Why Xiaomi Redmi is missing Wi-Fi: a full analysis of the causes and solutions

You're sitting with a Xiaomi Redmi phone, watching a video or playing an online game, and suddenly the Internet goes down, the Wi-Fi icon is gray, the connection is severed, and after a couple of seconds (or minutes) everything miraculously recovers, or does not recover at all. This problem is haunting the owners of the Redmi Note. 9/10/11, POCO X3/X4 and other models based on MIUI. Why it happens and how to fix it once and for all?

V 80% And it's not the hardware that's to blame, but the software, from firmware bugs to router conflicts, but there are hardware reasons, like the wear and tear of the Wi-Fi module after it's gone. 2-3 In years of heavy use (especially for low-cost Redmi models with passive cooling), we will look at all possible scenarios, from banal failure of settings to hidden defects in the board. And we will give checklists for diagnosis and step-by-step instructions that work even if you have never dug into the settings of the smartphone.

Spoiler: Half the time, a simple router reboot helps, but if the problem comes back, you have to act systematically, start with the obvious and end up with things that are not written about even in service centers.

Router problems: why the phone is "losing" the network

The first thing to check is whether your router is to blame for the lost Wi-Fi. 9A/9C) If the router is giving a weak signal, uses an overloaded channel or an outdated security protocol, the phone will constantly fall off".

How to know if the problem is in the router:

• 📶 Other devices (laptop, tablet) also lose communication with the same network.
• 🔄 Wi-Fi only disappears in a certain room (the signal does not reach the phone).
• 🔒 In the settings of the router is enabled mode 802.11r (Fast Transition – It is in conflict with MIUI.
• ⚡ The router overheats or automatically reboots (blinks all indicators).

What to do:

1. Restart the router (pull the plug out of the socket for 30 seconds).
2. Change the Wi-Fi channel in the router settings (preferably choose 6 or 11 for 2.4 GHz).
3. Disable Band Steering (if any) – it forcibly switches devices between 2.4 and 5 GHz, which Redmi doesn’t always handle correctly.
4. Update the router firmware (relevant to TP-Link, Keenetic, ASUS).

⚠️ Note: If you have a dual-band router, try connecting to only 5GHz (or vice versa, only 2.4GHz).Some Redmi models don't work well in Smart Connect mode when the router chooses the range itself.

2.Firmware failures MIUI: Bugs that break Wi-Fi

MIUI — It's not just an Android shell, it's an ecosystem with bugs of its own. MIUI 12.5 and MIUI 13, where users complained en masse about Wi-Fi issues. For example, there was a bug in the Redmi Note 10 Pro that caused the phone to disconnect from the network when the screen was locked. POCO X3 NFC — Problem with autoconnection after sleep.

How to check if the firmware is to blame:

• 🔍 Go to Settings. → The phone. → Version. MIUI Check the relevance of the updates.
• 📱 Check out the reviews on the forums (for example, 4PDA Mi Community – your model may be on the list of “problems".
• 🛠️ If there are no updates, but there is a problem, try resetting your network settings (Settings) → Wi-Fi → Additionally. → Resetting network settings).

What to do if the bug in the firmware:

Update the firmware to the latest version

Clear the system cache (Settings) → Memory. → Clear the cache)

Disable Adaptive Communication in Wi-Fi settings

Reset your network settings (not to be confused with a full reset!)

Install custom recovery (for example, TWRP) and patch for Wi-Fi (for advanced users only)-->

If the problem persists after the update, try to roll back to the previous version of MIUI.

1. Download the firmware archive from miuirom.org.
2. Rename the file to update.zip and place it in the root of the phone’s memory.
3. Go to Settings. → The phone. → Update system, click on three dots at the top → Select a firmware file.

⚠️ Attention: Firmware rollback may cause data loss.Pre-backup through Settings → Additionally. → Backup and reset.

3. Conflict with energy saving settings

Xiaomi aggressively optimizes power consumption, and sometimes it harms the stability of Wi-Fi. For example, the Adaptive Battery feature can force network connections to be turned off in the background, and Background Limitation can block application updates over Wi-Fi.

How to check:

• 🔋 Go to Settings. → Battery and productivity → Battery settings.
• 📴 See if the Power Saving or Super Energy Saving mode is enabled.
• 🔄 Check if Wi-Fi is turned off when the screen is locked (turn on the option to Keep Wi-Fi active in Wi-Fi settings).

What to do:

If nothing works, try turning off all the power saving features for your Wi-Fi network:

1. Go to Settings. → Wi-Fi.
2. Click on your network. → Change the network.
3. Enable the option to Connect automatically and Support the connection.
4. Turn off Data Use Restriction (if enabled).

💡

If you have a Redmi Note 8 Pro or older, try turning off the dual connection (Wi-Fi) feature. + It often conflicts with energy conservation and leads to communication breakdowns.

Hardware malfunctions: when the "iron" is to blame

If the software methods didn't work, maybe the problem is with the phone's Wi-Fi module itself.

