Why Xiaomi does not see Wi-Fi: all the reasons and ways to fix

You turned on Wi-Fi on Xiaomi, but the network doesn't show up on the list of available ones - or does the device not respond to connection attempts at all? This problem occurs on models from Redmi Note 10 to Xiaomi 14 Ultra, and there can be more than a dozen reasons: from a banal software failure to physical damage to the antenna. In 80% of cases, the malfunction is fixed on its own without going to the service center - the main thing is to correctly diagnose the source.

In this article, we will look at all the possible reasons why Xiaomi does not see Wi-Fi, from errors in router settings to hardware breakdowns. For each situation, we will provide step-by-step instructions with illustrations (where this is critical), warnings about typical user errors and proven solutions. We pay special attention to hidden settings MIUI, which the manufacturer does not advertise, but which often become the key to reconnecting.

If you have a Xiaomi smartphone, POCO or Redmi stopped seeing Wi-Fi after an upgrade, drop, or just "on its own" - start with the first partition. FAQ At the end of the article, where the most frequent questions are answered.

1. Check basic settings: router and smartphone

Before you dig deeper, rule out the obvious reasons. Start with the router: maybe the problem isn't the phone, but the signal sources.

• 🔄 Reboot the router. Turn it off for 30 seconds, then turn it back on. DHCP and temporary errors.
• 📶 Check the visibility of the network on other devices. If Wi-Fi does not see any gadget, the problem is the router or the provider.
• 🔒 Make sure the network is not hidden. In the router settings (usually 192.168.0.1 or 192.168.1.1), find the Hide option. SSID Or hide the network and turn it off.
• 📡 Change the channel. In urban settings, channels 1, 6 and 11 are often overloaded. Try manually selecting the channel (e.g., 3 or 9) in the router settings.

On the Xiaomi smartphone, do the following:

1. Open the Settings. → Wi-Fi and make sure the slider is on.
2. Slip on the three dots in the upper right corner and select Additional (or Wi-Fi settings).
3. Check if the Scan option is always available (in some firmware) MIUI It's off by default).
4. Turn it off. VPN (If you use it, some of them. VPN-Services are blocking local networks.

If you don't have a network after this manipulation, move on to the next section, and if Wi-Fi is visible but not connected (requests a password indefinitely or gives an authentication error), the problem lies in the router's security settings, read about this in the section on encryption protocols.

2. Network reset: when it helps

Resetting network settings on Xiaomi removes all stored Wi-Fi networks, Bluetooth devices and VPN-configuration, bringing back the communication settings to the factory settings, which helps in 60% of cases when the problem is caused by the problem:

• 🔧 Conflict. IP-Addresses (for example, if the router gives Xiaomi the same address) IP, as well as another device).
• 🔄 Cache failure DHCP or DNS.
• 📱 Errors in configuration files MIUI post-refresh.

How to perform the reset:

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

Make sure you remember your Wi-Fi passwords.

Save mobile internet data (APN)

Turn it off. SIM-card if you use mobile Internet

Write it down. MAC-device address (in case of linking to the router)-->

⚠️ Note: If you are using static IP (For example, to work with the corporate network, after the reset, you have to configure it again. → Wi-Fi → Additionally. → Advanced settings → Settings IP.

If the reset did not help, and the smartphone still does not see any network – the problem may lie in the hardware (antenna, Wi-Fi module) or deep settings. MIUI. We will talk about the last one in the next section.

3. encryption protocols and router security settings

One of the most common reasons Xiaomi doesn't see Wi-Fi is that encryption protocols are incompatible. WPA3, Many routers (especially older ones) use it by default. WPA2 or WEP. If the router settings are selected WPA2/WPA3 Mixed, this can also cause conflict.

How to check and correct:

To change the protocol:

1. Go to the router control panel (usually 192.168.0.1 or 192.168.1.1).
2. Find the Wireless Settings (or Wireless Network) section.
3. In the Security Mode (or Security Mode) field, select WPA2-Personal.
4. In the Encryption field (or Encryption) install AES (not TKIP!).
5. Save the settings and restart the router.

💡

If after changing the protocol Wi-Fi became visible, but the Internet does not work – check the settings DHCP Make sure that Automatic Receipt is enabled. IP (static).

