Gigabit Wireless? Five 802.11ac Routers, Benchmarked
By

Our first glimpse into the performance of our six contestants reveals some interesting points. The most obvious question is: what the heck happened to Belkin? We thought this must be a fluke of some sort, but subsequent tests across this and other benchmarks corroborated our first impression. The AC1200 DB is not only crippled by its dual-antenna design, it’s not even able to perform at 802.11g levels. As mentioned previously, we got Belkin tech support on the phone, walked through all of the settings, and so forth, but there was no help for it. Belkin has an improved design in the works, and we hope to test that at some point, but for now...consider our data an object lesson in why you want your WLAN gear well-reviewed and utilizing 3x3 antenna tech. Alas, the AC1200 DB would get spanked by many 10-year-old 802.11g routers.

While we’re on the 3x3 subject, check out AirLive. By bringing beamforming onboard, the $116 N450R pulls in some remarkable results for being "just" 5 GHz 802.11n. In one direction, it even outperforms the Buffalo 11ac router. Overall, the N450R still trails every 11ac router (except Belkin), but not by much. On a performance per dollar basis, in this location and application, the N450R definitely provides a pleasant surprise, if not new legs for the current-gen tech.

Keep in mind that this is our same-room test, which theoretically should reflect optimal conditions. However, as we step back to 2.4 GHz 802.11n, transfer performance plummets. Look at the difference in uplink speed for Netgear. That's a difference greater than 600%! What causes such a drastic change? Yes, we found between four and seven competing networks in our airspace at any given time during testing, but these were fairly faint. Moreover, AirLive actually does its 2.4 GHz work with only a 2x2 antenna setup, and it still manages to trounce every competitor except Asus. That’s insane. How the likes of Linksys and Netgear, both of which were double-checked on this test, could pull in such embarrassing numbers is a mystery. Suffice it to say that we have renewed respect for Asus' product engineering and AirLive’s beamforming implementation.

As we switch to our 5.0 GHZ distance test, the tide turns. We’ve actually seen many routers over the years fail across this distance in this location. Like Belkin's solution, older hardware often won't connect at all. So, the fact that we’re measuring triple-digit Mb/s results from the four real 11ac competitors strikes us as miraculous. Also consider how little throughput loss there is between our two locations. We’re used to seeing 60% to 80% loss in these circumstances, but the 11ac routers shed almost no performance at all, and in some cases do even better at distance.

Yes, it’s great that AirLive can still pull in enough average throughput to sustain multiple HD video feeds, a feat we would not have expected, but its rivals are hitting numbers three times larger. This blows us away. This chart alone makes us want to recommend 802.11ac without reservation.

Our 2.4 GHz cross-house test doesn’t surprise. Again, Asus and AirLive dominate, Belkin can’t connect, and the other three limp by. Later on, we’ll get a better idea of what’s happening to stream integrity during these diminished transfers. Hint: It’s not pretty.

    "Folks, the time to start your 802.11ac adoption is now."

    I think this review proved that it is time to wait for 2nd generation wireless AC routers to appear before rushing to purchase.

    I've tested both the R6300 and the RT-AC66U in my home. The R6300 beats it hands down. The average homes won't have the traffic that your artificial software creates. Even your tests show that R6300 in 5ghz mode is faster. People will buy these for gaming and HD movie viewing and the R6300 has better range as well. I've paired my R6300 with an ASUS PCE-AC66 desktop wireless AC adapter and I can acheive 30 MB/S (megabytes) to my HTPC in a 2 story house. That's an insane speed. The RT-AC66U only managed about 15 to 18 MB/s. Also make sure the R6300 has the latest firmware, which is V1.0.2.38_1.0.33. But in conclusion, the R6300 and the RT-AC66U are like a SRT Viper and ZR1 Vette. They are both great pieces of hardware to fit most users needs. Get the ASUS If you got a ton of traffic and a lot of 2.4 ghz devices. Grab the R6300 if you are looking for a friendly setup, max speed, and max range.

    I'd be happy with a 2Mb/s connection. It'd be better than this horrible 512 Kb/s connection I have now. At least then, I may actually be able to watch youtube vids in 360p.

    Here's the gist of what I typed before it was rudely vaporized.

    I have a dual-band router (Netgear N600). I also purchased a couple of dual-band client USB adapters Linksys AE2500 or something to that effect.

