Linksys WRT3200ACM Dual-Band Tri-Stream 160 Router Review (Retested) – MBReviews


The Linksys WRT3200ACM is among the many two strongest wi-fi routers from the Linksys WRT collection (together with the WRT32X) and a successor to some of the well-liked AC1900 router, the WRT1900ACS. Because the identify suggests, the WRT3200ACM is an AC3200 system, however this can be deceptive for some, as a result of we aren’t coping with a tri-band router (which signifies that there’s no further 5GHz radio and the router options the standard dual-band radios), however as an alternative Linksys carried out the Tri-Stream 160 know-how, subsequently, making the WRT3200ACM the primary router to help contiguous 160 MHz bandwidth channels in 5Ghz.

I already had a take a look at one other router which additionally helps 160MHz bandwidth mode (the NETGEAR Nighthawk X4S R7800) however it’s carried out in a 80 + 80 MHz setup.
I’m glad that Linksys needs to go additional with the know-how improvement, however even in 2018, the units that do help contiguous 160 MHz bandwidth channels are very troublesome to seek out, so, this new function might be helpful solely if in case you have no less than two units of the identical variety (two Linksys WRT3200ACM or WRT32X) linked in bridge mode. Whereas the standard shopper gained’t be capable of benefit from any of the primary promoting factors of the WRT3200ACM, this router will assist enhance some networks, so let’s see if it’s value upgrading over the WRT1900ACS.

UPDATE 07.22.2018: The Linksys WRT3200ACM has gone by way of a number of radical modifications throughout its two years of existence, so, whereas at first the router would perform correctly and had a unbelievable wi-fi efficiency, typically final yr, a lot of customers began complaining that the WRT3200ACM was having critical points with the 5GHz radio (some have hinted that it might be a hardware drawback and that the Marvell chip wanted to be modified) and that the LED lights would develop into dim after a number of months of regular use. Contemplating that the evaluation I did a yr and a half in the past might not painting the present situation of the WRT3200ACM, I re-purchased it and retested the gadget to see if Linksys has managed to launch a secure firmware which might at the very least clear up the 5GHz radio instability.



A couple of years in the past, Linksys made the choice to take inspiration from the design of the long-lasting Linksys WRT54G and create a soul successor which can take the Linksys legacy additional. That’s how the WRT1900AC was born, a tool which apart from being one of many quickest AC1900 router available on the market, it used a really distinctive case design which not solely gathered the nostalgic followers, it additionally caught the eye of a brand new viewers which was exasperated by the continual launch of the similar-looking black or white consumer-focused routers.

The designers from Linksys appreciated the brand new look a lot that they determined to maintain it for all the collection, making it fairly onerous to inform the routers aside (apart from the WRT1200AC, which has two antennas and the LINKSYS WRT32X AC3200 which is simply utterly black). I do know that the design is the least necessary facet in a router, however I discover it a bit ridiculous that I can’t actually inform aside the WRT1900ACS from the WRT3200ACM (it’s been virtually two years, deliver one thing new to the desk!).


Regardless of borrowing the design of the WRT1900ACS, the WRT3200ACM seems quite a bit higher than a whole lot of different routers available on the market, the case being divided into two elements: the again aspect which is roofed by a black matte end and with plenty of holes on prime for a correct airflow and the blue entrance aspect, which is a bit shiny (however doesn’t retain fingerprints). The twin-band detachable antennas are positioned in the identical method, with two of them on the again aspect and the final two, every on one aspect of the router (since they’re fairly small and near the rear aspect, it gained’t pose any inconvenience).

The footprint of the WRT3200ACM stays the identical, with 9.68 x 7.63 x 2.04 inches and the load is a bit lighter (28.16 oz), so it falls into the pretty giant routers class (together with Asus RT-AC88U and Netgear Nighthawk R7800 X4S). By default, the WRT3200ACM might be positioned flat on a floor, however it can be wall-mounted should you lack sufficient area to maintain it correctly ventilated (each ft has particular holes to make use of for wall-mounting).


