How to improve the quality of the Internet on Xiaomi smartphones: from settings to hardware solutions

Slow internet on Xiaomi is a problem that even owners of flagship models like Xiaomi 14 Ultra or POCO F6 Pro face. The reasons can lie in the settings of the smartphone itself, as well as in external factors: an overloaded router, weak Wi-Fi signal or limitations on the part of the provider. In this article, we will analyze the system and hardware methods of network optimization that work on all Xiaomi, Redmi and POCO devices running MIUI or HyperOS.

It's important to understand that there's no universal solution. If you have a Wi-Fi speed that falls on Xiaomi, and other devices on the same network are stable, the problem is probably the phone settings. If the Internet is slowing down on all gadgets, it's the router or the provider's fault. We'll look at both scenarios, from the simplest ways to the "heavy artillery" for power users.

1. Checking the current speed and diagnosing problems

Before you change anything, you need to know where the bottleneck is.

• 📱 Run a speed test on your smartphone via Speedtest.net or Fast.com. Compare the results to other devices on the same network.
• 📶 Check the Wi-Fi signal level in Settings → Wi-Fi: If the name of the network is displayed next to the name of the network 1-2 Dividing – the signal is too weak.
• 🔄 Reboot your router (turn it off for 30 seconds) and your smartphone, and 40 percent of the time, it solves temporary crashes.

Pay attention to the ping in the test results:

• 0-50 ms is a great connection.
• 50–100 ms is acceptable for watching videos, but can play online games.
• 100+ ms critical delays, intervention required

⚠️ Note: If the speed on Xiaomi Wi-Fi is lower than on other devices, but the ping is stable (up to 50 ms), the problem is most likely in the phone’s power saving settings (see section 3).

2. Optimizing Wi-Fi settings on Xiaomi

MIUI and HyperOS hide a few parameters that directly affect connection stability.

1. Enable High Performance Wi-Fi: Go to Settings → Wi-Fi → Additional → Wi-Fi Mode and select High Performance. This will turn off the power saving for the network adapter, but can reduce battery life by 5-10%.
2. Turn off automatic switching to mobile data: C Settings → SIM-maps and mobile networks → Switch to mobile data deactivate the option. This feature often works falsely, interrupting downloads.
3. Forget the network and connect again: In the network list, click on your Wi-Fi, select Delete, then connect again. DHCP and IP-settings.

For models with Qualcomm Snapdragon (for example, Xiaomi 13T or Redmi Note 12 Pro+), hidden settings are available:

##4636## → Information about Wi-Fi → Wi-Fi settings → Turn off “packet aggregation”

This option sometimes conflicts with some routers, causing packet loss.

Make sure that the “High Performance” mode is enabled"|Disable automatic switching to mobile Internet|Remove and reconnect to the network|Check for updates MIUI/HyperOS-->

3. Energy saving settings for a stable internet

Aggressive energy saving is one of the main reasons for the “hangover” of the Internet on Xiaomi, the system can limit the background activity of applications (for example, YouTube or Telegram), which leads to downloads or slow messengers.

To fix this:

• 🔋 Open the Settings. → Battery → Battery mode and select Performance (for maximum speed) or Balanced.
• 🚫 B Settings → Annexes → Application management → Autorun Allow Autorun for Critical Programs (e.g. Chrome, Speedtest).
• 🔄 B Settings → Special facilities → Optimization MIUI Turn off background restriction (not available on all models).

For POCO and some Redmi, there is a separate setting:

Settings → Battery → Battery settings → Disable “Network Optimization in the Background”

⚠️ Note: On devices with MediaTek (e.g., Redmi Note 12 or POCO M6 Pro) power saving cuts for Wi-Fi can cause the chipset to overheat during long loads. → The phone. → Status of the system.

4.Selecting the Right Wi-Fi Frequency (2.4GHz vs 5GHz)

Many routers broadcast simultaneously on two frequencies: 2.4 GHz (long-range but low speed) and 5 GHz (high speed but weak signal through walls). Xiaomi defaults to 2.4 GHz, even if 5 GHz is available.

How to force the frequency to be selected:

1. Find out the name of the 5GHz network (usually 5G or -5).
2. In Settings → Wi-Fi, find this network and connect to it manually.
3. If 5GHz is not listed, check your router settings (see Section 6).

If your router supports Wi-Fi 6 (802.11ax), turn it on in your router settings and update your firmware on Xiaomi to the latest version. Xiaomi 12T Pro and newer models have hardware support for Wi-Fi 6, which increases speeds by 30-40%.

💡

If your router does not support 5 GHz, but you have a high-speed tariff (100 GHz).+ Mbps), consider buying a dual-band router. for example, Xiaomi Router AX6000 or TP-Link Archer C6 3,000 ₽ It will unlock the full potential of your internet.

