How to improve the network on Xiaomi: from weak signal to stable Wi-Fi

Weak Wi-Fi signals, persistent connection breaks or low Internet speeds on Xiaomi devices are a familiar problem? You are not alone: according to statistics, one in three users of smartphones and routers of the brand encounters a network that works β€œonce again”, the reasons can lie in the settings of the device itself, and external factors – from an overloaded channel to outdated firmware.

In this article, we’ll look at 10 proven ways to improve the network on Xiaomi, including smartphone settings, router optimization, and even hardware solutions. Importantly, the methods will work for most models, from the budget Redmi Note to the flagship Xiaomi 14, as well as for routers Mi Router and AiOT Router. Some tips are universal, others require technical knowledge – choose the right ones.

Before you start settings, make sure that the problem is not on the provider's side.

  1. Connect to the same network another device (laptop, tablet).
  2. Check the speed at Speedtest.
  3. Restart the router (turn off power for 30 seconds).

If other gadgets are stable, the problem is the settings Xiaomi. If not, contact the provider or check the router.

1. Optimization of Wi-Fi settings on Xiaomi smartphone

To start with, the most obvious is the network settings on your Xiaomi, and users often don’t even realize that standard settings can (and should!) be adjusted for better performance.

The first thing you should do is turn on Smart Switch mode (if supported by your model), which automatically switches the device between Wi-Fi and the mobile network if the signal becomes too weak.

  1. Go to Settings β†’ Connections and Sharing β†’ Wi-Fi.
  2. Slip on three dots in the upper right corner and select Additional Features.
  3. Find the Smart Switch option Wi-Fi/Mobile data and turn it on.

The second important thing is to change the Wi-Fi region, and Xiaomi's default is often China, which limits the number of channels available.

  1. Activate Developer Mode (7 times tap on the MIUI version in Settings β†’ About Phone).
  2. Back to Settings β†’ Additionally. β†’ For developers.
  3. Find the Wi-Fi Region and choose Europe or the United States (depending on your location).

πŸ’‘

If after changing the region Wi-Fi stopped working at all, return the settings to the factory (Settings) β†’ System system β†’ Resetting settings β†’ Resetting network settings).

Also check if your Xiaomi has Wi-Fi power saving on, which limits background network activity, which can cause connection breakdowns.

  • Settings β†’ Battery and performance β†’ Energy saving regime β†’ Select No Limitations for Wi-Fi.

2. Choosing the right channel and frequency on the Xiaomi router

If the problem is not with the smartphone, but with the router, the first thing to do is check which channel and frequency is used to transmit the signal. By default, many Mi Routers run on congested channels (for example, 6 or 11), which leads to interference.

To change the channel:

  1. Connect to the router’s web interface at 192.168.31.1 (the username and password is usually admin).
  2. Go to Settings. β†’ Wi-Fi (or Wireless Mode).
  3. In the Channel section, select Auto or manually specify a channel from 1 to 13 (2.4 GHz) or 36 to 165 (5 GHz).

To choose the best channel, use applications like WiFi Analyzer (Android) or NetSpot (Windows/macOS). They will show you which channels are least loaded in your area.

FrequencyAdvantagesDeficienciesRecommendations
2.4 GHzLong range signal, better passes through wallsLow speed, subject to interference from other devicesUse for devices away from the router (such as smart lamps)
5 GHzHigh speed, less interferenceLess range, worse passes through obstaclesUse for smartphones, laptops and TV near the router
6 GHz (Wi-Fi 6E)Maximum speed, minimum interferenceVery limited range, not supported by all devicesOnly for the latest flagships (e.g. Xiaomi 13 Ultra)

A critical nuance for Xiaomi routers: if you have a dual-band router (for example, Mi Router) AX6000), Make sure to divide 2.4 GHz and 5 GHz networks into different ones. SSID (This will allow devices to select the optimal frequency automatically.

3. Update of the router and smartphone firmware

Outdated software is one of the main causes of network problems, and manufacturers regularly release updates to fix bugs and improve the stability of Wi-Fi.

To update the firmware on Mi Router:

  1. Go to the router's web interface (192.168.31.1).
  2. Go to Settings. β†’ System system β†’ Firmware update.
  3. Click Check for updates and, if any, install them.