• 📱 Older phones. 2-3 years (natural wear of contacts).
• 💥 Devices that have fallen or been exposed to moisture (even if everything is externally intact).
• 🔥 Overheated models (e.g, POCO X3 playful).

Signs of hardware malfunction:

• 📶 Wi-Fi disappears even near the router (100 signal%).
• 🔌 The phone doesn’t see a network (or sees but doesn’t connect).
• 🔧 After the reboot, Wi-Fi is working. 5-10 minutes, then disappears again.
• 🛠️ The service menu (#4636##) shows the error Wi-Fi status: Error.

What you can do on your own:

1. Check if there is moisture under the back cover (especially if the phone is not waterproof).
2. Carefully tap on the back panel in the Wi-Fi antenna area (sometimes helps with poor contact).
3. Try connecting to Wi-Fi in safe mode (hold the power button) → Safe Mode. If it works, it's the software, not the hardware.

⚠️ Warning: If your phone falls or gets wet, don't try to disassemble it yourself, you risk damaging the plumes. In this case, the only way out is a service center — 1500-3000 ruble.

5. Conflict with VPN, firewall or antivirus

Sometimes Wi-Fi is lost not because of problems with the module itself, but because of a conflict with the installed applications.

• 🔒 VPN-clients (NordVPN, ProtonVPN, 1.1.1.1).
• 🛡️ Antiviruses (Avast, Kaspersky, 360 Security).
• 📡 Applications for Internet Speed Master (NetOptimizer).
• 🔄 Battery optimizers (DU Battery Saver, Greenify).

How to diagnose:

1. Go to Settings → Applications → Application Management.
2. Sort the applications by installation date – it is possible that the problem appeared after installing the new software.
3. Try to turn it off. VPN or antivirus 10-15 Check the stability of Wi-Fi.

What to do:

• 🚫 Remove suspicious apps (especially if they have requested permission to change network settings).
• 🔄 Reset network settings (Settings) → Wi-Fi → Additionally. → Resetting network settings).
• 🛠️ If you use VPN, Try changing the protocol (for example, from OpenVPN to WireGuard).

Example: Redmi Note 9 Pro had a bug when Kaspersky Internet Security blocked connection to some TP-Link routers, which was solved by disabling the Network Screen function in the antivirus settings.

6. Incorrect settings IP and DNS

If your Redmi is getting incorrect IP-address or uses "broken" DNS-And the problem is that the servers, the Wi-Fi, will be constantly breaking, and this is especially true for corporate networks or routers with custom settings.

How to check:

• 📊 Go to Settings. → Wi-Fi → Your network. → Change the network → Additionally.
• 🔢 Look at the kind of IP-Address assigned by phone (should be in range) 192.168.x.x or 10.x.x.x).
• 🌐 Check it out. DNS — If there are strange values (for example, 0.0.0.0), they should be reset.

What to do:

1. Reset the settings. IP Automatic Receipt: Settings → Wi-Fi → Your network. → Change the network → Additionally. → Settings IP → DHCP
2. Change it. DNS Public (e.g. Google or Cloudflare): Settings → Wi-Fi → Your network. → Change the network → Additionally. → DNS → Manually Enter: 8.8.8.8 and 8.8.4.4 (Google) or 1.1.1.1 and 1.0.0.1 (Cloudflare)
3. If you are using static IP, Make sure it doesn’t conflict with other devices on the network.

⚠️ Attention: If after the shift DNS Wi-Fi has become more stable, the problem was in the provider, and some Russian operators (for example, Rostelecom or MTS) use “curves" DNS, conflicting MIUI.

💡

After the shift DNS Internet speeds increased, and the cliffs became smaller – the problem was in the settings of the network, not the phone.

7. Phone overheating: why Wi-Fi shuts down when loaded

Many Redmi models, especially POCO X3, Redmi Note 10 Pro) suffer from overheating under prolonged load when the processor temperature exceeds 60-65°C, the system begins trottling - a forced performance restriction that can affect the Wi-Fi module.

How to check:

• 🌡️ Install the app AIDA64 or CPU Monitor and look at the temperature of the processor.
• 🔥 If the phone is hot to the touch (especially at the top) the protection is likely to work.
• 🎮 Is the problem manifested during games or charging? is it a classic sign of trottling.

What to do:

• 🧊 Remove the cover (it worsens the heat sink).
• 🔋 Do not use your phone while charging (or switch to slow charging) 5W).
• 🛠️ Turn off background processes (Settings) → Annexes → Application management → Clear it all up).
• 🔄 If you play, reduce the graphical settings in the game (for example, in the game). PUBG Mobile or Genshin Impact).

For advanced users:

1. Install a custom core (e.g., FrancoKernel) with improved temperature control.


2. Disable part of the processor cores in the engineering menu (#4636## → CPU).




3. Use a cooling stand (relevant to gamers).