On the underside aspect of the router, there are 4 rubber ft which might be giant sufficient to maintain the gadget sturdy even in the event you join all of the ports and there are one other two sections of quite a few puncture holes that assist hold the case nicely ventilated (and the WRT3200ACM undoubtedly wants it since Linksys determined to take away the fail-safe fan on the early mannequin of WRT1900AC). Additionally on the underside, there’s a small label which accommodates numerous information concerning the system (such because the Serial Quantity, the MAC Tackle and the default SSID and password).


On the entrance of the gadget, on the black shiny plastic, there’s a collection of white LED lights (seven instantly on the entrance and 5 barely in the direction of the best), which present the standing of Energy (if it blinks, it signifies that it’s booting up or it’s in self-diagnostic mode), Web (if it’s strong amber, it signifies that the connection is down due to some configuration points and if the LED blinks an amber color, then the connection is down due to hardware issues), the two.4GHz and 5GHz band (if both of the 2 LEDs are blinking, then the router is receiving or sending knowledge), eSata, USB 1, USB 2 (there are two indicators, on prime of one another: the road and the dot signifies a USB system has been related and if the dot is turned off, then a USB system has been related), the 4 LAN Ethernet ports (each port has a main T indicator and a secondary dot indicator: if the dot is turned off, then there’s a system related at 10/100Mbps, in any other case, the connection is at 1000Mbps) and for the WPS (if the LED is strong white for five seconds, then the connection has been profitable, in any other case, if the LED blinks an amber color, then the method has failed).


Supply: FCC ID Picture

UPDATE: A fast look contained in the case has revealed that the port LEDs are huge and can perform correctly for a very long time, whereas the remainder of the LED indicators are smaller and ‘forced’ to supply the identical degree of brightness, so this can be the rationale why so many individuals have complained concerning the LEDs getting dimmer over time.

Flip the router round and you’re greeted by numerous ports and buttons: from the left, there’s an antenna connector, a WPS button, 4 Gigabit (10/100/1000) Ethernet LAN ports, an Web port, a USB port, a combo USB / eSATA port (it’s good to see that Linksys didn’t put any USB ports on the entrance or lateral sides), a small pink recessed button (press it for 10 seconds to reset the router to manufacturing unit default settings), the Energy port and one other antenna connector.


Identical to with another mannequin from the WRT collection, the WRT3200ACM does not likely have a chic design and it might not really feel at house in a living-room with basic furnishings, however, the case is just not ugly by any means and it’ll slot in on a desk together with a contemporary desktop PC.
Observe: Contained in the package deal, you will discover the Linksys WRT3200ACM unit, a Fast Begin Information, a CD with documentation, an Ethernet cable, the Energy adapter and the 4 antennas.

On the within, the Linksys WRT3200ACM is provided with a dual-core 1.8GHz Marvel Armada 88F6820 ARMv7, Marvell 88E6352 change, 512 MB of RAM (Micron DDR3) and 256 MB of flash reminiscence (Spansion NAND). Moreover, the two.4GHz radio band makes use of the Marvell 88W8964 chipset, together with a Skyworks SKY85309-11 2.4GHz front-end module and the 5GHz radio band additionally makes use of the Marvell 88W8964 chipset, together with the Skyworks SKY85728-11 5 GHz front-end module.


The Linksys WRT3200ACM contains a most theoretical knowledge switch price of 600 Mbps utilizing the two.4GHz radio band and the utmost theoretical knowledge switch price of 2600 Mbps utilizing the 5GHz radio band (added to the marketed 3200 Mbps).
Word: The facility consumption, whereas operational, is roughly 33 Watts.