5. Update firmware and reset network settings

Internet problems on Xiaomi are often solved by an update MIUI/HyperOS. The manufacturer regularly fixes bugs in Wi-Fi drivers and mobile networks to check the relevance of the firmware:

1. Go to Settings → About the phone → System update.
2. If you have an update, install it (preferably via Wi-Fi).
3. After the update, reboot.

If the updates don’t help, try resetting your network settings:

Settings → About Phone → Settings Reset → Resetting Wi-Fi, Mobile Data and Bluetooth

This operation will delete all stored networks and passwords, but will not affect personal data.

⚠️ Note: On HyperOS devices (e.g. Xiaomi 14 or Redmi) K70) Resetting network settings may also reset settings VPN And Proxy. Save configurations in advance if you use them.

For advanced users, if the problem persists, you can try flashing your phone manually through Fastboot or Recovery. For instructions for a specific model, look at the Xiaomi.eu or 4PDA forums.

6. Set up a router for maximum compatibility with Xiaomi

If you have Internet problems on all devices, it's the router's fault. Here are the key settings to check:

• 📡 Wi-Fi Channel: In the router control panel (usually 192.168.0.1 or 192.168.1.1), select the channel manually. 2.4 GHz optimal channels 1, 6 or 11 (they do not overlap). 5 GHz channels 36-48 or 149-165.
• 🔒 Type of encryption: Install WPA2-PSK or WPA3-PSK. WEP and WPA Unsafe and may inhibit the connection.
• 📶 Transmission power: If the signal is weak, increase the power to 100% (in some routers this option is hidden in Advanced Settings).
• 🔄 Mode of work: Xiaomi is best suited mode 802.11n/ac/ax (If the router supports, disable outdated standards (802.11b/g).

If you have a dual-band router, divide the networks:

• Create two separate networks: for example, MyWiFi_2G and MyWiFi_5G.
• For Xiaomi, make it a priority to connect to 5G-manually.

For Xiaomi routers (such as Mi Router 4A or AX3600):

Open the Mi Wi-Fi app → Settings → Wi-Fi mode → Enable Smart Switch (if you need to automatically switch between 2.4 and 5 GHz).

💡

If, after all the settings, the Wi-Fi speed on Xiaomi is still lower than on a PC, the problem may be bandwidth limitations on the part of the provider.

7. Alternative ways to improve the Internet

If standard methods don’t help, try these non-obvious solutions:

• 📱 Use the mobile Internet as a reserve: C Settings → SIM-maps and mobile networks → Access Point and modem enable Automatic Switch to Mobile Data (if previously disabled) This will help if Wi-Fi suddenly disappears.
• 🔌 Connect through USB-cable (USB Tethering: If you have Xiaomi support OTG, You can connect your phone to a router or PC via USB And use the Internet, and it's faster than Wi-Fi.
• 🌐 Set up. DNS: B Settings → Wi-Fi → Additionally. → Settings IP Choose a static and write DNS: 1.1.1.1 (Cloudflare) 8.8.8.8 (Google) This will speed up site openings by 10–30%.
• 🛠️ Turn it off. VPN Proxy: Some applications (e.g. 1.1.1.1 or AdGuard) may conflict with Wi-Fi. → Connections → VPN.

For gamers: if you play via Wi-Fi on Xiaomi, turn on the game accelerator mode:

Settings → Special features → Game turbo mode

This will reduce ping by 5-15 ms due to prioritization of traffic.

8 Hardware solutions: antennas, repeaters and Mesh systems

If software methods are exhausted and the Internet is still slowing down, it’s time to consider hardware improvements:

• 📶 Install a repeater (repeater) Wi-Fi: Devices like Xiaomi Wi-Fi Repeater 2 (about 1,500) ₽) They amplify the signal in dead zones, optimal for large apartments or houses.
• 🔌 Use Powerline adapters: They transmit the Internet over wiring. TL-PA7010P (2 500 ₽) speeds up to 1 Gbps without loss.
• 📡 Upgrade your router to a Mesh system: Systems like Xiaomi Mesh System or ASUS ZenWiFi covers up to 500 m2 without any loss of speed.
• 📱 Buy an external antenna for Xiaomi: For models with an antenna connector (e.g. Xiaomi Mi) 10) can be connected to the antenna 4G/5G to enhance the mobile network signal.

The cost of hardware solutions varies from 1,000 to 20,000 ₽, But they are guaranteed to solve the problem of weak signal.

For owners of the Xiaomi 13/14 series with Wi-Fi 6E, it makes sense to consider routers with support for 6 GHz, such as the ASUS RT-AX89X or Netgear Nighthawk RAXE500. They provide speeds of up to 2 Gbps at short distances.

⚠️ Note: When using repeaters or Mesh systems, turn off Roaming (automatic switching between points) in the Wi-Fi settings on Xiaomi. In some firmware, it does not work correctly and leads to connection breaks.
