How to connect to the Xiaomi Mi Router 4A router: all ways and solutions to problems

Xiaomi Mi Router 4A is one of the most popular budget routers from Xiaomi, combining stable operation, simple configuration and support for proprietary technologies such as Mesh network and management through the Mi Home application. However, even with such a device, users sometimes have difficulties when connecting first or after resetting. In this article, we will discuss all possible ways to connect to the router, from standard Wi-Fi to alternative methods through Ethernet and mobile application.

It’s important to understand that the connection process can vary depending on whether you’re setting up your router from scratch (after buying) or trying to access an already running device. We’ll look at both scenarios, as well as the typical bugs that prevent a successful connection. If you’re faced with a router not giving out a IP- address, not opening a control panel, or requiring a password you don’t know, here you’ll find solutions.

1.Preparation for connection: what to check before starting

Before you start connecting, make sure that all the conditions for successful configuration are met. Often problems arise from small things that users do not pay attention to.

First, check the completeness of the router. In the box with Xiaomi Mi Router 4A should be:

• 📦 Router itself with antennas (if the model supports removable antennas)
• 🔌 Power supply (12V/1A or 12V/0.5A depending on version)
• 📃 Brief instruction (usually in several languages, including Russian)
• 📶 Ethernet cable (not always included, but needed to connect to the provider)

Secondly, look at the router's location, and for a stable signal:

• 📡 Install the device in the middle of the apartment, away from thick walls and metal objects
• 🔋 Do not hide the router in closed cabinets – this worsens cooling and signaling
• 🌐 Place antennas vertically (if removable) for better coverage

⚠️ Warning: If you connect a router to the Internet via a cable from a provider, make sure it is not physically damaged, and a damaged cable can cause an unstable connection or a complete lack of access to the network.

2. Connect to the router via Wi-Fi (main method)

The most common way to connect to Xiaomi Mi Router 4A is through a wireless network. By default, the router creates an open network called Xiaomi_XXXX (where XXXX are the last symbols of the MAC- addresses). If the router is new, you do not need a password for the first connection.

Instructions for connection:

1. Turn the router on and wait until the power indicator lights up in blue (this means the device is ready to go).
2. On your smartphone, laptop or tablet, find the Xiaomi_XXXX list of available networks and connect to it.
3. After connecting, the quick setup page will automatically open (if not, enter miwifi.com or 192.168.31.1 in your browser).
4. Follow the instructions of the setup wizard: select a language, set a network name (SSID) and password, set up an Internet connection (if there is a cable from the provider).

If the router has been configured before, but you forgot the Wi-Fi password, you can:

• 🔍 View the password on the sticker on the lower panel of the router (if it has not changed)
• 🔄 Reset router settings to factory (press Reset button for 10 seconds)
• 📱 Connect via the Mi Home app if the router is linked to your Xiaomi account

⚠️ Warning: If you have a "No Internet access" error when you connect to the network Xiaomi_XXXX, that's OK. The router is not set up yet, so there's no Internet. Continue setting up via miwifi.com.

3. Connection via Ethernet cable (alternative method)

If Wi-Fi connectivity is not possible (for example, due to a wireless module malfunction or severe interference), you can use a wired connection. This will require an Ethernet cable (usually bundled with a router or purchased separately).

Step-by-step:

1. Connect one end of the cable to the LAN-port on the router (usually yellow).
2. Connect the other end to the Ethernet port of your computer or laptop.
3. Make sure that the indicator of the corresponding LAN-port is on the router.
4. Open your browser and enter 192.168.31.1 or miwifi.com.
5. If the page does not open, check the network connection settings on your computer: IP- address must be obtained automatically (DHCP).

Advantages of wired connection:

• 🚀 Higher speed and stability of connection
• 🛡️ Less risk of data interception compared to Wi-Fi
• 🔧 Easy to set up initially if Wi-Fi is not working

💡

If you don’t have an Ethernet port on your laptop (like a modern MacBook), use a USB-Ethernet adapter.It’s inexpensive and connects via USB-Type C or USB-A.