For Xiaomi smartphones:

  1. Open Settings β†’ About the phone β†’ System update.
  2. Click Check for updates.
  3. If you have a new version of MIUI or HyperOS, install it.
What to do if the update is suspended?
If the router or smartphone is stuck during the update: 1. For the router: turn off the power for 10 seconds, then turn on again. If it does not help, reset the settings with the Reset button (hold 10 seconds). 2. For the smartphone: hold the power button 15+ You need to force reset, if it doesn't work, you need to shut down the power. + Volume up to log into Fastboot and reset via Mi Flash Tool.

After the upgrade, be sure to restart the device. Sometimes the new settings take effect only after the reboot.

4. QoS setup and traffic prioritization

QoS (Quality of Service) is a technology that allows a router to prioritize bandwidth between devices, for example, you can give a maximum speed to a smartphone, and a smart lamp a minimum.

To set up QoS on Mi Router:

  1. In the web interface, go to Settings β†’ QoS.
  2. Turn on the function and select Priority mode by device.
  3. Add in. MAC-Device addresses that need priority (find) MAC You can use Wi-Fi settings on your smartphone).
  4. Specify the desired bandwidth for each device (e.g., 70% for smartphone, 10% for TV).

Mi Router also has a Game Turbo feature that automatically optimizes the network for online gaming and streaming, and it is enabled in the Mi WiFi mobile app:

  • Open the app and select your router.
  • Go to the Tools. β†’ Game accelerator.
  • Turn on the feature and add games/applications that need to speed up the network.

πŸ’‘

QoS is especially useful if you have multiple devices on the network (10).+). Without prioritization, the router will β€œstrangle” traffic for everyone, which will lead to lags and low speeds.

5 Signal amplification: from router location to antennas

If all the software methods have been tried and the network is still slowing down, it’s time to pay attention to the physical factors, and even the most powerful Xiaomi router will not save you if it is in the wrong place.

Here are the basic rules for placing a router:

  • πŸ“ Central position: the router should be as close to the center of the apartment / house as possible so that the signal is evenly distributed throughout the rooms.
  • 🚫 Avoid obstacles: walls, furniture, appliances (especially microwaves!) weaken the signal.
  • ⬆️ Height: optimally place the router at a height of 1-2 meters from the floor (for example, on a shelf or wall).
  • πŸ“Ά Antennas: if the router has external antennas (for example, Mi Router) AX9000), Place them at an angle of 45-90 degrees to each other for better coverage.

If even after reshuffling the router, the signal is weak in some rooms, consider the following solutions:

  • πŸ”„ Repiter: Devices like the Xiaomi Mi Wi-Fi Range Extender amplify the signal in the "dead zones", connect to the outlet and repeat the router network.
  • πŸ”— Mesh system: If you have a large house, it is better to use Mesh routers (such as Xiaomi Mesh System) that create a single network without losing speed.
  • πŸ“‘ External antenna: for advanced users, you can buy a gain antenna (for example, 9 dBi) and connect it to the router instead of the standard one.

The router is in the center of the apartment / house

There are no major obstacles (walls, furniture) between the router and the devices.

The antennas are pointing in different directions (not parallel!).

The router does not stand next to household appliances (microwave, refrigerator)

Ethernet cable is used 5e or higher (if the router is connected to the provider by wire)-->

6. Reset network and router settings

If none of these things worked, maybe the problem is a setup conflict, and then a complete reset of the network settings on your smartphone or router will help.

To reset network settings on Xiaomi:

  1. Go to Settings β†’ System β†’ Resetting settings.
  2. Select Network Reset (not to be confused with a full reset!).
  3. Confirm the action and restart the device.

To reset the Xiaomi router to factory settings:

  1. Find the Reset button on the back of the router (usually recessed in the case).
  2. Take a paperclip or toothpick, press and hold the button for 10-15 seconds until the indicators start flashing.
  3. Once reset, the router will restart and you can reconfigure it through 192.168.31.1.

πŸ’‘

Before resetting your router, record or photograph your current settings (network name, password, channel, QoS) and save time when resetting.

After the reset, remember:

  • Update the router to the latest version.
  • Change the standard network name (Xiaomi_XXXX) and a password for a more secure.
  • Set up QoS and prioritize traffic again.

Alternative methods: from DNS before VPN

Sometimes the problem isn't Wi-Fi itself, but how the device interacts with the network. Let's look at some non-obvious but effective ways to improve connectivity.

