How to set up a guest Wi-Fi network on a Xiaomi router: full instructions with security tips

The guest Wi-Fi network on Xiaomi’s router is a separate, restricted access point that allows guests to connect to the Internet without accessing your main LAN, an approach that protects personal data, files on network drives and smart devices from prying eyes. Setup takes no more than 5 minutes, but requires attention to detail, from choosing a network name (SSID) to speed and time limits.

In this article, you will find step-by-step instructions for all popular Xiaomi routers models (including Mi Router 4A, 4C, AX3000, AX6000, and others), as well as answers to frequent questions: how to change the password of a guest network, why it does not work after a router restarts, and how to restrict access to certain sites. We will also discuss the unique features of Xiaomi firmware that are not available in other brands’ routers, such as automatic shutdown of the guest network on a schedule.

Why you need a guest Wi-Fi network and how it differs from the main one

The main difference between the guest network and the main one is the isolation of traffic, and when a guest connects to your Wi-Fi via guest access, they:

• 🔒 Does not see other devices on your local network (printers, NAS, lightbulb).
• 📉 Can't access shared folders or router admin panels.
• ⏱️ Speed limit (if you set the limit).
• 🕒 Automatically shuts down after a predetermined time (option available in new firmwares).

Without a guest network, all connected devices are on the same network, which creates risks:

• 🖥️ An attacker can scan your network for vulnerable devices (such as old ones). IP-camera).
• 📂 If you have a Samba setup or FTP, The guest may try to find a password to the shared folders.
• 🎮 Children or neighbors may accidentally change the settings of smart devices (for example, turn off the lights through Mi Home).

On Xiaomi routers, the guest network supports 802.11n/ac/ax (depending on the model), which allows you to connect up to 32 devices simultaneously without significant loss of speed. However, there are limitations: for example, on Mi Router 4A, the guest network only operates in the 2.4 GHz band, and on AX6000 - in both (2.4 GHz and 5 GHz).

Preparing the router for setting up: checking the firmware and resetting settings

Before creating a guest network, make sure that your router has the latest firmware installed. Outdated versions may not support some features (such as a time limit).

1. Open the router's admin panel at 192.168.31.1 (or miwifi.com).
2. Log in (the username and password is usually a combination of admin + password from the sticker on the router).
3. Go to the General Settings section → Status of the system.

If the firmware version is older than 2022, update it:

1. Download the latest firmware for your model from the official Xiaomi website.
2. In the admin panel go to Additional → Software update.
3. Download the firmware file and wait for the process to be completed (the router will restart automatically).

If the router was previously configured by another person or you do not remember the password, reset to factory settings:

1. Press and hold the Reset button on the back of the router (10-15 seconds).
2. Wait for all the indicators to flash and automatic reboot.
3. Connect to the network. Xiaomi_XXXX (password is on the sticker).

⚠️ Warning: Reset removes all settings, including the main Wi-Fi network, forwarding ports and parental controls. VPN, Write down the connection parameters in advance.

Step-by-step: how to create a guest network on the Xiaomi router

The process of setting up the guest network is the same for most Xiaomi models, but may vary slightly depending on the firmware version.

1. Open the router's admin panel by going to 192.168.31.1 or miwifi.com.
2. Log in (by default login – admin, password – from the sticker on the router or the one you installed earlier).
3. Go to the Wi-Fi → Guest network (on some firmware, the path may look like Additional → Guest network).
4. Activate the guest network by ticking next to Enable the guest network.
5. Set up the settings: Network name (SSID): Think of a unique name (for example, Guest_Xiaomi). Don't use the name of the main network! Password: minimum 8 We recommend using a password generator. 2.4 GHz (for compatibility with older devices) or 5 GHz (for high speed): Speed limit: specify maximum speed (e.g, 50 Mbps, so that guests do not occupy the entire channel.

Save.

Name of the network (SSID) different|Passwords contain at least 8 characters|The correct range (2.4 or 5 GHz) is selected)|Speed limit set (optional)|The "Guest Network" is active.-->

Once saved, the guest network will appear in the list of available Wi-Fi. To connect to it, guests will need to enter the password you specified. Note: on some models (for example, Mi Router 4A), the guest network only works in the 2.4 GHz band, even if the main network supports 5 GHz.

⚠️ Attention: On routers with MiWiFi firmware ROM (Like Mi Router. 3G) The guest network may shut down after restarting. To avoid this, upgrade to the latest version of the firmware or install an alternative (for example, Padavan).

Additional settings: speed limit, schedule and parental controls

The basic guest network setup allows you to connect to the Internet, but does not protect against abuse. To make the network more secure and manageable, use these features:

Speed Limitation (Bandwidth Control)

If guests are actively downloading files or watching 4K videos, they can take up the entire Internet channel.

1. In the admin panel go to the Guest Network → Additional settings.
2. Find the Speed Limitation section.
3. Specify the maximum download/return speed (e.g. 50 Mbps for download and 20 Mbps for rebound).
4. Save the settings.

On the AX6000 and AX3000, you can configure the restrictions separately for 2.4 GHz and 5 GHz. For example, for 2.4 GHz, set 30 Mbit / s, and for 5 GHz - 100 Mbit / s.

2. Guest network schedule

If you only need a guest network at a certain time (for example, from 9:00 to 22:00), set the schedule:

1. Go to the Guest Network → Schedule.
2. Activate the option to Enable on schedule.
3. Specify the days of the week and time intervals (for example, PN-Vs, 09:00-22:00).
4. Save the settings.

💡

If you only need a guest network on the weekend, set up a schedule at SB-S, 10:00-23:00, which will reduce the load on the router on weekdays and increase security.

3. Parental controls for the guest network

To limit access to certain sites (such as torrents or social media):

1. Go to the Supplementary → Parental control.
2. Create a new rule for the guest network.
3. Add websites or keywords to a blacklist (e.g. torrent, vk.com).
4. Specify the time of the restrictions.

2. Disable access to the local network

By default, the guest network on Xiaomi is isolated, but in some firmware, this setting can be changed accidentally.

1. Go to the Guest Network → Additional settings.
2. Make sure that Allow guests to access my local network is disabled.

3. Set up the filtering to MAC-address

If you want to allow only certain devices to connect:

1. Find it. MAC-addresses of trusted devices (they are specified in the Wi-Fi settings on the smartphone / laptop).
2. In the admin panel of the router go to Wi-Fi → Filter MAC-address.
3. Add addresses to the whitelist and activate filtering.

⚠️ Attention: Filtration by MAC-The address is not one hundred percent protected, because MAC You can fake it. Use it as an extra security measure.

4. Track connected devices

Check regularly which devices are connected to the guest network:

1. Go to State → Devices on the network.
2. View the list of connected devices in the Guest Network section.
3. If you see an unfamiliar device, lock it down. MAC-address or change password.

Comparison of guest network on Xiaomi and other brands

The guest network on Xiaomi routers has several unique features compared to TP-Link, ASUS or Keenetic:

Xiaomi’s main advantage is its Mi Wi-Fi management app, which allows you to turn on/off the guest network remotely and configure notifications for new connections. However, in terms of security, ASUS and Keenetic routers offer more flexible tools (for example, AiProtection on ASUS or Family Control on Keenetic).
