When a Xiaomi smartphone stops seeing the home network or hangs indefinitely in Connection status, it can happen suddenly: you just take the device to check your email and the Wi-Fi icon is crossed out or flashed. Often the problem is not the failure of the device itself, but a software failure of the MIUI or HyperOS firmware, or a conflict of router settings.
Before you bring a gadget to a service center, you need to do a series of diagnostics that bring the module back to life 90 percent of the time, and it's important to understand that the wireless module is a sensitive component that responds to changes in software and energy saving, sometimes a simple reboot is enough, and sometimes a deeper intervention in system files is required.
In this article, we will discuss all the current ways to restore connection, from simple actions to advanced methods for power users. You will learn how to reset network settings correctly, why you should not ignore system updates and when the problem lies in the hardware of the device. Follow the instructions consistently to avoid unnecessary actions.
Basic diagnostics and reboot of the module
The first step is always to check the hardware, and often Android accumulates temporary errors that block the network interfaces. Try to turn on and off flight mode. To do this, swipe the notification curtain down and find the aircraft icon. Activate it, wait 10-15 seconds and turn it off. This action will force all radios to restart, including GSM and Bluetooth.
If that doesn't work, reboot your smartphone completely. Don't just turn off the screen, use the off menu. Some versions of the MIUI require you to press the power button for a few seconds. Once you turn on, give the phone 2-3 minutes to fully initialize all services before trying to connect.
⚠️ Warning: If the Wi-Fi icon has disappeared from the curtain or has become gray and inactive after the reboot, this may indicate a serious system failure or a module board dump.
It's also worth checking if the Internet is working on other devices. Connect your laptop or tablet to the same access point. If no device can see the network, the problem is definitely not the Xiaomi phone, but the router or provider. Make sure that the router is on the appropriate activity indicators.
Checking the settings of date, time and region
One of the most common and non-obvious reasons for a failure is to desynchronize system time. Security protocols WPA2 and WPA3 are critically dependent on the exact time. If the date on the phone is lost several years ago or forward, the router's security certificates will be invalidated and the connection will break.
Go to your device settings and find the "Advanced" or "System" section. Make sure you check the "Use Network Time" box. If it's already up, try removing it, manually setting the wrong date, save it, and then turn on automatic synchronization again, which will update the time stamps in the system.
Another important parameter for Xiaomi devices is region. Some models in certain regions have frequency band limits. Go to Settings → Additional settings → Region. Try changing country to China or Singapore, then restart your phone and check Wi-Fi. After checking, return your region back.
💡
Changing the region to China will sometimes unlock hidden features and change the list of available Wi-Fi channels, which helps in difficult connection cases.
Resetting network settings and removing profiles
If simple methods fail, you need to clear up the accumulated errors in network configurations. Your phone stores data on all networks ever connected, and sometimes that data gets corrupted. Go to the Wi-Fi menu, click on your network name, and select "Delete" or "Forget."
A more radical but effective method is to completely reset your network settings. This action will delete all stored Wi-Fi passwords, Bluetooth and mobile network settings, but will not affect your personal files, photos or contacts. The path to the feature may vary depending on the Android version, but it is usually here: Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth.
☑️ Checklist before resetting network settings
Once the reset is done, the phone will reboot, you will need to re-enter the password from the home network. IP-address DHCP, The connection has to be restored. In some cases, manually mounting a static connection helps. IP-Addresses in the extended connection settings.
Working with frequency bands and router
Modern routers work in two bands: 2.4 GHz and 5 GHz. Older Xiaomi smartphones or devices with cheap modules can not work properly with the 5 GHz channel, especially if it is congested with neighbors. Try to log into the router settings (usually at 192.168.0.1 or 192.168.1.1) and divide the network names (SSID) for the two bands.
Connect your phone to a 2.4 GHz network. This range has a lower speed, but it breaks through walls much better and has greater compatibility. Also, in the router settings, it is worth checking the type of encryption. For maximum compatibility, it is recommended to use AES. If you need TKIP or mixed mode, the phone may refuse to connect.
| Parameter | Recommended value | The impact on Xiaomi |
|---|---|---|
| Channel (2.4 GHz) | 1, 6 or 11 | Reduces interference from neighbouring routers |
| Channel width | 20 MHz | Increases stability, reduces speed |
| Protocol | 802.11 n/g/b | Basic compatibility for all devices |
| Encryption | WPA2-PSK (AES) | Optimal safety and speed |
If you have a dual-band router, make sure the "Smart Connect" feature is turned off. Xiaomi smartphones sometimes get "stuck" when switching between ranges if the network names are the same.

Update the system and reset to factory settings
Xiaomi regularly releases security updates, which often contain patches to fix Wi-Fi driver errors. Go to Settings → About the phone and check for updates. If a new version of MIUI or HyperOS is available, be sure to install it.
If the problem appeared immediately after the update, the situation is reversed: the new firmware may contain a bug, which will help to wait for the next patch or, for advanced users, rollback to the previous version via Recovery mode. However, if the phone does not connect to the network at all, you can only update through the computer using the Mi Flash Tool utility.
The cardinal solution is a complete reset to the factory settings (Hard Reset).This will delete all data from the phone, so make sure to back up. Way: Settings → Phone → Reset → Erase all data. After this procedure, the phone will become like new, and if the problem was software, it will disappear.
⚠️ Warning: Before a full reset, make sure you remember the password from your Mi Account. Once turned on, the phone will require it to prove ownership (protection against theft).
Hardware problems and module repair
If none of the software methods worked, there is a high probability of physical malfunction. The antenna module in Xiaomi smartphones is often integrated into the bottom board or charging plume. If the phone fell, fell into the water or was simply in use for a long time, the antenna contact with the motherboard could be disrupted.
It can also cause the Wi-Fi chip itself to fail, often after power surges when charging with substandard power supplies or when the device overheats during games, and hardware breakdowns: a grey Wi-Fi icon, no network search even near the router, fast battery discharge in network search mode.
You can use an engineering menu to diagnose this. Type ##6484## in the dialer. Select CIT or Wireless, then Wi-Fi. Run the test. If the system comes up with an error or the test freezes during the scanning phase, this is a direct route to the service center.
💡
If the Wi-Fi module does not pass the test, the software reset is useless - you need to replace the antenna plume or soldering the chip.
