How to change settings on the Xiaomi router: from Wi-Fi to firmware

Xiaomi routers (including Mi Router models) 4A/4C/4Q, AX3600, AX6000 Redmi Router AC2100) They offer flexible network settings, but they often raise questions among users, and unlike other brands, they combine a simplified web interface with hidden features for power users. 2023.09 There is an opportunity to prioritize traffic for gaming consoles, and in models with Wi-Fi 6 hand-held 160 MHz.

In this article, we will analyze not only the basic settings (such as changing a password or a network name), but also advanced functions: setting up a guest network with a time limit, creating a new network. VPN-The instructions are valid for the latest firmware 2026.03 and later, given the features of firmware for the Chinese and global markets, and when the Wi-Fi channel is changed.

We will pay special attention to hidden settings that Xiaomi does not advertise in the official documentation, for example, activating the Developer Mode mode to access advanced QoS settings or changing regional restrictions on Wi-Fi channels. These features can significantly improve network stability, especially in apartment buildings with a large number of neighbors.

Preparing for changing settings: entrance to the control panel

You need to connect to the router correctly before you change your settings, and most of the problems you have when you set up are due to errors at this point.

  • πŸ”Œ Connect your device (PC, smartphone or tablet) to the router via cable (recommended) or Wi-Fi. Use the port for cable connection LAN (yellowish).
  • 🌐 Make sure that the connected device is disabled VPN Proxies – they can block access to the control panel.
  • πŸ” In the browser address bar, type 192.168.31.1 (for most Xiaomi models) or miwifi.com. If the page does not open, check the network settings on your device.
  • πŸ”‘ Use the admin login and password on the router sticker (often empty or admin by default) to log in. If the password has changed before but you have forgotten it, you will need to reset your settings.

On Xiaomi models AX6000 and AX9000 Firmware 2026.01 and later may require confirmation via the Mi Wi-Fi app. QR-Install the app on your smartphone and follow the instructions on the screen. This is an additional security measure that you can't turn off.

⚠️ Note: If the router was purchased in the Chinese market (models with suffix) CN In the title, the default web interface may be in Chinese. To change the language, go to the β†’ Choose English or Russian (if available).

Change the name and password of Wi-Fi: basic security settings

Change of network name (SSID) And passwords are the first measure of protection against unauthorized access. Xiaomi routers do this in a few steps:

  1. Go to the Wi-Fi settings section (or Wi-Fi settings in the Russian version).
  2. In the Wi-Fi Name field, type a new network name. Use Latin and numbers - Cyrillic can cause problems on some devices.
  3. In the Wi-Fi Password field, specify a new password. Recommended length is at least 12 characters using capital letters, numbers and special characters (for example,!@#$%).
  4. Select the type of security: WPA2-PSK (recommended WPA3-PSK (For modern devices, avoid outdated devices. WEP β€” easy to crack.
  5. Press Save and wait for the router to restart (usually takes 1-2 minutes).

On models that support Wi-Fi 6 (for example, AX3600) Wi-Fi 6 Mode is available, which improves speed and stability for compatible devices, but can cause problems with older gadgets (released before 2019).If after activating this mode, some devices stopped connecting, return the setting to Auto position.

ParameterRecommended valueExplanation
Channel Width20/40 MHz (for MHz) 2.4 GHz), 80 MHz (for MHz) 5 GHz)The greater width of the canal increases speed, but can cause interference in apartment buildings.
ChannelAuto or manually (e.g. 6 for 2.4GHz)Manual channel selection is useful if neighboring networks cause interference. Use Wi-Fi analyzers (for example, Wi-Fi Analyzer for Android).
Transmit PowerHigh (default)Power reduction (Medium/Low) It may reduce interference but reduce coverage.

Setting up Wi-Fi channels: how to avoid interference and increase speed

Misconception of Wi-Fi is one of the main reasons for slow Internet. 2.4 GHz channels are often overloaded in apartment buildings, and many users leave automatic choices at 5 GHz, which is not always optimal.

To manually select the channel:

  1. Go to Wi-Fi settings β†’ Advanced settings.
  2. For the 2.4GHz band, select a channel from the list of 1, 6 or 11 - they do not overlap with other channels. Avoid 12-14, as they may be banned in your region.
  3. For 5GHz, choose a channel from the 36-48 or 149-165 range (depending on your router's support). 100-140 channels are often used by radar and can cause interference.
  4. Save the settings and restart the router.

To analyze the load of channels, use the applications:

  • πŸ“± Wi-Fi Analyzer (Android) – shows real-time channel loading.
  • πŸ’» inSSIDer (Windows/macOS) β€” Professional tool with Wi-Fi support 6.
  • 🌐 NetSpot – Creates a Wi-Fi Heat Map in Your Home.

On Xiaomi routers AX6000 and AX9000 Smart Channel Selection is available, which automatically selects the least loaded channel, but it doesn't work perfectly: it can ignore interference from microwave ovens (operated at 2.4 GHz). If you notice that the speed drops at a certain time of day, try to turn off this option and set the channel manually.

