How to connect to the router Xiaomi AX1800: the complete guide

Installing a modern router often seems like a daunting task requiring a deep knowledge of networking technologies, but with Xiaomi products, the process is as simple as possible. The AX1800 is a powerful device that supports the Wi-Fi 6 standard, which provides high data transfer speeds even when you connect many gadgets at once. Proper initial configuration is critical for the stable operation of the entire home network in the future.

In this guide, we’ll take you through everything from physical cables to fine-tuning security and guest access. You’ll learn how to avoid the typical mistakes users experience when they first activate a device. The router’s management interface is intuitive, but language barriers or specific features may raise questions for beginners.

Before starting the procedure, make sure you have access to an Internet cable from the provider and a charged smartphone or laptop with a Wi-Fi module. It is also recommended to know the details for authorization in the provider’s network in advance if you use the type of connection PPPoE or L2TP. The factory administrator password is absent, you set it yourself when you first log in.

Preparation of equipment and physical connection

The first step is to switch devices correctly. The Xiaomi AX1800 router is equipped with automatic connection type (WAN/LAN) ports, which simplifies the process, but for reliability it is better to follow the standard scheme.

The power supply of the device must be stable, so only use the original power supply from the supply kit. If you plan to use a wired connection to set up, connect your computer to any free LAN port using an Ethernet cable. Wireless connectivity is also possible immediately after switching on, but it is less stable in the initial configuration.

  • 🔌 Connect the provider cable to the port WAN (usually blue on the back panel.
  • ⚡ Use the original power adapter 12V/1A avoiding reloading under load.
  • 📡 Wait until the system indicator lights up in orange or white, signaling readiness.
  • 💻 For initial setup, it is preferable to use an Ethernet cable to avoid communication interruptions.

⚠️ Note: Do not connect the provider’s cable to a port marked as IPTV, If your provider does not require a specific configuration of this port, otherwise the Internet will not work.

After the power is applied, the router takes about 60 seconds to fully load the operating system, at which time the indicator flashes, and the device conducts self-diagnosis. If the indicator is lit red or flashes red, this may indicate a lack of signal from the provider or damage to the cable.

Web interface login and primary authorization

To access the settings, you need to go to the local address of the device. Open any browser on the connected gadget and type in the address bar IP-192.168.31.1 or the domain name miwifi.com. If the page doesn't load, make sure your device is actually connected to the router's network and receives the IP-address automatically DHCP.

When you first log in, the system will suggest you choose the interface language. Although Russian localization is present in global versions of the firmware, sometimes you may need a translator for some specific menu items. Once you select the language, you will begin a quick setup process that will take no more than two minutes.

The key is to create an administrator password.The management password will be used to log into settings in the future, so write it down to a secure location.The Xiaomi security system requires the password to contain letters and numbers, which is good practice for protecting against unauthorized access.

Configuring an Internet connection (WAN)

The next step is to set up the type of connection to the WAN. The AX1800 router automatically determines the type of connection used by the provider, but in some cases requires manual selection of parameters. Most modern providers use Dynamic IP (DHCP) when settings are not required at all.

If your provider uses a link to MAC-address, which is often found in old subscribers, the router will offer to clone MAC-This can be done automatically in the configuration interface. For PPPoE users (for example, Rostelecom, Dom.ru), you need to enter a login and password from the contract.

Type of connectionRequired dataFrequency of use
Dynamic IP (DHCP)Not requiredHigh (about 70%)
PPPoELogin and passwordMedium (large providers)
Static IPIP, Mask, Gateway, DNSLow (business rates)
L2TP/PPTPServer, login, passwordLow (obsolete)

In the case of static use IP-Addresses, data must be entered manually, observing the register and format. Error even in one digit of the subnet mask will lead to no access to the network. After entering all the parameters, click the "Apply" or "Save" button and the router will try to establish a connection.

Configuration of Wi-Fi wireless network

Configuring a wireless network is one of the most important steps in influencing signal speed and coverage. The AX1800 supports dual-band operation (2.4 GHz and 5 GHz), which you can combine into a single smart-switch network or divide into two separate access points with different names.

The 5GHz band is recommended to choose the channels with the lowest congestion, although the router is able to do this automatically.The Wi-Fi 6 standard (802.11ax) provides a significant increase in speed compared to previous generations, but to use it, the receiving device must also support this standard.

In the security settings, be sure to select the type of encryption WPA2/WPA3 This will ensure maximum protection of your data from interception. The password phrase should be quite complex, contain at least 8 symbols, including numbers and special signs.

Do you want to use the dual band integration function?
Enabling this feature combines 2.4 GHz and 5 GHz networks under one name. The router decides what frequency to connect the device. It's convenient for users, but sometimes old gadgets can mistakenly connect to an slower 2.4 GHz even in the range of 5 GHz. If you have a lot of smart homes, it's better to split the networks.

Be sure to change the network name (SSID) to unique to easily identify your access point in an apartment building. avoid using special symbols in the network name, as some older devices may not display them correctly or refuse to connect.

Managing the device through a mobile application

To help you monitor your network, Xiaomi has developed Mi Wi-Fi (or Xiaomi Home depending on the region) from the official app store and log in via your Mi Account.

The app can quickly check who is connected to your network and block uninvited guests if necessary, and it also offers Guest Wi-Fi, which creates an isolated network for visitors without giving them access to your personal files on the NAS or printers.

  • 📱 Remote management of settings via the Internet from anywhere in the world.
  • 🚫 Blocking Unknown Devices in One Click Through Customer List.
  • ⏱️ Adjusting parental controls with limited access time for children.
  • 🔄 Automatic check and installation of firmware updates.

⚠️ Note: When managing remotely, make sure that the router itself has the Remote Management feature enabled in the web interface and a strong password for the administrator account is installed.

Network diagnostics is also available in the app, which helps to identify problems with signal or congestion of channels. The coverage visualization helps to optimally place the router in the apartment for maximum coverage of the area.

Update firmware and reset settings

Regular software updates are key to the security and stability of the Xiaomi AX1800. Manufacturers often release patches that close vulnerabilities and improve compatibility with new devices. You can check for updates in the “Status” or “System settings” section.

The update process takes a few minutes, and the Internet will be unavailable at that time. The router will automatically download the packet, check its integrity and install it, then restart it.

💡

Before updating the firmware through the web interface, it is recommended to save the current configuration (backup file) in order to quickly restore all settings in the event of a reset.

If the router is not working correctly or you forgot the administrator password, reset to factory settings will help. To do this, on the enabled device, you need to press the Reset button on the back for 5-10 seconds before changing the color of the indicator, after which the device will return to the state “out of the box”.

💡

Resetting settings via the Reset button deletes all user data, including Wi-Fi passwords and provider settings, returning the router to factory status.
