed in Win 8 from my file server over the 5ghz wifi(intel Advanced N 6235) and 100-113MB's over gigabit wire.
Summary: Review below Update 8/7/13 After a long wait I decided to get my AC56U through another site, all I can say is I wish I would have done it sooner. First off the router feels snappier in the gui while making changes and waiting for the router to make changes. The first thing I did after plugging it in was flash Merlins firmware onto it and setup my connection to my VPN with his added OpenVPN settings. Setup was fast and simple, wireless setup was created without a hitch.
Summary: Pros: + great 5GHz wireless speed + same SOC as the ac68u (currently the best CPU ASUS uses is in this model, which in theory should be internally faster than the lesser CPU used in the slightly more expensive and higher end AC66u) + VPN and dual WAN features, all the more advanced features of the ac68u are also in this model + I can connect at 560mb in my living room, with the router 1 floor below in my basement + real world wifi speed test around 40MB/s while connected...
Will this be the beginning of the hybrid router/NAS movement?

Summary: I just set this up to replace an E3000 as the main router. The reason for doing so is that the 5GHZ radio on the E3000 is flaky and doesn't reach my master bedroom. The router is placed at the front of the house in one bedroom with my master bedroom on the other end of a 2000 sq ft house. It's not a large distance as the house is rectangular so it's 50 feet at most, but there are walls in between. The 5GHZ radio was an epic fail on the E3000.
Summary: All I can say is wow. I don't typically leave reviews for products, but this one needed to be reviewed. I recently switched from a Linksys e1200v1 after constant connection drops in an area with high 2.4GHz interference. I hooked this router up to a Sony Vaio Pro 13 with an Intel 7260 wireless chip via the 5GHz network and was immediately blown away at the speed and range.
Summary: I installed the Asus RT-AC56U WiFi Router in late December 2013 to replace an aging Hawking HWRN2. Both 2.4 and 5.0 GHz bands performed great for the first 2 to 3 weeks. Better range provided coverage in old null spots in my large 3 story house and the 5 GHz was considerably faster. In a little over 2 weeks I began noticing my 2.4 GHz client devices were hesitating before enumerating new websites.
Summary: This router has a known issue with the 2.4Ghz channel not working properly. The 5Ghz channel works well, but the 2.4Ghz DOES NOT WORK. I have had this unit replaced with a new unit and the same thing happens. Caveat Emptor. Buyer Beware. I have attempted to have my issue resolved by working with Asus customer support, to no avail. DO NOT BUY THIS ROUTER, YOU WILL BE DISAPPOINTED!
Summary: I have owned the RT-AC56U for several months now and it has worked flawlessly on both 2.4 GHz and 5 GHz bands. I have read several reviews that mention two specific issues with this router, one being 2.4 GHz performance, and the other being range. While I experienced both of these issues early on with mine, I quickly discovered that neither were the fault of the router. Hopefully I can help a few people who are frustrated with these problems.
