Linksys recently released the WRT1900AC router, intended to be the highest-performance AC1900 router on the market. They were nice enough to send me one to review; here is Part Two of my review where I evaluate the router on Coverage, Performance, Stability and Overall Evaluation. Part One where I detail installation is here.
Coverage
The location that I chose for my router is in the basement networking closet, in the back corner of the house. In other words, when I laid out my home network, I chose the worst possible location for a wireless router. Duh! This means that I’ve seen some coverage gaps in the house: in the home office, in my daughter’s room, and on the front and back porches. I’ve seen these issues with my otherwise-outstanding NETGEAR WNDR3700v2, with the EA6700 and with the EA6900. The R7000 provided acceptable coverage on the 2.4GHz band in these locations, and also provided acceptable 5 GHz coverage in the home office.
The WRT1900AC provided superior coverage in all locations throughout the house and on both bands. Linksys uses a higher-powered radio and a four antenna system, and it simply provides a more stable and higher-power connection on both bands everywhere in the home where I want to use wireless. In fact, I was able to get a stable 2.4 Ghz signal in my neighbor’s yard with my Microsoft Surface RT, something that no other router that I’ve reviewed has been able to do. Advantage to the WRT1900AC.
Performance
One of the main reasons to look at wireless AC is to leverage the higher speeds available, with some sources claiming double or triple the speeds available to users of wireless N routers. Of course, you need to have wireless AC gear to see higher speeds. What did I note when I ran performance testing? Let’s see. First a few notes about how I tested. I used an HP HDX Premium laptop with a NETGEAR A6200 WiFi USB Adapter; this adapter promises AC1200 speeds when connected to the 5 GHz band. I loaded jperf network testing software onto the laptop, and also onto an HP desktop with wired access to the WRT1900AC router. Note that the network strength of the location that the HP HDX was in was not optimal, leading to somewhat lower speeds than others testing in more optimal conditions; this should reflect more of a real-world performance and also will illustrate the differences between wireless N and AC speeds.
The WRT1900AC was tested in four modes: AC Only on 5 GHz, Mixed AC/N on the 5GHz band, N Only on the 5 GHz band and N Only on the 2.4 GHz band. The following graph shows the results of the jperf performance runs, with 40 tests run for each router mode.

Overall performance can be summarized as follows:

These speeds are lower than other testing that I’ve seen published on the internet, as those tests are largely conducted under more optimal connection conditions. I plan to update my testing results by testing in optimal connection conditions, but these results do clearly show that AC delivers double to triple the speeds in your implementation, and these speeds are consistent with streaming 1080i/p content wirelessly. I have seen flawless streaming of live Media Center 1080i TV broadcasts to my Surface Pro 3 using AC on the 5 GHz band, something that dual stream N routers always struggled with. I’d say that the WRT1900AC delivers on wireless performance.
On a side note, these speeds are consistent with speeds that I’ve achieved with the EA6900 from Linksys and the R7000 from NETGEAR. However, range is markedly superior on the WRT1900AC compared with these lower-priced competitors. If you are seeing dead spots using these other AC1900 products, you may see better range performance with the WRT1900AC. The above performance testing was not possible to complete with the EA6900 and R7000 in the location that I performed this testing as their radios did not have sufficient range to maintain consistent 5 GHz connections to that section of my home. The WRT1900AC has eliminated that issue for me.
Stability
Stability to me is can I set the router up and then have it perform adequately without requiring a reset. The gold standard here for comparison is my old NETGEAR WNDR3700v2 router; it ran without a reboot being required for over a year. The EA6700 seems to have had a heat control issue; it required reboots several times per week. The EA6900 was as stable as the WNDR3700v2; I can’t recall rebooting it to restore service over the 2 months that it was in production as my main router. The NETGEAR R7000, however, had major firmware issues which required reboots several times per week. Recent firmware updates helped with this, fixing issues seen on the 5 GHz band, but resets were still required several times per week to restore 2.4 GHz connectivity. In addition, printers connecting to the R700, on either the 2.4 Ghz band or the 5 GHz band, randomly disconnected, or became unreachable even though the R7000 reported them as being connected. This behavior persists for me in the current firmware being used on the R7000 today.
The WRT1900AC has been as stable as the NETGEAR WNDR3700v2 was for me. I have not had to reboot the router once in the 8 weeks that it has been running as my primary router. Advantage to the WRT1900AC.
Smart Wi-Fi Tweaks on the WRT1900AC
Linksys has enhanced Smart Wi-Fi, particularly the device network mapping feature. Here is the new Smart Wi-Fi network map for my network:

Here’s some detail for one of the devices that is connected:

I find Smart Wi-Fi to be very useful, and the device map makes it easy to see what is connected and what the IP address and MAC address is. This can be useful when troubleshooting and is a nice step up from the less complete network mapping feature available in the prior releases of Smart Wi-Fi.
In addition to network mapping, Smart Wi-Fi continues to support mobile app access to your network, as well as per-device parental controls to control certain devices on your network. I find these features to be well-designed and see Smart Wi-Fi as a useful addition to the router featureset.
Overall Evaluation
The WRTAC1900 is the best-performing router that I’ve seen yet…and I recommend it heartily as the current performance and range king in the AC1900 space. Andrew recently needed a new router and asked me if this router was worth the difference in price. I told him to buy this router without hesitation and he did; he was amazed at the performance and range that it delivers. This is my current go-to recommendation for AC1900 routers.
If you are currently in the market for an AC1900 router, and are considering the EA600 or R7000, the WRT1900AC is a step up in range, while delivering similar speed and performance. Compared to the R7000, this router has been more stable and delivered better connectivity for 2.4 GHz devices and printers. Compared with the EA6900, performance and stability is comparable, but with much better range. Pricing is about $60-$80 USD higher than these competing AC1900 routers (as per today’s pricing available online via Best Buy in the US). Is it worth the premium? If you are having range issues now in your home, then I would gladly pay the premium and buy the WRT1900AC over these competitors. If you are not seeing range issues, then you have a harder decision….but I recommend spending the extra on this router. The WRT1900AC is my current go-to recommendation for high-performance AC1900 routers and is awarded it a 5/5 Gold Award.

Special thanks to Linksys for providing the WRT1900AC router tested in these two articles. It had no impact on my evaluation, but you need to know that this router was provided free of charge for this review. And stay tuned for reviews of the accessories that will be available on the WRT1900AC!