If, even after these manipulations, Xiaomi persists in not seeing the network and other devices are connected normally, the problem may be regional settings of the router or smartphone.

4. Regional restrictions and frequency of broadcasting

Many people don’t know, but Xiaomi (and other brands) restricts the supported Wi-Fi frequency ranges depending on the region of sale.

• 🌍 Smartphones for China (China) ROM) don't support channels 12-14 ranged 2.4 GHz, which is often used in Europe.
• 🇪🇺 Models for the EU (EEA ROM) Can block 5.6 GHz channels (DFSC-regulation).
• 🇺🇸 Channels banned in the US 12-14 on 2.4 GHz, but high channels are allowed 5 GHz 165).

How this affects the connection:

• If the router is broadcasting on Channel 13 and your Xiaomi is running firmware for China, it simply won’t see the network.
• If you’re trying to connect to 5GHz, but your smartphone is limited to regional settings, the network will be unavailable.

Decisions:

1. Change the channel on the router to a universal one (for example, 1-11 for 2.4 GHz 36-48 for 5 GHz).
2. Check the regional settings of the smartphone: Go to Settings → Additionally. → Region: If China is, change to Russia or Europe (reset will be needed).

Update MIUI firmware

⚠️ Note: If you use custom firmware (like LineageOS or Pixel Experience), regional restrictions may be reset, in which case you will have to manually edit the build.prop file or install a patch to support all frequencies.

5. Software failures: drivers, MIUI and nucleus

If hardware problems and router settings are ruled out, the culprit could be the smartphone software.

5.1 Wi-Fi driver failure

After updating MIUI If you shut down the wireless module driver, it can go off:

• Wi-Fi is turned on but does not find any network.
• In Settings → The phone. → Version of the core appears errors.
• System Logs (Settings) → Special opportunities → Logs show errors like wlan: failed to load firmware.

Decisions:

1. Restart your smartphone in safe mode (press the power button). → Safe Mode Restarting? If Wi-Fi is triggered, a problem with a third-party app.
2. Clear the system cache: Settings → Memory. → Cleanup → Cash.
3. Reinstall the driver via Fastboot (for advanced users): fastboot flash wifi [name file driver.img] The driver file can be extracted from the official firmware for your model.

Conflict with MIUI Optimization

Function MIUI Optimization (optimization) MIUI) Sometimes it blocks background processes, including Wi-Fi scanning, to turn it off:

1. Activate Developer Mode (7 times tap the MIUI version in your phone settings).
2. Go to Settings → Additional → For developers.
3. Find the MIUI Optimization option and turn it off.
4. Reset the device.

💡

Shutdown MIUI Optimization can lead to increased battery consumption and changes in animations. Use this method only for diagnostics.

Damage to system files

If the smartphone does not see Wi-Fi after a failed update or manual intervention in system files, only flashing the firmware will help.

• 🔄 Update via Recovery (saves data).
• 📥 Clean installation via Fastboot (removes everything).

Instructions for both methods are available on the official Xiaomi website in the section MIUI Downloads. Choose firmware strictly for your model!

Hardware malfunctions: antenna, module and contacts

If all the software methods have been tried and Xiaomi still can't see Wi-Fi, it's the hardware.

How to diagnose a hardware problem:

1. Check Bluetooth. If it doesn't work, it's probably the combined module that's out of order. Wi-Fi/Bluetooth.
2. Check the body for dents or cracks (especially in the upper part where the antenna is located).
3. Try connecting to Wi-Fi in safe mode, and if there's no network, the problem is the hardware.
4. Use the test codes: ##4636## → Wi-Fi Information If the Wi-Fi Status section is empty or an error, the module is defective.

⚠️ Warning: Don't try to disassemble your smartphone to check the antenna yourself if you don't have experience! On Xiaomi models, the antenna is often glued to the middle bezel and connected to the board with thin plumes. Sloppy handling can exacerbate the problem.

Cost of repair in the service center:

• Replacement of Wi-Fi antenna: from 1,500 to 3,000 rubles.
• Module soldering Wi-Fi/Bluetooth: from 3 000 before 6 000 ruble.
• Replacement of motherboard: from 8 000 rubles (depending on the model).