πŸ’‘

If some devices (such as older smartphones or smart lamps) stop connecting after changing the channel, return the Channel Width setting to 20 MHz for the 2.4 GHz band.

Parental Control and Guest Network: Access Restrictions

Xiaomi’s parental controls feature allows users to limit their Internet access time for individual devices or block certain sites, which is useful if you want to limit the time children spend online or block access to social networks during working hours.

To set up parental control:

  1. Go to Advanced. β†’ Parental Control.
  2. Click Add Rule and select the device from the list of connected gadgets (or add it manually to the list). MAC-address).
  3. For example, you can only allow Internet access from 17:00 to 21:00 on weekdays.
  4. In the Website Filter section, add sites to block (e.g. vk.com, tiktok.com).
  5. Save the rule and activate it.

To create a guest network (isolated from the main one):

  1. Go to Wi-Fi settings β†’ Guest Network.
  2. Activate the guest network and set a separate name for it (SSID) password.
  3. In the guest network settings, you can limit speed (for example, up to 10 Mbit / s) and operating time (for example, only from 9:00 to 18:00).
  4. Check the Isolate Guest Network box so that guest devices cannot interact with devices on the main network.

⚠️ Attention: Parental control on Xiaomi routers works at the level DNS-This means that experienced users can bypass the lock by changing the lock. DNS Use specialized solutions (e.g. OpenDNS or Pi-hole) to securely lock).

On firmware models 2026.02 and later, Device Grouping has been introduced, allowing you to create groups of devices (e.g., "Children", "Working gadgets") and apply rules to the entire group at once.

How to get around parental controls on Xiaomi
If you forgot the password from the router or you need to temporarily disable the restrictions, you can: 1. Connect to the router via cable and reset the settings with the Reset button (hold 10 seconds). 2. Use alternatives DNS (e.g., 1.1.1.1 or 8.8.8.8) on a locked device. 3. VPN on the device (but this will only bypass the blocking of sites, not a time limit).

Advanced settings: QoS, VPN port

For experienced users, Xiaomi routers have features that are rarely mentioned in official instructions.

1. Quality of Service (QoS)

QoS allows you to prioritize traffic for certain devices or data types (e.g., online games or video calls) to configure:

  1. Go to Advanced. β†’ QoS.
  2. Enable QoS and select the prioritization type: By Device or By Application.
  3. To prioritize your device, select a gadget from the list (such as the PlayStation 5 game console) and set a high priority.
  4. To prioritize your application, select the type of traffic (such as Gaming or Video Call).

2. VPN-router

On models AX3600, AX6000 and AX9000 can be tuned VPN-So you can use a server to connect securely to your home network from anywhere in the world:

  1. Go to Advanced. β†’ VPN Server.
  2. Choose a type VPN: PPTP (Simple but less secure) or OpenVPN (recommended).
  3. Set a user name and password to connect.
  4. Download the configuration file (.ovpn) to connect from client devices.

3. Port forwarding (Port forwarding)

If you need to open access to a local server (for example, for Minecraft, NAS or security cameras, use Port Forwarding:

  1. Go to Advanced. β†’ NAT Forwarding β†’ Port Forwarding.
  2. Add a new rule by specifying: External port (e.g. 25565 for Minecraft). IP-Device address (e.g. 192.168.31.100) Internal port (should match external if no broadcast is used (TCP, UDP either).

Save the rule and restart the router.

To check open ports, use services like YouGetSignal or GRC ShieldsUP.

πŸ’‘

Opening ports can create a security vulnerability. Always use complex passwords for local services and update the router's firmware.

Update firmware and reset settings

Regular updates to router firmware are critical for security and stability, with new versions fixing vulnerabilities, adding features (such as Wi-Fi support) 6E into AX9000) It improves compatibility with the devices:

  1. Go to System Status β†’ Firmware Upgrade.
  2. Press Check for Updates. If a new version is available, download it.
  3. Wait for the update to complete (the router will restart automatically). Do not turn off the power during the process!

If the router is unstable (often restarts, loses" the device or does not give out IP-address, you may need to reset your settings:

  1. Press and hold the Reset button on the back of the router (usually it is recessed and requires a paper clip).
  2. Hold the button for 10-15 seconds until the lights start flashing quickly.
  3. Once reset, the router will return to factory settings. Connect to it by default (network name is usually Xiaomi_XXXX, password is on the sticker).

⚠️ Note: On routers with modified firmware (such as Padavan or OpenWRT), resetting the Reset button can cause the device to β€œbrick” and require flashing through the device. UART or TFTP.

If the router stopped turning on after the update (all indicators are on or only one flashes), try:

  • πŸ”Œ Turn off power for 30 seconds, then turn on again.
  • πŸ”„ Download the firmware manually through TFTP (For instructions for your model, look for forums 4PDA Xiaomi Community).