Options and Efficiency
The Linksys WRT3200ACM is a three×three AC3200 class router, however, as stated within the introduction, we aren’t coping with a tri-band router and one of many most important indicators is as a result of it makes use of the MU-MIMO know-how (as anticipated the AC3200 line is usually utilized by routers that function the Broadcom’s XStream Tri-band know-how, such because the TP-Hyperlink AC3200, D-Hyperlink DIR-890L and Asus AC3200).


The standard tri-band router options a further 5GHz radio band, apart from the widespread dual-band setup and it helps lots with the community stability by balancing the load between the three radios, subsequently growing the throughput (not the hyperlink price!). Which means a tri-band AC3200 router will work as an AC1900 one, however will have the ability to deal with much more wi-fi related shoppers and guarantee a greater community stability.

The Marvell’s MU-MIMO know-how is a completely totally different beast and the best way it really works is that as an alternative of serving one shopper at a time (the standard SU-MIMO strategy), a number of customers could be served concurrently. Because of this each related MU-MIMO shopper receives a person knowledge stream (thus eradicating any competitiveness for the bandwidth), permitting customers to play on-line video games or carry out any video streaming on the similar time, with out experiencing any latency. This know-how sounds unbelievable and vital in each house-hold, the one drawback is that the market hasn’t actually caught up with the speed of the networking know-how improvement (there are nonetheless plenty of individuals and corporations that contemplate the 802.11ac normal as one thing unique – this assertion stay true even in 2018).


So, the MU-MIMO know-how isn’t an answer for the current and extra probably for a potential future the place MU-MIMO suitable wi-fi playing cards are one thing typical and wide-spread.
The primary promoting level and the rationale why Linksys WRT3200ACM has been developed is the Tri-Stream 160 function. To get a greater understanding about how this tech works, let’s take the standard three-stream AC1900 router (three×three), with every stream maxing out at 433 Mbps utilizing the 80MHz bandwidth mode (subsequently going to the utmost marketed price of 1,300 Mbps for the 5GHz radio band). The Tri-Stream 160 know-how makes use of just about the identical idea, however as an alternative of utilizing the 80MHz bandwidth mode, you get three streams at 160Mhz channel width, subsequently driving knowledge at 867Mbps on every stream (including as much as the marketed 2,600 Mbps on the 5GHz radio band).

The Tri-Stream 160 positive seems like a game-changer, however can the standard consumer truly use it with any of the at present current units? Umm, no. The one system that helps this tech is one other WRT3200ACM router (inner knowledge streams shall be unbelievable utilizing the bridge mode, no doubt) and, since there are not any different suitable wi-fi adapter available on the market (and for those who use 1×1 or 2×2 wi-fi adapters), the WRT3200ACM will carry out equally to a better finish AC1900 router and nothing extra. This can be a sin that the majority router producers are responsible of, inflating the field quantity as a lot as they will, whereas the standard individual can be hypnotized into considering that they’ll get the hyperlink charges from the field.


That being stated, the WRT3200ACM is certainly future-proof, however I’m not likely positive that that is the way forward for the networking world (Linksys thinks so and it has ready approach forward of time) and my opinion is that a tri-band router (whereas undoubtedly not being superior), has the benefit of not needing any particular suitable wi-fi adapters, simply ones which use the 5GHz radio band (moreover, the tri-band strategy has labored out nice for the WiFi mesh techniques (such because the Orbi, Eero 2nd Gen or the Velop) that wanted a dependable approach of dealing with the backhaul visitors). The final function that I need to point out from the Linksys WRT3200ACM is the Beamforming know-how which has the position of optimizing the community efficiency by scanning the world, figuring out the related units (wi-fi) and focusing the sign instantly at them, as an alternative of broadcasting it in all places, hoping it’ll attain the related shoppers.


