How to set up PPPoE on Xiaomi router

Modern routers from Xiaomi are famous for their minimalist design and intuitive interface, which greatly simplifies the process of their initial configuration. However, despite the simplicity of mobile applications, many users face difficulties when you need to configure specific connection protocols, such as PPPoE. This protocol is still actively used by providers for authorization of subscribers and traffic accounting, requiring username and password input directly on the routing device.

Properly setting PPPoE is critical, as it provides access to your local network to the global Internet. Errors at this stage lead to a lack of communication even with physically fit equipment and paid services. In this article, we will discuss all the details of the settings so that you can activate the Internet yourself without calling the wizard.

It’s worth noting that the firmware interface may vary slightly depending on the device model (e.g. Xiaomi Router 4A or Redmi AX6) and the software version. However, the logic of actions and menu structure remain the same across the ecosystem.

Preparation for setting up and data verification

Before you start typing your settings into the router's web interface, you need to make sure that you have all the technical documentation you need. Usually, the contract with the provider contains a separate insert or a section with connection parameters, which indicates the username, password and connection type. Without this data, you can not further set up, so find a contract or check the personal account of the operator.

It is also important to ensure a stable connection between your computer or smartphone and the router itself. LAN-If you don't have the ability to do that, make sure you're connected to the router's Wi-Fi network, even if you don't have the Internet yet.

⚠️ Note: If you are setting up a router that was previously used, it is highly recommended to reset to factory settings. To do this, press the Reset button on the back panel on the 10-15 It's just a second before the light flashes, so it's not going to conflict with old profiles.

Check the physical integrity of the cables: WAN-The cable from the provider must be tightly inserted into the router's blue port, and the port indicators must burn or blink, signaling the presence of a link.

Log in to the web interface of the Xiaomi router

To get started, you need to go to the device control panel. Open any modern browser (Chrome, Firefox, Safari) on the device connected to the router. IP-address 192.168.31.1 or domain name miwifi.com and click Enter.

The system will ask for an administrator password. It can be the default Wi-Fi password if you've just set up a router, or it can be set by you before. If you forget your password, you'll have to use the Reset button on the device body, and when you've successfully logged in, the main status page will open.

The interface can be in Chinese or English, depending on the firmware version (CN or Global). For convenience, it is recommended to immediately switch the language in the Settings → Status → Language section, if such an option is available in your version of the software.

Selection of connection type and protocol

Once logged in, the router often offers to run the Quick Setup Wizard. If that doesn't happen automatically, find the Internet Settings or Common Settings section at the top of the menu, and that's where the Connection Type key parameter is.

The default routers are often set to Dynamic IP (DHCP), which is the most common reason for the lack of Internet access for users whose ISPs require authorization. Choosing the right protocol causes the router to initiate the process of connecting to the ISP's server.

• 🌐 Dynamic IP: Address is issued automatically, no login is required (not suitable for PPPoE).
• 🔑 PPPoE: login and password required to log in.
• 📟 Static IP: manually IP, masks and gateways (rarely for the home).
• 📡 PPTP/L2TP: Outdated tunneling protocols (practically not used).

It is important to understand that when you switch the type of connection, the router may require rebooting the network interfaces, at which point the Wi-Fi connection may be interrupted for a short time, do not panic and wait for the settings to be applied, after which you may need to reconnect to the wireless network.

Entering and maintaining records

After selecting the PPPoE connection type, the username field will appear below, enter the username provided by the provider. Note the letter register: most logins are written in lowercase letters, but there may be exceptions.

In the Password field, enter the appropriate password. Be extremely careful when entering, as visual verification is limited here. An error in even one character will result in the router not being able to log in on the server side.

Below are usually additional options such as "Connect automatically" and "Keep alive" and it is recommended to check the automatic connection so that the router itself restores communication after power failures or line breaks.

⚠️ Warning: Don't confuse the Wi-Fi password with the PPPoE password. These are two different settings. PPPoE is only needed by the router to communicate with the provider, it is not used anywhere else.

After filling the fields, press the Save or Apply button. The router will start checking the data entered. The Wide Area Network indicator (usually a blue or green ball) should catch fire if the connection is established successfully.

Cloning MAC-Addresses and additional parameters

Some providers link access to the Internet over MAC-If you previously connected to the Internet directly through a computer, the provider's server might have "noticed" the Internet" MAC-Your PC address. In this case, the router has its unique MAC-The address may be blocked.

To solve this problem, PPPoE settings often have a Clone feature. MAC Address (Cloned) MAC-When you press this button, the router will copy it. MAC-The address of the device from which you set up, in your WAN-It's the easiest way to get around the tether.

Also in advanced settings, you can change the MTU (Maximum Transmission Unit) standard value is 1500 or 1492 for PPPoE. Change this setting is unnecessary, but if you have problems opening some sites or loading pages, you can try to reduce the MTU value to 1400.

If cloning MAC-address did not help, contact the technical support provider and ask to reset the binding MAC-They're on their side, and this service is usually free and can be done remotely in minutes.

💡

Save a screenshot of the WAN settings. Take a screen photo with logins and passwords entered in case you reset your settings in the future, which will save time searching for data in the contract.

Diagnostics and elimination of connection errors

If the Internet does not appear after saving the settings, the WAN indicator on the router may burn red or flash. The web interface in the status section often displays an error code. The most common error is 678 or 691, which indicates an incorrect username / password or no server response.

First, double-check the data you entered. Make sure that the keyboard didn't have Caps Lock on and that the correct language layout is chosen. Often users accidentally type characters in Russian instead of English.

The second step is to check the physical cable. WAN-cable or reconnect it to another port if the router model allows flexible port configuration, and it is also worth rebooting the provider's equipment (if you have one in your apartment), as it could freeze.

⚠️ Warning: If the router writes "Cable unplugged," the problem is exactly at the physical level.

In difficult cases, updating the router firmware can help. Go to Settings → Status → Check for updates. The new version of the software may contain compatibility patches with the equipment of specific providers.