1. Shift DNS-server

By default, providers use their DNS, They can work slowly. Replace them with faster ones:

  1. On a smartphone: Settings β†’ Connections β†’ Private DNS β†’ Select the host name of the private provider DNS and type dns.google (Google) or 1dot1dot1dot1.cloudflare-dns.com (Cloudflare).
  2. On the router: in the web interface, find Settings β†’ Internet β†’ DNS and specify 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).

2.Use of VPN

If the provider artificially restricts the speed (trottling), VPN This can help you get around this limitation:

  • ProtonVPN (free rate with speed limit).
  • Warp by Cloudflare (optimized for low ping)
  • NordVPN (paid, but with servers for streaming and games).

3. Disable IPv6

In some cases IPv6 may conflict with IPv4, It slows down the network, so you can turn it off on your smartphone:

  1. Go to Settings β†’ Connections β†’ Wi-Fi.
  2. Slip on your network and select Change the network.
  3. In the section IP-settings select IPv4 (instead IPv4/IPv6).
How to check if the change helps DNS?
Do a speed test before and after the change DNS If the ping went down and the speed went up β€” DNS problem.

8 Hardware Solutions: From Amplifiers to Router Replacement

If the software methods don't work, maybe it's hardware. Let's look at what we can do on the physical level.

Signal amplifier (booster)

Devices like TP-Link TL-WA850RE Or Xiaomi Mi Wi-Fi Amplifier plugs into the outlet and repeats the router signal, increasing the coverage area.

2. Replacement of antennas

If your router has removable antennas (for example, Mi Router) 4A Gigabit, which can be replaced with more powerful antennas, are 7-9 dBi antennas, and it is important that antennas that are too powerful (for example, 15 dBi) can, on the contrary, degrade the signal due to the narrow directional direction.

3. Network cable laying

If you have fixed devices (such as a Mi Box or laptop), the best solution is to connect them to the router via an Ethernet cable. This guarantees maximum speed and stability. 5e or 6 for speeds up to 1 Gbps.

4. Router replacement

If your router is older than 3-4 years, it may not be able to cope with modern loads.

  • Mi Router AX6000 β€” for large houses (coverage up to 200 m2, Wi-Fi 6).
  • Mi Router 4C β€” Budget option for apartments (Wi-Fi 5, up to 100 mΒ²).
  • AiOT Router AX3600 β€” Smart home support (Zigbee and Matter support).

πŸ’‘

If you have more than 20 devices on the network (smartphones, lamps, sensors), the router should support the network. MU-MIMO and OFDMA (Otherwise, the network will β€œbrake” due to overload.

When choosing a new router, pay attention to:

  • πŸ“Ά Wi-Fi standard: Wi-Fi minimum 5 (802.11ac), Better than Wi-Fi 6 (802.11ax).
  • πŸ”„ Number of antennas: 4 or more for better coverage.
  • πŸ–₯️ Ethernet ports: at least 1 Gigabit port (1000 Mbps).
  • πŸ”’ Support WPA3: more secure encryption protocol.

FAQ: Frequent questions about improving the network on Xiaomi

Why is Wi-Fi on Xiaomi slower than on other devices?
This may be due to: Wi-Fi region (the default is often China, which limits channels); energy-saving settings (MIUI It restricts background Wi-Fi. It's outdated firmware on your smartphone or router. Try changing Wi-Fi to Europe and turning off the power savings for the grid.
How to find out which Wi-Fi channel is the most free?
Use network analysis apps: WiFi Analyzer (Android) - shows real-time channel load (Windows/macOS) β€” It's building a heat map of the signal (iOS/Android) β€” Analyzes all the devices on the network. Choose a channel with as few other networks as possible (ideally none at all).
Will the Mesh system help if I have a big house?
Yes, if: The house is over 100 m2. There are many "dead zones" (rooms where the signal goes missing); you need seamless switching between access points (for example, for video calls on the go). AX6000 + Mi Wi-Fi Amplifier.
Can I improve Wi-Fi without buying a new router?
Yes, try: Move the router to the center of the apartment; change the channel and frequency (from 2.4 GHz to 5 GHz or vice versa); update the router's firmware; connect the repeater; or use Powerline adapters (wiring Internet transmission); if nothing helps, the router could indeed become obsolete.