To be able to check the wi-fi efficiency of the Linksys WRT3200ACM, I took a laptop computer with a suitable wi-fi adapter and a desktop PC (additionally with a built-in suitable wi-fi adapter outfitted with one of the crucial highly effective wi-fi adapter on the buyer market, the Asus PCE-AC88) and I measured the velocity efficiency at totally different places inside a big home (whereas maintaining the interferences to a minimal).
UPDATE: I’ve stored the preliminary check outcomes to showcase the enhancements that Linksys has made through the years and the brand new checks have been completed after three days from the buying date and the router has been stored operating constantly throughout this era to be able to see when (and if) I’ll expertise the identical issues with the 5GHz radio band – the WRT3200ACM has been up to date to the newest firmware, the

So, utilizing the two.4GHz radio band (and implicitly, the 802.11n commonplace – 20MHz bandwidth mode), at shut vary (5 ft), I measured a mean of 217 Mbps 151 Mbps (it peaked at 156 Mbps). Afterwards, at 15 ft, the velocity decreased to 144Mbps truly went as much as 219 Mbps and at 35 ft, I measured a mean of 95 Mbps 70 Mbps.


Since I obtained an general higher wi-fi velocity efficiency on the two.4GHz band, I switched to the 5GHz radio band (utilizing the 802.11ac commonplace and the 80MHz bandwidth mode) and utilizing the PCE-AC88, I acquired the next outcomes: 5 ft away from the router, I managed to measure a mean of 812 Mbps (with the height at 936 Mbps), whereas at 15 ft, the velocity went right down to 647 Mbps and lastly, at 30 ft, I measured a mean of 537 Mbps.

Clearly, until you employ one of the best WiFi adapters available on the market, you gained’t see this kind of efficiency, so utilizing a pc with a extra widespread adapter, I obtained the next outcomes: at shut vary (not more than 5 ft), I managed to measure a mean of 563 Mbps a most of 557 Mbps (it averaged at round 548 Mbps), whereas at 15 ft, the velocity decreased to 525 Mbps 484 Mbps. Lastly, at 35 ft, I measured a mean of 334 Mbps 322 Mbps. As you’ll be able to see, the velocity efficiency on the 5GHz radio has remained just about constant to what I measured the primary time I examined the WRt3200ACM, whereas utilizing a extra highly effective adapter has delivered a big efficiency enchancment particularly close to the router (the place I received near 1Gbps).

As a result of the router has a USB port, I needed to measure the storage efficiency and see the way it stands towards its predecessor, the WRT1900ACS. So, I took a GB folder containing multimedia information (movies, music and books) and I measured a writing velocity of 88.5MBps and a studying velocity of 113.1MBps. This makes it one of many quickest router from the storage viewpoint out there available on the market proper now.

Setup and Interface

The setup strategy of the WRT3200ACM is so simple as with some other trendy wi-fi router: join your PC to the wi-fi identify and use the password proven on the label (from the underside of the gadget) and open an internet browser to launch the Linksys Sensible Router Setup (if the wizard doesn’t launch instantaneously, go to The setup wizard will information you thru configuring the Wi-fi Settings (the SSIDs and the password for each radio bands), create a brand new router password (together with a touch) and create a Linksys Sensible WiFi Account (which lets you entry your community remotely). By default, the connection sort settings are completed routinely, however you may as well get the choice to carry out the guide configuration. After ending the preliminary setup, you achieve entry to the UI to configure your router at a extra in-depth degree.


UPDATE: The second time I configured the WRT3200ACM, I used the Linksys cellular app (the identical that’s used to configure each the tri-band and the dual-band Velop methods) and the steps have been just about the identical as on the browser-based interface: choosing ‘A Linksys Router’ as an alternative of ‘A Velop System’, connecting to the router’s WiFi community and ready till the system will get detected by the app, putting in the newest firmware replace, establishing the 2 WiFi networks and that’s just about it – from right here on, you’ll be capable of freely roam the cellular and the browser-based interfaces.