4. Connect via the Mi Home app (for smartphones)

The Mi Home app allows you not only to control the router, but also to connect to it bypassing the standard web panel, which is convenient if you prefer to configure devices from a smartphone or have problems logging in through the browser.

Instructions for connecting via Mi Home:

1. Download and install the Mi Home app from Google Play or the App Store.
2. Sign up or sign in to your Xiaomi account (required!).
3. Click Add Device (+ in the upper right corner) and select the Router category.
4. Follow the instructions on the screen: the application will prompt you to connect to the router network (if it is new) or enter a password (if the router is already configured).
5. After successful connection, the router will appear in the list of your devices.

You can use Mi Home to:

• 📶 Change the name and password of Wi-Fi
• 🔄 Update the router's firmware
• 📊 View traffic and connected device statistics
• 🔒 Set up parental controls and guest network

⚠️ Warning: If the router was previously linked to another Xiaomi account, you will need to reset it to factory settings. Otherwise, the connection via Mi Home will not be possible without the previous owner's data.

5. Connect to the router after resetting settings

If you forget your Wi-Fi password or the router control panel is no longer available, the only way to get access back is to reset to factory settings. On Xiaomi Mi Router 4A, this is done using the Reset button, which is on the back of the device.

How to reset your settings:

1. Take a sharp object (a toothpick, a paperclip) and press the Reset button.
2. Hold it for 10-15 seconds until the indicators on the router start flashing yellow or orange.
3. Release the button and wait for the reboot (the router will return to factory settings).

After discharge:

• 🔄 The router will create an open network Xiaomi_XXXX (as in the first connection)
• 🔐 All previous settings (including Wi-Fi password) will be deleted
• 📱 Mi Home app will require device re-association

Important: If the router was linked to a Xiaomi account, it will automatically unplug after the reset, and you will need to re-authorize it to manage it again via Mi Home.

💡

Resetting is a last resort, before you try to restore access through the Mi Home app or contact Xiaomi support if the router is tied to someone else’s account.

6. Solving common connection problems

Even with the right actions, users sometimes encounter errors, and let's look at typical situations and how to solve them.

1 problem: The router does not issue a IP- address ("Unconnected" error)

• 🔌 Check if the DHCP- server is enabled in the router settings (miwifi.com → Settings → Local Network).
• 🖥️ On your computer, run commands in the command line: ipconfig /release ipconfig /renew
• 🔄 Reboot the router and the device you're connecting from.

Problem 2: The page miwifi.com is not open

• 🌐 Try alternative addresses: 192.168.31.1 or d.miwifi.com.
• 🔍 Check to see if the antivirus or firewall is blocking access.
• 📱 Connect via another browser (such as Chrome or Firefox) or device.

Problem 3: The router requires a password, but you don’t know it

• 🔍 See the password on the sticker below the router (if it hasn't changed).
• 🔄 Reset settings with the Reset button.
• 📞 Contact Xiaomi if your router is linked to someone else’s account.

7. Additional settings after connection

After successfully connecting to Xiaomi Mi Router 4A, it is recommended to perform several important settings to improve the security and stability of the network.

1. Change of the standard password

By default, many routers use simple passwords (such as admin or a combination of MAC- addresses) to protect the network:

1. Go to miwifi.com → Settings → System → Administrator Password.
2. Create a complex password (at least 8 characters, with numbers and letters).
3. Save the changes.

2. Guest network setup

The guest network allows you to distribute the Internet without access to the main network (for example, for friends or smart devices).

1. Go to miwifi.com → Settings → Wi-Fi → Guest network.
2. Activate the option and set a name (SSID) and password.
3. Limit the speed for guests if necessary.

3. Firmware update

Regular updates improve the stability and security of the router.

1. Go to miwifi.com → Settings → Firmware update.
2. Click Check for updates.
3. If a new version is available, follow the instructions on the screen.

💡

To keep your router running smoothly, turn off automatic firmware updates at night, which will prevent unexpected reboots if you use the internet for work or streaming.
