Wi-Fi on Xiaomi does not work: all the reasons and ways to fix

Wi-Fi connectivity issues on Xiaomi smartphones are one of the most common complaints users have received. According to service center statistics, up to 30 percent of calls over the network are due to unstable or absent wireless connections, and the problem is equally common on low-end Redmis and Mi or Poco flagships. Most of the time, it is not hardware malfunctions that are to blame, but software failures or incorrect settings — and that’s good news, because such problems can be fixed on their own.

In this article, we’ll look at all the possible reasons why Wi-Fi doesn’t work on a Xiaomi phone, from simple password errors to complex system conflicts, how to diagnose a problem, which settings to check first, and when to actually contact the service. We will pay special attention to the unique "chips" of firmware MIUI, which often become a source of network problems (for example, hidden background restrictions or conflicts with the function "Dual applications").

1. Checking the basic parameters: router and phone

Before digging deep into your smartphone settings, make sure the problem isn't on the router or ISP's side.

• 🔌 Reset the router. Turn it off for 30 seconds, then turn it back on. DNS and temporary errors.
• 📶 Check the signal on other devices. If Wi-Fi doesn't work on both your laptop and your tablet, the problem is with the router or the ISP.
• 🔒 Make sure you enter the correct password. MIUI if the password is incorrect, the error "Connection..." may appear without clarification.
• 🌐 If the phone sees neighboring networks but does not connect to yours, the problem is local (for example, the problem is not connected to yours, MAC-router-filter).

If other devices are connected normally and Xiaomi is not, go to the phone settings. Start by turning on/off the aircraft mode (Settings) → SIM-maps and mobile networks → Airplane mode. This resets all network modules, including Wi-Fi.

⚠️ Note: Some Xiaomi models (e.g. Redmi Note 10 Pro) after upgrading to MIUI 14 there is a bug with a "perpetual connection" to Wi-Fi. In this case, only resetting network settings will help (more about this below).

2. Network Resetting: When and How to Do

If the basics don't work, the next step is to reset the network settings, which removes all stored Wi-Fi networks, Bluetooth devices and other devices. VPN-configuration, but does not affect personal data:

1. Go to Settings → Memory and smartphone → Reset settings.
2. Select Network Resetting.
3. Confirm the action (you will need to enter a pattern lock or PIN).
4. After restarting, try connecting to Wi-Fi again.

On models with MIUI 13+, the path may differ: Settings → Additional → Recovery and Reset → Network Reset. Once reset, the phone will automatically restart.

If the reset doesn’t help, check if the “Adaptive Wi-Fi” function is activated (Settings) → Wi-Fi → Additionally. → Adaptive Wi-Fi: This option automatically switches your phone to mobile Internet when you have a weak Wi-Fi signal, but sometimes it doesn't work properly. Try turning it off.

3. Conflicts with MIUI firmware: hidden settings and bugs

MIUI is known for its features, which sometimes break the standard network operation, and these are the most common problems.

• 🔄 Automatic switching to mobile data. → SIM-maps and mobile networks → Switch to mobile data, disable this option.
• 📱 Dual apps. If you cloned messengers (like WhatsApp), they can block access to the network. → Annexes → Dual annexes.
• 🔒 Background restrictions: Some applications (such as file downloaders) can block Wi-Fi in the background. → Annexes → Permits → Autostart and enable autostart for system services.
• 🛠️ Developer Mode. If you've activated it before, check the settings in Settings. → The phone. → Version. MIUI (7 times tap to turn on. Then in Settings → Additionally. → For developers, turn off adaptive brightness Wi-Fi.

On the Poco F3/F4 and Redmi K40/K50 models, Wi-Fi may disappear after upgrading to MIUI 14 due to a conflict with the wlan module. In this case, only a firmware rollback or manual firmware through the Fastboot will help.

4.Iron problems: antenna, Wi-Fi module and repair

If the software methods didn't work, it might be the hardware, and here are the signs that the problem is physical:

• 📉 The phone doesn’t see any network (even public ones).
• 🔍 Signal disappears when the phone is tilted (an antenna may be damaged).
• 🔥 Overheating in the upper part of the body (possibly damaged Wi-Fi module).
• 💥 The problem arose after falling or getting moisture.

