You are trying to connect to a wireless network, but Xiaomi Redmi Note It stubbornly ignores your attempts: the Wi-Fi button is inactive, the indicator light is off, and the list of networks is empty or displays the error "Unable to turn on." Sound familiar? Wi-Fi issues on smartphones of this series are more common than expected, but in 90% of cases, they can be resolved without a service center visit.
In this article we will look at all possible reasons — from trivial software glitches to antenna hardware malfunctions. You'll learn how to distinguish software glitch (which is treated by rebooting or resetting) from physical damage (needs repair), and also receive step-by-step instructions for every situation. We will pay special attention to models Redmi Note 10/11/12 and their specific "diseases" associated with MIUI updates.
Before you panic, check: the problem might lie not with your phone, but with your router or network settings. For example, if Wi-Fi doesn't turn on in only one place (at home or work), but works in a cafe, it's more likely the router, not your phone, is to blame. Let's start with the most basic diagnostics.
1. Basic checks: router, airplane mode, and reboot
Start with the obvious—sometimes a problem can be solved in 30 seconds. The first thing you need to do is: make sure Wi-Fi is working on other devicesConnect your laptop, tablet, or second phone to the same network. If there's no internet connection anywhere, the router is to blame (reboot it and check your internet service provider's bill). If Wi-Fi only works on some devices, the problem is in the settings. Redmi Note.
Next, check:
- 📱 Airplane modeEven if the indicator light isn't on, swipe down the notification panel and make sure the mode is disabled. Sometimes it's activated accidentally (for example, when removing the SIM card).
- 🔄 Restart your phone: Press and hold the power button and select "Restart." This will clear any temporary Wi-Fi issues.
- 📶 Geolocation and mobile data: In some regions (such as China), Wi-Fi requires location services to be enabled. Try enabling them in
Settings → Privacy → Permissions → Location.
If Wi-Fi still doesn't work after rebooting, proceed to the next step. But first, answer this question:
Important! On models Redmi Note 10 Pro and newer after updating to MIUI 14 The "Wi-Fi" option in the notification bar may disappear. This isn't a bug, but a UI issue. To restore the button, swipe down twice (a full swipe)—all hidden elements will be displayed.
2. Reset network settings: when the phone “forgets” Wi-Fi
If Wi-Fi turns on but doesn't connect to the network (or constantly asks for a password), the culprit is corrupted network settingsThis happens after:
- 🔄 MIUI updates (especially with MIUI 12.5 on MIUI 13/14).
- 📱 Installing custom firmware or rooting.
- ⚡ Power surges (if the phone was discharged to zero).
To reset network settings:
- Go to
Settings → Connections and Sharing → Reset Wi-Fi, mobile network, and Bluetooth settings. - Confirm the action (you will be asked to enter your pattern or PIN).
- Restart your phone.
☑️ What to do after resetting the settings
Warning! Resetting your router will delete all saved Wi-Fi networks and their passwords. If you don't remember your home network password, look it up on another device or on a sticker on the router.
If a reset doesn't help, the problem may lie deeper—in the Wi-Fi module drivers or the firmware itself. We'll discuss this further.
3. Firmware Issues: MIUI Bugs and How to Fix Them
Xiaomi known for its frequent updates MIUI, but not all of them go smoothly. For example, after the release MIUI 13 many users Redmi Note 9/10 faced with the fact that Wi-Fi turns on, but doesn't pick up any network or constantly disconnects. The culprits are:
- 🐛 Bugs in the system kernel (especially in versions for the global market).
- 📦 Conflict with Google Play Services (if the phone is of Chinese assembly).
- 🔧 Incorrect power saving settings (MIUI aggressively disables background processes).
How to fix:
- Update MIUI to the latest version:
Settings → About phone → System updateIf the update does not arrive automatically, check for it manually. Redmi Note 11 and newer weekly patches are available.
- Disable Wi-Fi optimization in power saving mode:
Settings → Battery & performance → Power saving mode → Settings → Disable "Wi-Fi optimization" - Reset MIUI to factory settings (if other methods did not help):
Settings → Advanced → Backup & reset → Factory data reset⚠️ Attention! A hard reset will delete all data from your phone. Make a backup beforehand.
Settings → About phone → Backup.
What to do if updating MIUI doesn't help?
If Wi-Fi still doesn't work after updating, try rolling back to the previous firmware version. To do this:
1. Download the archive with the required MIUI version for your model from the website en.miui.com.
2. Rename the file to update.zip and place it in the root folder of your phone.
3. Go to Settings → About phone → System update → Three dots (menu) → Select firmware file.
4. Confirm the rollback.
Important! Downgrading is only possible within a single MIUI branch (e.g., from 14.0.5 to 14.0.3). Downgrading to an older version (e.g., from 14 to 13) requires unlocking the bootloader and may brick the phone.4. Hardware problems: how to test the Wi-Fi module
If software methods do not work, the problem may be in physical damage:
- 📡 The Wi-Fi antenna is damaged (for example, after a fall or exposure to moisture).
- 🔌 The Wi-Fi/Bluetooth module cable has come loose (a common problem after disassembling the phone).
- ⚡ The module itself has failed (rare, but it happens when it overheats).
How to diagnose a hardware failure:
- Check Bluetooth operation: if it also does not turn on, the problem is definitely in the module (Wi-Fi and Bluetooth in Redmi Note use one chip).
- Use the engineering menu:
##4636##Go to the "Wi-Fi Information" section and check the module's status. If it's blank or says "Error," the chip is faulty.
- Check your phone for moisture: Even if you didn't drop it in water, condensation could have damaged the contacts. Please note moisture indicator (small white dot in the SIM card slot - if it is red, there was moisture).
Critical information: On the Redmi Note 8/9/10 models, the Wi-Fi module is located next to the battery. If the phone is dropped on a corner (especially the lower right corner), both the antenna and the chip itself may be damaged. In this case, repairs are only possible at a service center.
| Symptom | Probable cause | Solution |
|---|---|---|
| Wi-Fi doesn't turn on, the button is gray | MIUI software glitch or bug | Reset network settings or roll back firmware |
| Wi-Fi turns on but doesn't find any networks. | The antenna or cable is damaged | Diagnostics in service |
| Wi-Fi works, but it keeps disconnecting. | Conflict with energy conservation | Disable Wi-Fi optimization in battery settings |
| Wi-Fi and Bluetooth don't work at the same time | The combination module is faulty | Replacement of the module in the service center |
5. Application conflicts: what's stopping Wi-Fi from working?

- 🛡️ Block network traffic (antiviruses, VPN, firewalls).
- 🔄 Intercept network control (Internet speed-up applications).
- 📱 Use non-standard proxy settings (for example, some Chinese applications).
How to find the culprit:
- Start your phone in safe mode (Press and hold the power button → long tap "Power Off" → "Safe Mode"). Only system apps work in this mode. If Wi-Fi works, one of your installed apps is to blame.
- Check app permissions:
Settings → Apps → Manage apps → Three dots (menu) → App permissions → Location/NetworkRevoke network access from suspicious programs.
- Uninstall recently installed applications (especially optimizers, VPNs, and Chinese utilities).
The most problematic applications For Redmi Note:
- 🔍 Clean Master, DU Speed Booster — aggressively optimize background processes, including Wi-Fi.
- 🌐 1.1.1.1 (Cloudflare), Psiphon — may conflict with DNS settings.