The primary web page of the browser interface has a menu on the left with all of the necessary sections with choices, every displaying a brand new window within the centre. On the proper aspect, you get 9 small home windows which present the Standing of the Community, the Linksys Residence Networking shortcut, the WiFi Settings, the Visitor Entry, the standing of the Parental Controls, the Exterior Storage, the Media Prioritization standing and the Community Map. The primary part is the Sensible WiFi Instruments and has the next choices: Community Map (a graphical illustration of your community, together with the Visitor Community and the Web Utilization), Visitor Entry (permits you to create visitor community names with passwords and you may select the utmost variety of visitors allowed), Parental Controls (you possibly can prohibit entry to particular units, block the Web entry throughout particular occasions or all the time and block particular web sites), Media Prioritization (drag and drop units within the regular or excessive precedence part and select the Purposes together with the On-line Video games for these sections), Velocity Examine and Exterior Storage (Standing, Folder Entry, FTP Server and Media Server).


Instantly beneath the Sensible WiFi Instruments, you’ll be able to see the Router Settings: Connectivity (the Primary settings – Community Identify and Password, Router Password, Firmware Replace, Time Zone and Exercise Lights; Web Settings – IPv4 or IPv6 Connection Sort, MAC Handle Clone and MTU; Native Community – Router Particulars and DHCP Server; Superior Routing – NAT, Dynamic Routing and Static Routing; VLAN – VLAN, Web(Trunk) and Ethernet; Administration: Native Administration Entry, UPnP and Software Layer Gateway), Troubleshooting (Standing, Diagnostics and Logs), WiFi Settings (Wi-fi settings, MAC Filtering, WiFi Protected Setup and Wi-fi Scheduler), Safety (Firewall – Firewall, VPN Passthrough, Web filters and IPv6 Port Providers; DMZ; Apps and Gaming – DDNS, Single Port Forwarding, Port Vary Forwarding and port Vary Triggering) and OpenVPN Server. Whereas the app was fast and intuitive, I observed that the web-based interface was sluggish and I had some hassle discovering some choices (resembling one thing so simple as discovering the place to improve the firmware – as a touch, it’s underneath Connectivity).


In addition to the MU-MIMO and the Tri-Stream 160 function, the third essential promoting level of the Linksys WRT3200ACM is the help for Open Supply firmwares. Because the router is made with this sort of compatibility, the OpenWRT or DD-WRT customized firmwares shall be extra secure than on the opposite routers, however there’s one thing I didn’t fairly perceive. Whereas the WRT3200ACM is marketed as being Open-Supply Prepared, on their web site it’s written: “Installing 3rd party firmware is done at your own risk and replacing factory-installed firmware with open source firmware will void your warranty.” So, whereas Linksys encourages you to go for third social gathering firmwares, it won’t repair the product if one thing goes mistaken.

UPDATE: The help for open-source firmware has been one cause why so many individuals determined to go together with routers from the WRT collection, however, in contrast to different producers which were usually properly regarded by third-part builders (corresponding to Asuswrt-Merlin for Asus routers), Linksys critically lacks on this division. At this second, I might not advocate utilizing DDWRT with the WRT3200ACM (it brings virtually nothing new when it comes to options and it feels dated), however I did discover plenty of constructive suggestions from the LEDE venture staff, so, if you wish to use a third-party firmware, I might go for OpenWRT.

I’m not likely positive what to consider the Linksys WRT3200ACM as a result of for me, it’s a combined bag. On one hand, you get an above common wi-fi efficiency, a implausible storage efficiency and a simple-to-use app interface (whereas the browser-based interface could be very sluggish). However, then again, all of those new options lack any usability in the actual world and the one individuals to benefit from them can be people who truly buy two of those models and use them in bridge mode. Moreover, the help for customized firmwares had the potential to make this router one of many quickest available on the market, however thus far it didn’t occur. General, in its present situation (and 4 days since I’ve it), the WRT3200ACM is performing rather well, so I’ll maintain it for some time longer to see if Linksys managed to repair all the points and has made the WRT collection nice once more.
