Mercusys AC12G comes in a black design with 4 status LED in front. Despite being so cheap, the hardware quality is pretty decent with good build quality and materials used on the router. Mercusys also included 4 external 5dBi high gain antennas on the router.
Despite the claimed speed of up to 867Mbps, this speed is not possible due to noise and signal loss in the real world. The maximum connectivity speed for a WiFi connection is typically around 60% of the claimed link speed.
Mercusys AC12G Setup
Mercusys AC12G is really easy to setup. Just connect the WAN port to your modem. Once this is done, connect to the default WiFi name to setup the router. You can use either a phone or a computer to setup the router.
The default web interface is 192.168.1.1 with a quick setup wizard. If you use Unifi, you can refer to my setup guide here. The HyppTV should be connected to LAN 1.
Once the Internet setup is done, the wizard will guide you to setup the WiFi username and password for both 2.4Ghz and 5Ghz. I recommend using different WiFi name so you can manually select which one to connect to.
Firmware and Features
The firmware on the Mercusys AC12G is very basic without much features since this is a really basic wireless router. The main tab let you to see connected devices and change WiFi name and password.
The advanced page come with more features such as IPV6 and the advanced configurations for the WiFi connection. The router also comes with a basic parental control feature to limit the usage time limit for the devices. The NAT Boost feature should always be enabled for the best performance.
The firmware is very easy to use and navigate around. Although it does not come with an app, the interface work nicely on a phone as well. We recommend updating your firmware to the latest one from Mercusys website here.
In this test, we will see what is the maximum wired Ethernet speed the CPU of the Mercusys AC12G can handle since Mercusys advertise Gigabit ports on this router. We have no problem reaching up to 850Mbps reliably on a speedtest with no other load on the network.
WiFi Speed Testing
We will also be testing the WiFi performance of the Mercusys AC12G using a laptop with a good AC1200 WiFi Adapter. We will test the WiFi speed on speedtest.net with our 1Gbps Internet connection and see what is the fastest speed we can get. The test will be done on the 5Ghz network.
I am actually quite surprised from the result as this is better than I thought. Cheaper AC1200 routers typically perform around the 300Mbps mark but this Mercusys get to a higher 450Mbps download speed. The long distance performance is still respectable at around 180Mbps.
Mercusys AC12G is a great affordable wireless router. It will provide better WiFi speed than the router given by the ISP. The setup process is also really simple and easy. There’s even a 3 years warranty on this router. But, it is a really basic router without any additional features you may find on other more expensive routers.
At just RM1XX, it will be a perfect router if you are still using the ISP router and you are on a really tight budget.
