ASUS RT-AC67U Mesh WiFi System Review: AC1900 AiMesh

ASUS AiMesh is the most feature rich and flexible mesh WiFi system in the market today. ASUS RT-AC67U is an AC1900 mesh WiFI system unlike more mesh WiFi system you have seen in the market. It is developed to cover your entire home with strong WiFi coverage and fast WiFi speed.

What is Mesh WiFi?

Mesh WiFI is not that complicated to begin with. It works by having multiple mesh nodes working together to blanket your home with WiFi coverage. With better WiFi signal, it will result in a faster WiFi speed. All the mesh nodes and connected to each and other wirelessly without the need of a physical wire.

The great thing with mesh WiFi is there’s only one WiFi name to connect to unlike using WiFi repeaters. You no need to keep switching WiFi network as a mesh WiFi system uses the same WiFi name for the entire network. ASUS AiMesh system also supports roaming where it will steer your devices to the most suitable access point.

ASUS AiMesh is different as it is developed on an already strong ASUSWRT firmware that’s running on all ASUS routers. It will support more features and offer far more flexibility that other mesh WiFi system cannot offers. ASUS lets you to customize your network the way you want it without sacrificing on features. 

Hardware and Specs

  • Broadcom 1Ghz Chipset
    • 128MB Flash and 256MB RAM
  • Wireless AC1900
    • 2.4Ghz 3×3 up to 600Mbps
    • 5Ghz 3×3 up to 1300Mbps
  • 4 x Gigabit Ethernet LAN
  • 2 x USB ports

ASUS RT-AC67U comes with 2 AiMesh router in the pack to setup it as a mesh WiFi system. Both routers are exactly identical and you can use either one as the main router. Each router also comes with 3 external antennas for a better signal quality which most mesh WiFi system do not have.

Unlike  most mesh WiFi system in the market, ASUS RT-AC67U also comes with plenty of ports. Each router features 4 Gigabit Ethernet port and 2 USB ports with one of them being USB 3.0 capable. You can use the USB port to share files, printer and even use it for your private cloud storage with ASUS AiCloud.

AiMesh Setup

ASUS AiMesh setup process is slightly longer compared to the normal ASUS routers. We prefer to setup ASUS AiMesh system using the web interface as it is easier. The first unit of the RT-AC67U is connected to our ISP modem then we followed the setup wizard like any ASUS Router.  ASUS RT-AC67U AiMesh system is fully compatible with Unifi with HyppTV working. You can refer to my ASUS router Unifi setup guide here.

Once that is done, we turn on the second unit then we navigate to the web interface of the main router. We clicked the search button to search for AiMesh node. Once the second unit is found, we add it to form a Mesh WiFi network. The second router will then reboot and this entire process took us 15 minutes.

If the second router is successfully added, the router will appear in the AiMesh section. With the mesh system configured, the mesh node will have the exact same WiFi name and password as the main router. It can then be placed anywhere in your home then they will work together to improve the WiFi coverage and speed. AiMesh can also work with Ethernet backhaul.

WiFi Performance

Our key focus on the RT-AC67U will be the mesh performance and see how well it performs. Being a dual-band AC1900 router, the maximum link speed on 5Ghz is up to 1300Mbps. We will be conducting a WiFi speed test on our iPhone via Ookla’s Speedtest app around our apartment.

The performance of the RT-AC67U is really impressive. Previously, the WiFi speed at point D is barely usable due to multiple walls in between and the use of metal door in my apartment. By having the RT-AC67U mesh WiFi system, it effectively improve the WiFi speed and coverage in my entire apartment. The AiMesh node will help due to my rectangular shape layout. There is only so much a WiFi router can transmit due to regulation. 

Our setup uses the same name for both the 5Ghz and 2.4Ghz channel. We allow our device to select which band is most suitable.

Firmware and Features

ASUSWRT is without a doubt the best router firmware in the market with plenty of features and good stability. The RT-AC67U user interface is easy to use and simple to setup. ASUSWRT itself can be a really good reason to get Asus AiMesh system. RT-AC67U comes with so much features that it is impossible to say every single one of them. We selected a few where we want to focus below.

Asus Router App

Asus RT-AC67U also features the ASUS Router app. The app is pretty powerful as it very effective in monitoring the connection. You can see the health of each AiMesh node and see what devices is connected to which node. All the QoS and parental control options can be managed on the app as well.

AiProtection Pro

The RT-AC67U is not all about WiFi, it included a built-in AiProtection Antivirus solution to protect all your devices connected to the network. AiProtection is powered by TrendMicro so the database is pretty reliable. We tested it with some malware infected website and it is successfully blocked by the router.  

AiProtection is not purely an Antivirus solution. It also comes with a rather comprehensive parental control to protect your loved ones. The parental control can have a really granular content limitation base on category and the ability to configure time limits.


ASUS AdaptiveQoS is also the most robust QoS solution in the market. Not only it is the most effective application based QoS, it also offers a ton of visibility. With app analysis turned on, you can see what sort of contents the devices are using. Besides, Asus also included the Traffic Analyzer which is a log on how much traffic and categorize them. There is also a Web History feature as well. All of these can be turned off if you prefer privacy.

Closing Thoughts

ASUS AiMesh is a great system, it offers a lot of flexibility. The RT-AC67U we tested is a great mesh WiFi system with good performance. AiMesh differentiates itself from the competitors by offering a lot of features and a lot more hardware. You get a more complete package as the RT-AC67U is a fully fledged router with 4 LAN ports and a firmware that comes with plenty of features.

However, like everything, the RT-AC67U is not perfect. It lacks the 802.11k/v/r fast roaming standard. But, Asus included their own roaming mechanism and it does seem to work pretty well. We would prefer if it comes with the standardized fast roaming instead.

Hi Alyn,

For 5000sqft with 3 stories house does this ASUS RT AC67U is more sufficient enough or could u suggest me a model.

Thank you,


Point A – 556Mb – its showing for you – I am guessing its by main router, right? What is actual speed of your provider?
I tested at my house – I have 250Mb from ISP, with aimesh I am getting less that half of that in any room, is it normal?
Can you confirm if aimesh cut so much speed ?

Thank you

Hi there Alvyn,

It says it is possible to use older asus router as Aimesh node.
I have a AC1300uhp, but couldnt find it in the list of models that support Aimesh in Asus website, so i assume it’s not possible?
It’s for a 3 stories house with LAN wired throughout, any suggestion for models and/or set up?

Unifi Turbo 500m
Asus AC1300uhp as main router (Ground flr),
Huawei as second router at 1st floor (ethernet connected to main router).
Access to wifi printer at ground flr

Hi Alvyn, how is this compared to the Deco M9 from TPLink?

Would love your thoughts, please comment.x
