This article will help you figure out where to start. We will look at how to connect to the router, perform basic Internet and Wi-Fi network settings, and also touch on the issue of firmware updates. It's not as difficult as it might seem at first glance, and you can do everything yourself.

If you haven't updated your router's software in a while or are experiencing performance issues, the next step is to install new firmware. This can improve connection stability and close potential vulnerabilities. We'll walk you through the process step by step so you can do it safely and without errors.

Almost anyone can configure and flash the Mercusys MW325R router, even without experience — just connect it to the network, go to the configuration interface via a browser, and set the necessary parameters: network name, password, and encryption type. If you are not satisfied with the standard firmware, you can install an alternative one, such as OpenWRT, to get more features, but you need to do this carefully, following the instructions, so as not to turn the router into a “brick.” The main thing is not to rush, check everything, and don't skip any steps.

Description, main features

The Mercusys brand is famous for its inexpensive routers, and the MW325R occupies a worthy place in this line. This device can be called the older brother of the MW301R, with several important advantages over one of the cheapest models on the market.

First, instead of two non-removable external antennas, there are 4 here, each with a power of 5 dBi, which guarantees a router coverage area of about 500 m2. Secondly, the number of LAN ports here has been increased to three (the junior model has two).

A review of the Mercusys MW325R router would be incomplete without listing its obvious shortcomings, among which is the ability to operate in a single band, i.e., the lack of support for the 802.11ac wireless transmission protocol. This is quite important for congested networks, as it significantly reduces the overall performance of the device. The lack of a USB port can also be considered a disadvantage, but it is hardly critical—using a router to connect a print server, for example, is not a common occurrence.

Standard package includes: router, network cable with power supply, patch cord, and documentation. The buttons and ports include three LAN ports, one WAN port, a power supply socket, and a Reset button. There is no WPS button, let alone a separate button to disable the wireless network. The antennas rotate in two planes, i.e., they are quite mobile and can be directed to cover any part of the room.

How to connect the Mercusys MW325R router to the internet

Geekbuying WWGeekbuying WW

First, you need to ensure that the router has physical access to the network. To do this, plug the cable from your ISP into the WAN port. If you have a computer with a network card, connect it to the router using the patch cord included in the package.


The device settings are configured via a web interface. To access it, enter mwlogin.net or 192.168.1.1 in the address bar of any browser – this information is indicated on the router label.

If this is the first time you are turning on the device, the Mercusys MW325R basic setup script will start, and a window will open asking you to set a password to log into the admin panel, which you can change at any time. The password must be entered twice to ensure that you did not make a mistake the first time. If you ignore the password entry, access to the web interface will be unprotected, which means that your neighbors will be able to freely use your router to access the World Wide Web.


If you forget or lose your password, you will need to reset the router to factory settings and then repeat the setup procedure.

After entering the password, click the arrow to go to the Internet access settings page. On the “Network” page, select the correct connection type. What you need to enter in this field depends on your provider—it can be a connection using PPPoE (Rostelecom), L2TP/PPTP (Beeline), dynamic or static IP protocols.

The first three connection types require authentication with data from your ISP (login/password pair). L2TP/PPTP protocols also require you to specify your ISP's VPN server address. The easiest way to connect is via a dynamic IP address. In this case, you don't need to enter anything, and protection against hacking is provided at the hardware level by registering your device's unique MAC address in your ISP's database.


When choosing a static IP, you need to specify this address, as well as the subnet mask (usually 255.255.255.0) and the addresses of the DNS servers, primary and alternative (if the first one is unavailable).

At this point, the connection of the MW325R router to the Internet can be considered complete.

How to configure the Mercusys MW325R router to distribute Wi-Fi

After connecting to the Internet, you will be prompted to enter the name of the wireless network and specify its password. Wi-Fi settings can be changed later in the “Wireless Mode” tab.

Note that the SSID parameter is the name that appears on your smartphone when searching for wireless networks. It is advisable to set a sufficiently complex password so that it cannot be hacked. After clicking the arrow, you can try connecting to the newly configured wireless network of the Mercysis router on your mobile devices and set-top boxes.

Rebooting, resetting to factory settings

To restart the router, you need to disconnect it from the network for a few seconds, as there is no power button on it. However, there is a Reset button. Press and hold it for 5-8 seconds until all the indicator lights on the panel light up to reset the router to factory settings.

However, both operations can also be performed from the admin panel by going to the “System Tools” tab.

Please note that a reboot may be necessary if the router starts to malfunction, and a reset is required if you have forgotten/lost your password for logging into the web interface.

As you can see, setting up and updating the Mercusys MW325R firmware is not that difficult. If you follow the instructions step by step, you can easily do it yourself without calling a technician.

The most important thing is to remember the basic safety rules. Always change the default Wi-Fi password to something strong and unique. And if you decide to update the firmware, only download it from the official Mercusys website to avoid any issues.

As a result, a couple of simple steps will help you make your router's performance more stable and secure. You will be confident that your network is set up correctly and that all devices are connected to a reliable Internet connection.
