Summary: In box directions absolutely horrible. Asus support terrible. I got how to set it up from YouTube!! Finally got it connected and my internet speed went down by 50%. I set it up as an extender which should have increased my connection, but it had the reverse affect. I would not recommend this to anyone, exp. someone that is not computer savvy.
Don't buy if you want to use as a network repeater

Summary: This unit is a nightmare. I have two other ASUS wireless units (ASUS ASUS RT-AC66U Router and ASUS (RT-N12/B) Wireless-N 300 using in repeater mode) and I love them both and have been giving me flawless performance for almost a year. The tech support with ASUS has been good (no complaints). So I thought I would add a second unit to act as a second repeater for my home (router in home office sep building).
Summary: I followed the instructions (including updating the firmware, though that was not in the instructions), but was not able to establish a 5 GHz connection. I contacted product support and followed their instructions but was not able to establish a 5 GHz connection. I received an RMA from ASUS, sent in the old unit, got a new unit, followed the instructions (including updating the firmware, though that was not in the instructions), and was not able to establish a 5 GHz...
Slow, unresponsive UI. Pain in the rear to set up. Causes problems.

Summary: I purchased this item thinking it could simultaneously act as a adapter and an access point with the intent to connect my computer to the wireless network and allow my mobile devices to have a closer access point. You can't do that. It's either/or, not both. You can set the device up as an access point, as a repeater or as an adapter. To configure the device you must log in to a website (or connect directly through IP) while connected to the device itself.
Works well, but advertising makes it sound like it will do 2.4GHz AND 5GHz - it won't. It will do one or the other. May Need TWO

Summary: I set this up in extender mode and found that it was only extending the 2.4 GHz band, not the 5GHz band. I sent an email to ASUS, who informed me it will do one or the other, but NOT BOTH AT THE SAME TIME. I've had units much cheaper than this that could do both. If you look at the description they have on their website, they make it sound like it will do both simultaneously.
Range extender non-responsive; ASUS support non-responsive

Summary: We purchased two of these devices to extend our wifi network across the entire floor of our building. We are using the ASUS RT-N66U as the Access Point, but not DHCP server. After spending several hours trying to get the ASUS EA-N66 configured as a range extender we gave up. We updated the firmware on both the router and range extender, if it was needed. The problem was two fold. It would not communicate correctly with the router and DHCP server to obtain an IP address.
Summary: It is an Ethernet adapter so you can use it as a bridge, I’m successfully using it as a Wireless Bridge, it is connected to a gigabit switch and 4 devices are currently working perfectly fine, but don’t tell support that! I called in to try to get help configuring it to have an IP address on my network so I can remotely connect to it and configure it.
Pros: It's fast! Doubled by file transfer speed versus my previous 802.11N 300Mbps. (Using Windows file copy)
Cons: Poor GUI (Interface). Doesn’t allow you to do a site survey after the setup, to switch to a different access point you have to do the setup all over again and for some reason that takes 4 to 6+ minutes to complete setup. Doesn’t show you signal strength or your connection speed. Can’t configure IP address of the device to a IP address on your network STATIC or DHCP. Poor support.
