The Asus RT-N66U is absolutely an impressive piece of hardware. Seriously powerful, feature packed, aesthetically pleasing, and at an approachable price point for the hobbyist. I think you'll find that this holds true by reading all the great reviews here.

There are definitely two weak points to be aware of, however.

The first - the firmware that it ships with is in pretty rough shape.

After unboxing and plugging in my router I went through the setup wizard to change the SSID, change the router password, and set up WPA2 key. This went fine. After that, I went in to the router settings and made one small change, saved it, and was disconnected from the router as part of the change. It should have reconnected shortly after, but instead my browser presented me the page that comes up when a web address cannot be reached. I tried for a while but the router was suddenly inaccessible on the default IP address. Basically, from what I could tell, the change I made however benign had buggered up the router. I ended up resorting to a reset - accomplished by holding the reset button for 5-10 seconds with the router turned on.

So lesson #1 here is to immediately install the newest firmware available at the Asus website THE MOMENT you unbox your and plug in your router. The firmware update went smoothly after I got the router reset to factory setup and working again, and now it's been working flawlessly for a month.

OK, second weak point - the router, as far as I'm concerned, comes from the factory improperly configured. That is, the default settings in the router hamper its full and proper operation.

What I mean by this is that after installing the router I was getting less than ideal performance out of it.

Color Name: Black
Well, as mentioned in another review, the firmware in the initial shipment of these (3.0.0.3.72) is broken. Not buggy, not unstable, but broken. You CANNOT connect to the Internet with the factory firmware, at least in the initial release. I purchased one, returned it in exchange for another one, and the second one had the exact same problem. As discussed on this here: [...]

You must manually enter a URL [...] then change to a language other than English, then update the firmware. (The current version from the ASUS website is 3.0.0.3.90 as of 1/13/2012) Of course, that means you need to download the firmware first, since you can't connect to the Internet with the factory firmware. And of course, a router is required for most people to access the Internet, so... well, you can see where I'm going with this.

After the firmware update, things were much better. I had the Internet connection set up in a few minutes, and the speed was unbelievable. Certainly the fastest consumer wireless on the market right now. It has nice features, like 6 different SSIDs for guest networks (3 for each band.) You can choose whether or not to give those networks access to your primary network, and since you can set up multiple SSIDs, you can have different settings for each. It also has parental controls, good QoS, a VPN server and some other nice features. It supports Zoneedit for dynamic DNS, so I was pretty happy about that. (Neither the Cisco or the Linksys models I have tried do.)

One feature that's present in the Linksys E4200, but not on this router, is an SSL web GUI. I work in IT, and it bothers me administering my firewall over plaintext HTTP. Probably not that big a deal to home users, but I don't think it's that difficult to implement an HTTPS server for the admin GUI.

Dear Valued Customer,

Thank you for your feedback regarding the RT-N66u and for informing other users of this firmware issue. We are aware of the issue some users may be facing with firmware 3.0.0.3.72 and are working to have 3.0.0.3.90 installed in future shipments.

For users that have not installed the latest firmware, type http://192.168.1.1 into a web browser and enter your username and password if you have one, or enter the default username "admin" and password "admin" all lower case and without the quotations. Proceed to Advance Settings->Administration->Firmware Upgrade. Click "Check" and the router will find the latest firmware and prompt for permission to install. If this feature is not working, add the file manually from your computer.

For the latest firmware: http://www.asus.com/Networks/Wireless_Routers/RTN66U/#download
Please note it is recommended to perform the firmware update with an ethernet LAN connection between the computer.

For further questions or comments regarding the RT-N66u, please contact us at Networking_Support@asus.com

Best Regards,

Asus Networking Support

I got my shiny new RT-N66U today from Amazon.

I do networking for a living and figured even though I'd seen reports of the shipping factory firmware being broken in English mode, it would be no problem.

WHAT A PAIN!!!!!!!!!!! Come on Asus!!!!

The short and sweet version of how to get your router up and running with 3.0.0.3.72:

*Download 3.0.0.3.90 firmware from [...]
*Extract RT-N66U_3.0.0.3_90.trx to somewhere on your computer
*Log in to 192.168.1.1 (User:admin Pass:admin)
*Complete the initial setup wizard using any info you want. Just GET THROUGH IT. It will display a broken page at the end.
*Enter 192.168.1.1 in your web browser
*Click on "Administration" on the left
*Click on "Firmware Upgrade" on the top tab
*Switch the language box in the top-right-hand corner from "English" to something else. I used French.
*Upload RT-N66U_3.0.0.3_90.trx
***WAIT FOR IT TO FINISH***
*When it's complete, choose "English" again from the language drop-down.
*Go back to 192.168.1.1 and complete your initial router configuration.

The good news is that after I got 3.0.0.3.90 on the router all seems to be running smoothly.

I was replacing an ASUS RT-N56U and I have found so far:

*SIGNIFICANTLY better range on both 2.4 and 5ghz bands (Maybe 3-6db increase at an 80ft distance)

I'm hoping that when I get a wireless adapter that supports 450Mbps that I'll be able to see the huge difference.

I like the way it physically looks (Like some type of network Samurai device) and I love that I can swap out the antennas as I see fit. It looks pretty bad-ass actually.

It's been running smooth for a day now.

The specs on this thing are awesome.
