ASUS RT-AC86U AC2900 Dual Band Gaming Wireless Router – Good News for Gamers! | Review

No comments


In general, ASUS AC86 is an upgraded version of its smaller brother, ASUS AC68U. Maybe you can reverse the “68 to 86 or vice versa” for extra understandings. This router, has the similar design of Lamborghini sports cars along with my beloved, ASUS G752VT laptop. I personally like the design compared to its traditional looking small bro, AC68U. Despite for its price, this router suitable for gamers out there due to the built-in WTF feature, a dual core 1.8GHz processor, along with the beast alike 512MiB to handle the connected devices well.


Disclaimer: This is a Malaysian demo unit. So the actual packaging will be much more “cool” compared to this.

Final view of the router

This is a demo unit. So it may differ from the actual unit that comes with the router. The content that comes along with the router are, the AC adapter, three detachable antennas, a cat5e Ethernet cable, a manual and a warranty card.

The built quality of the router is excellent. The high quality casings were used, the fierce look of the front view of the router adds the impression to gamers out there, that, this is the savior of their smooth gaming experience over their existing router. The design of AC86U more like a Lamborghini’s rear view compared to the traditional diamond shape pattern of most of the ASUS routers.

The quality of the antenna’s is beyond perfect. Don’t mistaken me as, for such pricey router, the antenna’s also plays an important role to transmit the wireless coverage to your home device. When I tried to change the direction of the antennas, I feel that, it’s pretty solid compared to other previous router’s, I tested so far.

The rear view of the router is similar to its smaller brother, AC68U. The router comes with a single gigabit WAN port, 4 gigabit LAN port, a single USB 2.0 & 3.0 ports, an AC in port, a reset button, an LED on/off button and on/off button.


The specifications of the AC86U are as follows:

The process of setting up the router for first use is slightly similar to Blue-Cave, with the dark version of the user interface.

I personally like this setup interface, as it shows how premium the router is. This gives the impression of “rough” of the router not only in terms of the outer design, as well as the firmware design.


The interface of the web administration is similar to most of the ASUS routers. The attached image below is the a brief walk-through of the router.


My standard wireless settings of both bands are as follows:

Wireless Analysis

Analysis of Download:

The download speed was awesome at upstairs. I able to achieve over 90% of subscribed bandwidth, however, as the distance were increased, the speed bandwidth seems to get fluctuated.

Figure 28: The result of upload speedtest.

Analysis of Upload:

As for upload result, the same principle was applied. However, I have to redo the wireless test at the Veranda (upstairs) as my phone tends to lose the 5GHz connection (not stable).

Analysis of the wireless for both, download and upload:

The more increase the distance is, the lesser bandwidth your device will receive.

I able to achieve over 90 Mbit/s on my laptop. Sweet.


The router does come with two USB ports, each USB 2.0 and USB 3.0 respectively. In order to ease the comparison chart, I’ve renamed the path (folder) to the respective ports, they’re (USB sticks) currently connected to.

USB 3.0

Outcome of the analysis

The write speed (from my download folder to the USB stick attached) of USB 2.0 hovers around 7 – 9 MB/s while the write speed of 3.0 hovers around 10 – 11.5 MB/s.

ASUS RT-AC86U are one of the best wireless router ever produced by ASUS currently. The wireless coverage from this router are excellent, the USB read and write speed are good, and, the router seems to handle more than 10 connected devices with ease more devices can be handled well. The feature that comes with this router is great, however, I didn’t try the router with Asus-Merlin firmware as, for most home users, the stock Asuswrt is more than enough. The AiProtection scores well here. Definitely, if in the future, I am planning to get a new router for my house, definitely, Asus AC86U will be in my top list of router replacement.

My Recommendations: 9.5 / 10
