The situation when the smartphone Xiaomi or Redmi A device that refuses to connect to a wireless network often catches the user by surprise. Instead of the usual internet access, the device may endlessly try to obtain an IP address or simply return a connection error. This is a common problem that affects both old and new models, including the Mi, Poco And Redmi Note.
The reasons for this behavior can be completely different: from a simple router malfunction to a security settings conflict on the phone itself. Sometimes the culprit is a manually assigned static IP address, and sometimes it's a temporary glitch in a system module. AndroidUnderstanding the nature of a failure is half the battle to successfully resolving it without data loss.
In this guide, we will go into detail about all the possible scenarios why Xiaomi won't connect to Wi-Fi, and we'll offer step-by-step solutions. We'll cover both software aspects and hidden settings that are often overlooked by users during standard diagnostics.
Initial diagnostics and equipment reboot
Before delving into complex system settings, it's important to rule out simple hardware failures. Often, the problem lies not with the phone, but with the router itself, which may have frozen or exhausted the address pool for new connections. A simple router reboot often resolves the issue instantly.
If the router works reliably with other devices, it's worth checking the status of the Wi-Fi module in the smartphone itself. Enabling and disabling airplane mode helps force a reconnection to the tower or access point, resetting the current network settings. This action refreshes DHCP request and can fix the IP obtaining error.
⚠️ Attention: If you're using a dual-band router, make sure your phone is trying to connect to the correct frequency. Older models Xiaomi may not support the 5 GHz standard, preferring 2.4 GHz.
It's also worth checking whether the "Data Saver" or "Smart Wi-Fi" features are enabled, as they can block the connection if the system detects a weak signal. Disabling these options in the settings will force the module to operate normally, ignoring false signals about poor connection quality.
Resetting network settings on Xiaomi
One of the most effective methods when Xiaomi If your Wi-Fi connection fails, a complete network reset is recommended. This procedure deletes all saved passwords, Bluetooth, and mobile network settings, returning the network stack to its factory default state. This eliminates accumulated software conflicts.
To perform a reset, you need to go to the settings menu. The path usually looks like this: Settings → Connection and sharing → Reset Wi-Fi, mobile networks, and BluetoothAfter confirming the action, the phone will reboot and you will be required to re-enter the password for your wireless network.
☑️ Checklist before resetting the network
It's important to understand that this step doesn't delete your personal files, contacts, or apps. It only affects the network interface configuration. If the problem was caused by an incorrect system update or an error in the configuration files, this method should resolve the issue.
What to do if resetting doesn't help?
If the problem persists after resetting the network settings, it may be due to the antenna hardware or a deep system conflict that requires reflashing the device via a computer.
Problem getting IP address
A common situation is when the connection status changes to "Obtaining IP address..." followed by an error. This means that the router and phone "see" each other but cannot agree on a unique network identifier. This is often resolved by changing the IP type from static to dynamic.
To fix this, click on your network name in the list of available networks or select "Edit" on an existing network. In the "IP Settings" (or "IP Parameters") section, toggle the value from Static on DHCPThis will force the router to assign an address automatically.
In some cases, changing the device's MAC address can help. In Wi-Fi settings (often in advanced settings or when editing a network), you might find an option called "Privacy" or "Use randomized MAC address." Try switching this setting: if it's set to "Random," change it to "Device MAC address," and vice versa.
Date, time, and region settings
It might seem like an obvious setting, but an incorrect date and time can block connections to secure networks. Security protocols WPA2 And WPA3 Require time synchronization to verify certificates. If the phone's clock is slow or displays the wrong year, the connection will be terminated immediately after the authentication attempt.
Check if the "Use network time" option is set to automatic. You should also pay attention to the region. In some firmware versions MIUI or HyperOS Selecting the wrong region may limit the operation of certain frequency bands or encryption protocols.
| Parameter | Recommended value | Impact on Wi-Fi |
|---|---|---|
| Date and time | Automatic (network) | Critical for SSL/TLS certificates |
| Region | Russia / Country of residence | Determines available Wi-Fi channels |
| System language | Russian / English | Affects password encoding (rarely) |
| Time zone | Automatically | Log and security synchronization |
If automatic time setting isn't working, try temporarily setting the time manually, either ahead or behind by a few minutes, and then revert to automatic settings. This may "shake up" the system time services.
DNS and proxy server conflicts
Sometimes Xiaomi Connects to Wi-Fi, but the internet connection isn't working, or the connection is blocked during the test. This could be caused by incorrect DNS settings or an active proxy server previously configured for corporate networks or specific applications.
Check your proxy settings in the Wi-Fi menu. Click the gear next to your network, select "Proxy," and make sure it's set to "None." If there's an address listed there, delete it. For DNS, try using public servers, such as Google's (8.8.8.8) or Cloudflare (1.1.1.1), if the automatic ones can't cope.
⚠️ Attention: Using third-party DNS can speed up page loading, but in rare cases, some providers block access when changing DNS servers. If your internet connection is lost after changing DNS, return the settings to "Automatic."
It's also worth checking whether your browser or system has "Bandwidth Saver" enabled, which can redirect traffic through its own servers, blocking local connections. Disabling such features in your browser settings Chrome or system settings MIUI often returns access.
The influence of third-party applications and antiviruses
Installed internet speed booster apps, VPN clients, or aggressive antivirus programs can hijack control of the network adapter. This is especially true for apps that require root privileges or deep system access, which may remain after uninstallation or be running in the background.
Try starting your smartphone in safe mode. To do this, hold down the power button, and when the power icon appears on the screen, press and hold it for a few seconds. The system will prompt you to enter safe mode. If Wi-Fi works in this mode, the problem is with one of the installed apps.
Uninstall recently installed apps, especially those related to networking, memory cleaning, or interface changes. Also, check app permissions: sometimes messaging apps or games request network access and can cause conflicts if they don't function properly.
Hardware issues and router specifics
If software solutions don't help, it's worth considering hardware issues. The smartphone's internal antenna may have become disconnected after a fall, or the Wi-Fi module itself may have failed. Check that other wireless functions, such as Bluetooth or GPS, are working, as they often share the same antenna base.
On the router side, the problem could be an overcrowded client table. If you have a lot of smart devices at home, the router may simply not be able to issue new addresses. It's also worth checking the encryption type: some older models Xiaomi don't work well with encryption WPA3, preferring WPA2-PSK.
⚠️ Attention: Router interfaces and MIUI/HyperOS versions are constantly updated. If the menu items described here don't match your needs, look for similar names or consult the router manufacturer's documentation.
As a last resort, if all else fails, you can try resetting the router to factory settings. This will erase all custom settings, but it often fixes hidden firmware errors that prevent new devices from connecting.
Why does Xiaomi say "Authentication Error"?
This error most often means you entered the wrong password. However, if you're sure of the password, the issue may be with the encryption type on your router (try changing from WPA3 to WPA2) or with MAC address filtering enabled, blocking your phone.
How do I reset my network settings if the menu won't open?
If the system interface is frozen and does not allow you to enter settings, try entering a command in the engineering menu (if available) or perform a full reset of the device (Hard Reset) through Recovery Mode, but this will delete all data from the phone.
Can a system update break Wi-Fi?
Yes, sometimes after an update MIUI or HyperOS Driver conflicts may occur. In this case, clearing the Dalvik/ART partition cache via Recovery or waiting for a patch from the manufacturer to fix the issue may help.
