How to connect and configure the Xiaomi Mi Wi-Fi Router 4A Gigabit Edition router: the full guide

Why you need a Gigabit Edition and how it differs from the regular version

Xiaomi Mi Wi-Fi Router 4A Gigabit Edition (also known as Giga Version) is an advanced model of Xiaomi’s popular budget router, which has Gigabit ports and improved performance. 4A portable 100 Mbps, this modification supports speed up to 1000 Mbps LAN/WAN-Ports, which is critical for modern Internet tariffs over the Internet 100 Mbit/s.

Connecting Gigabit Edition is easier than it seems, but there are nuances: from choosing the right cable to setting up a dual frequency of 2.4 GHz + 5 GHz. In this article, we will analyze the step-by-step connection, basic configuration through the Mi Wi-Fi mobile application and web interface, as well as solving typical problems (for example, why the router does not give gigabit speed even when connecting to a 1000 Mbps port).

If you’ve just unpacked your device or are planning to replace your old router, this will save you time, and we’ll skip the technical details, but point out the critical points that Xiaomi doesn’t describe in the official documentation (for example, why it’s better not to use a factory Wi-Fi password).

Compilation and preparation for connection

Before you connect the Mi Wi-Fi Router 4A Gigabit Edition, check the package.

• 📦 The router itself (white or black, depending on the batch)
• 🔌 Power supply 12V/1A European or Chinese fork (adapter may be needed)
• 📶 Patch cord Cat.5e (usually yellow, 1 meter long)
• 📄 Brief instruction in Chinese/English (no Russian version)

Important: If your ISP is over 100 Mbps, replace the factory patch cord with a Cat.6 cable or higher. Cheap Cat.5e cables may not deliver a stable 1000 Mbps over long distances (over 15 meters).

Also prepare:

• 📱 Smartphone with Mi Wi-Fi app (available for Android and iOS)
• 💻 Laptop or PC (to be configured via web interface if mobile application is not suitable)
• 🔍 Data from the provider: type of connection (DHCP, PPPoE, Static IP), login/password (if necessary)

⚠️ Note: If your provider uses a binding MAC-Please specify in advance if you need to clone. MAC The old router. 4A Gigabit Edition is available in the web interface (Advanced) → MAC Clone).

Connecting the router to the network: step-by-step instructions

Now, let's move on to physical connectivity, and follow this algorithm to avoid the typical errors.

1. Select a router seat. Place it in the middle of the apartment, away from microwaves, radio phones and other sources of interference. The Gigabit Edition has two external antennas, but they won't save you from thick walls.
2. Put the power in the router, then the socket. The indicator on the front panel should light up orange (boot mode).
3. Connect the router to the Internet. Use a patch cord to connect the WAN port (usually highlighted in blue) to the cable from the provider.
4. Connect the device to the router. Insert the second end of the cable from the kit into the LAN port (yellow) and connect to the PC / laptop OR connect to the factory Wi-Fi network (name is indicated on the sticker at the bottom, the password is admin or empty).

Power supply connected | Provider's cable in WAN| Device connected to router (LAN or Wi-Fi) | Mi Wi-Fi application launched or browser-->

After connecting, wait until the indicator on the router turns blue (work mode). If it flashes orange, check the provider's cable or restart the router with the Reset button (hold 5 seconds).

Configure via the Mi Wi-Fi mobile application

The easiest way to set up the Xiaomi Mi Wi-Fi Router 4A Gigabit Edition is to use the official app.

• 🤖 Android (Google Play)
• 🍎 iOS (App Store)

After installation:

1. Open the app and select Add the device.
2. Press the Router and wait until the app finds the Mi Router 4A Gigabit Edition.

💡

If the app doesn’t find the router, check if you’re connected to its Wi-Fi network, and try to turn off the VPN or mobile internet on your smartphone.

Once you save the settings, the router will restart, which can take up to 2 minutes, if the Internet does not appear after the reboot:

• 🔄 Reconnect the provider's cable.
• 📱 Check if the username/password for PPPoE is correctly entered.
• 🌐 Try connecting to the router via the browser (address: 192.168.31.1).

Configuring through the web interface: advanced features

The mobile app is convenient, but does not allow access to all functions. For fine-tuning (for example, port forwarding, guest Wi-Fi or bandwidth control), use the web interface:

1. Connect to the router network (via Wi-Fi or cable).
2. Open the browser and enter 192.168.31.1 in the address bar.
3. Log in (login: admin, password: admin or the one you set up).

The main sections of the web interface:

One of the most useful sections is Advanced → QoS (Quality of Service), where you can prioritize traffic, like maximizing speeds for online games or video calls.

1. Turn on the QoS.
2. Select Custom and add rules for the right devices or applications.
3. Save the settings and restart the router.

⚠️ Warning: If you have turned on QoS but notice a speed drawdown, turn it off. At weak rates (100 Mbps), this feature can create delays.

Speed check and diagnosis of problems

After setting up, check if the router is giving the speed it says it should.

1. Connect your PC to your router with a cable (Wi-Fi is always slower).
2. Run a speed test on Speedtest.net or Fast.com.
3. Compare the result with the provider’s tariff.

If the speed is lower than expected:

• 🔌 Check that the cable is connected to a gigabit port (it is usually signed on the router). 1000M).
• 🔄 Restart the router and modem provider (if any).
• 📊 In the web interface (Status) see how fast the provider gives on the port WAN.

For diagnosis, you can also use built-in router tools:

1. Get in Advanced. → System Tools → Ping Test.
2. Enter the address (e.g. 8.8.8.8 Google DNS).
3. If packets are lost (Request timed out), the problem is on the provider’s side.

Security: How to Protect Your Network

The Mi Wi-Fi Router 4A Gigabit Edition's factory settings don't provide adequate protection.

• 🔐 Change the administrator password. It's admin by default, easy to find. Use a combination of 12.+ symbols with numbers and special signs.
• 🛡️ Turn it off. WPS. This feature is vulnerable to brute force attacks. Find an option in Wireless → WPS and deactivate it.
• 🔄 Update the firmware. In the web interface (Advanced) → System Tools → Firmware Upgrade) check the relevance of the version. Xiaomi regularly releases security patches.
• 👤 Set up a guest network. For friends or smart devices (like cameras), create a separate network with limited access to local resources.

We also recommend:

• Use WPA2-PSK encryption (in Wireless settings). WPA3 is not supported on this router.

💡

Even if your Wi-Fi password is complex, turning off WPS and updating your firmware regularly will reduce your risk of being hacked by 80%.

Frequent problems and their solutions

Here are the typical errors when connecting Xiaomi Mi Wi-Fi Router 4A Gigabit Edition and how to fix them:

If the router is constantly restarting or “hanging”, try:

1. Disable QoS and IPv6 (if not used).
2. Reset the settings to factory (Reset).
3. Update the firmware manually (download the file from the official Xiaomi website).

⚠️ Warning: If the router stopped turning on after the firmware update, try restoring it through emergency firmware mode. To do this, hold Reset when power is turned on until the indicator flashes yellow. Then download the firmware through 192.168.31.1 in the browser.