    So the USB adapter works fine for a desktop, but having that crap sticking out the side of a laptop, netbook or tablet? Busted in 10 minutes. I hooked one up to my netbook and fried it within a couple of weeks because I'm a Netbook in bed guy. You wouldn't think it could get so hot from a USB port but it does.

    So the reality is that you have all these devices that can't be upgraded to dual-band and enjoy very little if any benefit from the new-fangled dual-band router.

    The other beef I have with routers is that they're terrible with the way they split up bandwidth between multiple devices. Instead of responsively reassigning bandwidth to the device that needs it, the router continues to reserve a major slice for a device that I'm not using.

    If you live in an apartment building, it's actually rather rude to use the full 300Mbps capacity of the wireless N band, since you may well succeed in effectively shutting your neighbor down. There's so much happening in the 2.4GHz band nowadays, it's unreal. Your own cordless keyboards/mice/controllers etc can malfunction from being unable to get a packet in edgewise.

    For these dual-band routers to be really useful, we need manufacturers of smartphones, tablets, laptops, netbook and such to build dual-band clients into them because adding the functionality with some sort of dongle just doesn't work.

    my wireless N produces 300 Megabits which would equal around 37 Megabytes. My highspeed internet doesn't come cloe to reaching 37 megabytes and i don't transfer tons of files wirelesly and my wi-fi rangs is pretty good .So i'm perfectly fine with my 300MB N wireless router right now. Besides that none of my devices spport ac anyhow so it would get bottlenecked from reaching its full potential.

    What were they using for a wireless network adapter on the client side?

    Exactly. The 'client' adapter they used if anyone didn't catch it was a Cisco/Linksys router-sized device. Not practical by any means. It'd be totally insane to make any product recommendations prior to real client adapters being available, or more accurately, embedded ones are available. I think a wireless salesman wrote this article.

    The Scion of BalanceDo the graphs really meant Mb/s? If so, isn't it still very slow?

    No actually , If you transfer from hardrive to hardrive you probably get a max output of 45MB/s The asus is close to 35MB/s wich is almost maxing out ur drives power. Ofcourse if you have a good performance you can get upto 80MB/s or a little more Not counting SSD to SSD transfer rates- Also remember that you will be able to transfer 4k HD content with the same amount of data that 1080p took

    I have the Asus RTN66U... so when does the Tomato firmware that swaps it out to RT-AC66U capability get released? :p 

    Shibby save us with another awesome tomato release!

    Probably so. However, on the graph it's written Mb(Megabits), not MB(Megabytes). Since tehnically 8b=1B, 35Mb/s=4.38MB/s and that's very slow. That's why I asked if the graph meant Mb/s or MB/s.

    I wonder which option is better in terms of performance/price ratio between 802.11ac and powerline networking. It seems that you still need 802.11ac compatible wireless adapter in each device (PC, tablet, etc.) to take advantage of the "gigabit" connection, which means the total cost of 802.11ac will be much higher than the router price. On the other hand, from mid- to high-end powerline networking may provide similar performance or better with less cost, if not concerned about smartphone/tablet. But those devices need relatively low bandwidth than PC/laptops, so they can work just fine with existing 80.11n router. Of course powerline networking has serious disadvantage of no or limited portability/expandibility. But in a regular household, it's not big a deal because you don't add additional devices every year or two in normal circumstances.

    Are all these routers fully backwards compatible? I would assume so... Anyway I would have like to seen results with some other devices running b/g/n adapters.

    Most networks - in my experience - are some sort of hodgepodge of different devices. So ac speeds are only really relevant if the results also translate over to the other spaces.

    Hey William, I have a few questions for a followup article:
    1) Wired performance: All of these things sport wired gigabit connectivity, but as with wireless we all know that wired performance can have wired bottlenecks and problems of its own. I am sure they are all better than wireless or 100/t... but what kind of throughput are we talking about? Personally (and I know I am not alone on this), I like wireless for portable devices, but for something that never moves like a TV or a PC it is really not that much extra effort to run a line under carpet or through a vent.
    -Specifically I am curious to know if any of these routers can run their ethernet in a gang mode so that I can have 2 gigabit lines to a server, and 2 lines to my PC (and 1 line to my wife's PC) so I can have enough throughput to offload all of my HDDs to a central location and have a truly silent PC without having to use a seperate switch or router. I do video editing, and obviously cannot afford 10GbE in the home, so this type of setup is needed to get the 150+MB/s throughput needed for real video editing (until consumer 5GbE or 10GbE becomes available... where is that tech anyways?). I am currently using a wireless G router, and then an old (and noisy) gigabit switch (using 5 ports on a 24 port switch lol), and to be able to consolidate both devices would be really nice.

