Setting up and using the ASUS RT-AC86U wireless router

ASUS RT-AC86U can be set up just like any other router. When you load the quick setup wizard in a web browser, you are first asked to change the default username and password, which you should. Then, the wizard detects the type of your internet connection and asks for the necessary details. Once that is done, you can set the name and password for the two wireless bands that are broadcast by the router.


When the initial setup is over, you are shown a summary of your settings, and you can then load the administration user interface. As you can see below, the interface of ASUS RT-AC86U wireless router looks the same as on all modern ASUS routers. It is very well organized, and finding your way should be easy both for knowledgeable users and for beginners. If you have a network with many devices, you will appreciate the Status tab, on the Network Map, which shows the resource consumption for the processor and the RAM, as well as the speed of each Ethernet port.


As always with ASUS routers, the help documentation is easily available. One way is to move the mouse over a setting and, when it turns into a question mark, click on it. This displays a tooltip with more information about that setting. You also get links to FAQ documentation in several sections with settings.


The user interface is available in nineteen languages, which you can see below.


When we finished configuring everything on the ASUS RT-AC86U router, we connected all the devices from our network: desktop computers, laptops, tablets, smartphones, smart plugs, smart bulbs, consoles, and a wireless printer. We had no issues when connecting any of them. Also, the wireless network broadcast by ASUS RT-AC86U was fast and stable in our whole test apartment. The only downside that we identified is the fact that you cannot mount this router on walls. Also, it can be placed only in one position.

Overall, we are pleased with this router's operation, its speed, ease of use and configuration. We had no stability issues, and the wireless network was fast everywhere in our test apartment.
