Are you trying to connect the Xiaomi Redmi Note 12, POCO X5 Pro or another smartphone brand to the home network, but the device stubbornly ignores Wi-Fi? Or the connection is constantly reset and the exclamation point is burning in the status bar? This problem occurs in one in five owners of Xiaomi - and the reasons can lie in both the phone settings and router parameters.
In this article, we’ll look at all possible scenarios, from commonplace errors (like a Wi-Fi module turned off) to deep MIUI firmware failures. You’ll learn how to diagnose a problem in 2 minutes, what router settings interfere with Xiaomi’s connection, and what to do if the phone “can’t see” only one particular network, and at the end, an FAQ with answers to frequent questions and a table of compatibility of Wi-Fi standards with Xiaomi models.
Basic checks: what to do first
Before you dig deep into the settings, rule out the obvious causes. In 60 percent of cases, the problem is solved at this stage.
- 📶 Make sure your phone is on Wi-Fi: swipe down from the top of the screen and check the Wi-Fi icon. If it's gray, tap it. On some models (such as the Xiaomi 13 Ultra), the module can turn off automatically in power saving mode.
- 🔄 Reboot router and phone: remove router plug from socket for 30 seconds, then turn back on. Smartphone reboot via menu or by pressing the power button.
- 🔍 Check the visibility of the network: if Xiaomi doesn't show your network on the list, but other devices see it, the problem is the phone. If no one can see it, the problem is the router.
- 🔐 Make sure you enter the correct password: MIUI If you have an incorrect password, there may not be an error, just an infinite “Getting” IP-Try to enter the password manually (sometimes autocomplete substitutes old data).
If Xiaomi still doesn’t connect after this, move on to the next section, and pay special attention to the reboot clause, which solves the problem 25% of the time, even if the device seems to be working fine.
2.Router-side issues: settings that block Xiaomi
Routers (especially budget models) often conflict with Xiaomi smartphones due to protocol incompatibility or aggressive security settings. This is what you need to check in the router admin panel (usually access at 192.168.0.1 or 192.168.1.1, login / password on the device sticker).
Network mode (2.4 GHz vs 5 GHz)
Xiaomi may not connect to a 5GHz network if:
- 📡 The router is running 802.11ac (Wi-Fi 5), The phone only supports the 802.11a/n (It is very important for older models like Redmi. 4X).
- 🔄 Smart Connect is enabled, which automatically throws devices between frequencies – sometimes it knocks Xiaomi down.
- 🚫 The router's settings are off. WMM (Wi-Fi Multimedia – without it, some phones can’t connect to 5GHz.
Decision:
- Go to the router settings → Wireless mode (Wi-Fi) → 5 GHz settings.
- Set 802.11a/n/ac (or 802.11n/ac for new models).
- Turn off Smart Connect and give the networks 2.4 and 5 GHz different names (for example, MyWiFi_2G and MyWiFi_5G).
- Enable WMM (usually in the Additional Wi-Fi settings section).
Type of encryption and security
Xiaomi can ignore networks with:
- 🔒 Outdated encryption WEP or TKIP (Use only WPA2-PSK or WPA3-PSK).
- 🛡️ The enabled function "Filtration" MAC-addresses” (if MAC Xiaomi is not on the white list).
- 🔄 Dynamic. DHCP, non-issuer IP-Address (check if the server is on) DHCP router-setting).
Set up encryption. WPA2-PSK (AES)|Turn off the filtering. MAC-address|Enable the server DHCP|Turn off customer isolation (AP Isolation)|Check that the channel is not overloaded (use channels 1, 6 or 11 for 2.4 GHz)
-->
How to check MAC-Xiaomi:
Go to Settings. → The phone. → General information → Status, look for a line. MAC-Wi-Fi address (e.g. 00:11:22:33:44:55) This address should be added to the whitelist on the router if filtering is enabled.
Overloaded channels and interference
If the router runs on a noisy channel (especially in apartment buildings), Xiaomi can connect, but the connection will be unstable or absent. Use applications like WiFi Analyzer (available on Google Play) to find a free channel.
| Range. | Recommended channels | Note |
|---|---|---|
| 2.4 GHz | 1, 6, 11 | They do not cross with neighboring channels. |
| 5 GHz | 36, 40, 44, 48, 149, 153, 157, 161 | In Russia, channels 36-64 and 149-165 are allowed |
💡
If you have a dual-band router, try connecting Xiaomi to a 2.4GHz network – it has a longer range and passes through walls better.
3.Changes in Xiaomi settings: from MIUI to hardware failures
If the router is set up correctly, but Xiaomi is still not connecting, the reason may lie in the phone itself.
3.1. Resetting network settings
MIUI sometimes gets the connection settings down to reset them.
- Go to Settings. → SIM-maps and mobile networks → Resetting network settings.
- Confirm the action (you may need to enter a pattern lock or PIN-code).
- Restart your phone and try to connect again.
⚠️ Warning: This reset will remove all saved Wi-Fi networks, passwords and settings VPN. Data data SIM-map (APN) They will also be thrown to the factory.
Error “Receiving” IP-addresses" or "authentication»
If Xiaomi is stuck in the IP or authentication phase:
- 🔄 Forget the network: go to Settings → Wi-Fi, tap on the problem network → Delete (or forget). Then connect again.
- 📱 Turn on/off the plane mode for 10 seconds – it will reset the network modules.
- 🔧 Set up static. IP: In the Wi-Fi settings tap on the network → Change the network → Additional. In the Settings field. IP Select Static. Specify. IP-address from the range of your router (e.g. 192.168.0.100 if router 192.168.0.1). DNS — router address (e.g. 192.168.0.1).