    2) High traffic performance: We all know that G and N suffer once you populate a network with a lot of devices, or have multiple networks congesting the same area. While I personally have very low traffic in my area (very low-tech neighbors), I know a ton of readers live in apartments, or have businesses with a ton of machines, and it would be nice for them to know how many devices you can have before having to worry about a serious performance fall-off. As most devices are still on N it would also be curious to see if these new routers can support more devices on N before seeing fall-off than traditional N devices.

    3) Internet performance: I have 'decently fast' internet at my home, but that is still only ~25Mb/s. But when wireless G is at 54Mb/s it makes it rather hard to justify getting anything faster than G for your average home user that is simply using wireless on 1-3 devices for internet access, and there is very little file sharing going on. Are there any real-world tests to show some significant performance boost for such simple 'internet only' uses? Perhaps lower ping rates, or more consistent performance at that 25Mb/s level?

    4) Power savings: I think more than anything that 11ac is going to show most of it's usefulness in power savings for future portable devices (and I think that ties in a lot with why they are marketing it as 5G to tie in with the cell network speak of 3G and 4G). I look at my friends phones that are only 1-2 years old, and they have to disable the wifi to get a full day's battery out of the phone because wifi's idle simply takes too much power. Compare that to new phones (or even higher quality old phones) which you can leave the wifi on all day and not have a significant battery issue. Even my 5 year old laptop gains an hour or more of battery life (a near 1/3 life boost) simply by turning off the wifi switch, so obviously the new radios in devices are getting much better at battery life without sacrificing much in the way of performance. Also cell providers like ATT and VZW have a lot of incentive to push 5G on phones and in houses to off-load cell traffic.
    Anywho, I guess what I am curious about is if the actual network speed is what gains the battery performance, or if it is merely having a more modern radio which brings such gains. As mentioned already, I am running 11g both at work and at home, and so 'all things being equal' the battery impact of wireless appears to have more to do with how modern the device is rather than the speed of the wireless network. I understand the 'race to sleep' argument, but if your internet coming in is only ~5-30Mb/s then I relay wonder if the end device will be able to sleep much at all. Because no matter if your network is 54Mb/s or 1300Mb/s the slow drip of the internet connection is going to keep those radios awake the entire time the internet is up. So is the 5G battery improvement really going to be from the network speed? Or is it merely going to be a factor of having a smaller and more efficient radio package to begin with regardless of what network it hooks up to?
    -Note: this is not the same thing as comparing 3G to 4G/LTE networks where the actual internet speed is faster allowing the device to gets it's job done faster and go to sleep faster. When on a network the internet speed is a relative constant (and almost always slower than 11g), and I am curious if changing the wireless from 11g to 11n/ac provides any battery gain on any given device for a set workload.



    Anywho, Great article! My old wireless G router is starting to have troubles, and needs to be reset every 4-6 weeks, so I am really curious about getting either a high end 11n device, or a midrange 11ac device before the year is out. And if I can find one that can last the 8+ years that my current linksys G router did then all the better! We don't see a lot of wireless articles here on Toms, and it is something that is increasingly important as people put heavier workloads and take bigger machines off of wired connections.

    I tried both the Netgear R6300 and Asus RT-AC66U in my 3 story home. I did some pretty thorough testing and the ASUS bested the Netgear overall with superior coverage and slightly better speeds in my home. Performance with both was very good, but the Asus edged by a good enough margin that I returned the Netgear. With the Rt-AC66U router on my bottom floor in my office I get amazing throughput to every corner of my house compared to my old WNDR3800. Using a Linksys WUMC710 bridge to my HTPC on the second floor I see average transfer speeds of over 30-35MB/sec. Best I could achieve with the 3800 was around 10MB/sec. Using a A6200 AC adapter on the 3rd floor I still see fantastic transfer rates of 20-25MB/sec. Wireless N on the 5Ghz band is impressive as well reaching my whole house where the WNDR3800 would barely have solid signal to my HTPC.
