Asus RT-N66U Wi-Fi Router Review

We have a new champion

FOR THE FIRST TIME in a very long time, our Best of the Best pick in the wireless router category does not bear the Netgear brand. Asus’s new RT-N66U not only beats Netgear’s WNDR-4500 in almost every benchmark, it also delivers more features, a better user interface, and a more attractive industrial design.

Let’s examine the feature set first. Like the WNDR-4500, the RT-N66U is a dual-band model capable of supporting three 150Mb/s data streams simultaneously (450Mb/s on both the 2.4- and 5GHz frequency bands). Unlike Netgear’s router, the RT-N66U delivers external antennas that can be removed and upgraded—a feature that has become uncommon on mainstream wireless routers. The external antennas helped Asus’s router deliver fantastic range: The RT-N66U delivered more than double the throughput when our test client was outdoors at its farthest distance from the router.

Satin-black diamond plate renders the Asus RT-N66U much less garish than the earlier RT-N66U.

Also like the WNDR-4500, the RT-N66U is outfitted with dual USB 2.0 ports, so it can share both a printer and a storage device on your network. But you can also plug a 3G modem into one of those USB ports, and the router will automatically switch over to that device if your cable or DSL connection goes down. The RT-N66U comes with a DLNA-compliant server, so you can stream media from an attached storage device to any DLNA-compliant device on your network (PCs, AV receivers, Blu-ray players, TVs, and so on). But Asus goes further than Netgear by also providing iTunes, Samba, and FTP servers. The presence of all these great features, however, leaves us doubly disappointed with the quality of the user manual: It doesn’t provide details on how to configure any of them.

The RT-N66U is weak when it comes to quality-of-service settings. The “automatic” QoS mode simply activates a generic rule that gaming and web-browsing activities will be assigned higher priority than peer-to-peer applications, such as BitTorrent. While you can define custom QoS rules of your own, the rules involve establishing minimum and maximum bandwidth limits for each application. The more conventional approach is to establish priority for services relative to each other (e.g., BitTorrent gets lower priority than video streaming). We also prefer Netgear’s approach to traffic monitoring, which lets you establish hard limits for bandwidth consumption and has the router send you an email message when you approach them. The RT-N66U’s traffic manager produces pretty graphs, but they’re pretty useless when it comes to stopping you from exceeding a bandwidth cap. If you care about parental controls (we don’t), you’ll be disappointed in what Asus has to offer: All you can do is turn Internet access on or off according to a schedule.

But we have no complaints when it comes to wireless throughput. On the 2.4GHz band, the RT-N66U beat the WNDR4500 by a considerable margin in every test location except the bedroom, where the client is closest to the router. We experienced similar results on the 5GHz frequency band, although the Asus didn’t perform as well when the client was outdoors: The RT-N66U was quite a bit slower than the WNDR4500 when the client was on the patio, and it was only slightly faster when the client was at our farthest test location.

If you’re looking for a fast, USB-equipped wireless router, the Asus RT-N66U is the one to buy.

The August 2014 issue has the Linksys WRT1900AC as being the "new king" for wireless routers. I read this article when it came out and had forgotten the model. I checked the site to see this one listed and knew it was not the one from the magazine. It just reminds me that no one is maintaining the website to keep it current.

I have had my WNDR4500 for 1 year and 4 months, based upon the previous MaximumPC recommendation, and I bumped the power cable on the unit. Stupid me because apparently bumping the power chord caused firmware corruption which in turn required a lot of manual effort to get the unit back into operation. The Power LED still does not blink correctly so I decided to reach out to tech support.
Upon reaching tech support, not only did the repeatedly not bother to read what I wrote them, but their attitude was "well... you are past your warranty period so go buy a new one".

So I am VERY glad to find your article here saying Netgear has been replaced as the best of the best for wireless networking. It's incredibly hard though to find out through Asus's site what type of warranty this unit comes with. I think I found through random searches that their unites come with a 2 year warranty, which as far as I am concerned is 100% better than Netgear. If you could confirm this, I would really appreciate it.

Also do you know if this unit has an Access Point feature like the WNDR4500 does? That worked well with my ISP supplied and mandated router in that I was able to get pretty much all of the other features of the WNDR4500 I wanted w/o using as my main router.

Your WNDR4500 should not be out of warranty if you only bought it that long ago. This is from Netgear web site...

Below are list of Home routers that have Limited Lifetime warranty:
•WNR1000v3 (purchased on or after November 1, 2011)
•WNR2000 (all versions, purchased on or after October 1, 2009)
•WNDR3400 (all versions, purchased on or after January 9, 2011)
•WNDR4000 (purchased on or after July 1, 2011)

By what you posted you bought the WNDR4500 about April 2012 well within the time to qualify for the hardware lifetime warranty.

I have always had good luck with Netgear products (never needed support till recently, will see how that goes). I am looking forward to see how the Asus RT-N66U compares to the Netgear Nighthawk AC1900. Come on MaximumPC compare away so I know which is my new router.

According to their tech support and the documentation that came with my unit, it's a 1 year warranty.

Either way simply bumping the power chord shouldn't have caused a firmware corruption, and even if it did I should have been able to recover the unit back to normal operating status with all the work that went into it. So I am pretty much done with NetGear at this point.