In these cases, self-repair is impossible – you need a diagnosis in the service center. The average cost of replacing a Wi-Fi module on Xiaomi is from 1500 to 3500 rubles (depending on the model). On Redmi Note and Poco, the module is often combined with a Bluetooth module, so change them together.

⚠️ Attention: On Xiaomi Mi 10T mi 11T The Wi-Fi antenna is integrated into the metal frame of the body, and if the frame is damaged (for example, after a blow), the signal may disappear, in which case the entire average frames are replaced, which is more expensive than standard repairs.

If your phone has recently been repaired (for example, changed the screen or battery), check if the antenna plume is damaged. On the Redmi Note 9 Pro and Poco X3 NFC, it passes next to the charging connector and can be affected by careless disassembly.

5. Conflicts with VPN, proxy and firewall

VPN applications, proxy servers, or even the built-in MIUI firewall can block access to Wi-Fi. Check the following:

1. Turn off the VPN. Go to Settings → Connections & Sharing → VPN and deactivate all connections.
2. Check the proxy. In Settings → Wi-Fi → [your network] → Change the network → Additional → Proxy should stand for No.
3. Turn off the firewall. MIUI has a hidden firewall: Settings → Applications → Permissions Management → Firewall.
4. Delete suspicious applications. Some Internet "optimizers" or "accelerators" (such as the DU Speed Booster) can break the network.

If you use corporate Wi-Fi with certificates, remove them to Settings → Security → Trusted credentials. Sometimes outdated certificates conflict with new network settings.

💡

If you frequently connect to public Wi-Fi (at cafes, airports), disable the Auto Connection function in the Wi-Fi settings.

6. Update firmware and roll back to stable version

Firmware errors are one of the main causes of Wi-Fi problems on Xiaomi. For example, MIUI 13.0.4 for the Redmi Note 10 had a bug that caused the phone to lose network after 5 minutes of inactivity, in which case an update or rollback helps:

• 🔄 Update the system. Go to Settings. → Update and check for updates. If the update weighs more than 500MB, it's likely a major bug fix.
• 📉 If the problem occurs after the update, you can return the old firmware via Fastboot (instruction below).
• 🛠️ Install custom firmware. For example, Pixel Experience or LineageOS often work better with the network than stock. MIUI.

How to roll back through Fastboot:

1. Download stable firmware from https://new.c.mi.com/global/miuidownload/index


2 Unpack the archive and place the file in the folder with ADB.




3. Connect your phone to your PC in Fastboot mode (clip Volume Down + Power).




Enter the command:




fastboot flash recovery recovery.img




fastboot flash boot boot.img




fastboot flash system system.img




5.Reboot phone: fastboot reboot

⚠️ Attention: Firmware rollback erases all data from the phone! pre-backup through Settings → Additionally. → Backup and reset.

💡

If Wi-Fi is gone after the upgrade and rollback is not helping, check if Find Device is activated, and in some cases, it blocks network modules after the reset.

7. Alternative ways of connecting to the Internet

If Wi-Fi on Xiaomi has not worked, you can use alternative methods of connection:

• 📶 Mobile Internet. Activate data transfer to Settings → SIM-maps and mobile networks → Mobile Internet.
• 🔗 USB-Connect the phone to the PC via modem. USB and turn on USB-modem-curtained notification.
• 📡 Access point from another device. Spread the Internet from a second phone or tablet.
• 🌐 Ethernet via adapter. OTG (for example, Poco F3) You can use a USB-Ethernet adapter.

On Xiaomi Mi 10 and later, there is a Wi-Fi Direct feature that allows you to connect to other devices without a router. It is activated in Settings → Connections and Sharing → Wi-Fi Direct.

If you need internet urgently and Wi-Fi is not working, try turning on the modem on another phone and connect to it via Bluetooth. The speed will be lower, but for instant messengers or mail, this will be enough.
