The situation when the smartphone Xiaomi A wireless network that stops detecting or shows an unstable connection can be frustrating for any user. We're used to having the internet at our fingertips, and a sudden loss of connection disrupts work, communication, or leisure. More often than not, the problem stems not from hardware failure, but from a software glitch or incorrect router settings.
Owners of devices based on Android Often, people encounter situations where their phone sees neighboring networks but ignores their home network, or the connection constantly drops. This can be due to the list of saved networks being full, IP address conflicts, or system power-saving features. MIUIUnderstanding the nature of the error is the first step to successfully eliminating it.
In this article we will take a detailed look at all the possible reasons why Xiaomi If your device is having trouble getting a signal, we'll offer step-by-step instructions for restoring the communication module's functionality. You won't need any advanced programming knowledge; just follow the instructions. We'll cover everything from simple methods like rebooting to more complex manipulations of system files.
Basic diagnostics and software failures
Before delving into the intricacies of settings, it's important to rule out basic software errors. The operating system, like any complex software, occasionally accumulates temporary files that can cause conflicts with communication modules. A simple device reboot often resolves the issue when Wi-Fi stopped turning on or searching for networks.
The second important step is to check the router itself. The problem may not be with your phone. Redmi or Poco, but rather a frozen router. Unplug the router for 10-15 seconds, then plug it back in and wait for it to fully boot up. If other devices in the house also can't see the network, the problem is definitely with the ISP or the equipment.
⚠️ Attention: If the router's lights are on after rebooting, but the internet still isn't working, the problem may be with your provider. Check your account balance and whether there's any emergency maintenance on the line.
It's also worth paying attention to airplane mode. Sometimes the system gets stuck in this mode, and the communication module won't activate again. Turn airplane mode on for 5-10 seconds, then turn it off. This will force a restart of the radio module and may help the phone. Xiaomi start picking up a signal again.
Network settings and network (Forget network)
One of the most common reasons why a phone Xiaomi If your phone isn't connecting to Wi-Fi, there's a conflict with saved configurations. If you've changed the password, encryption type, or network name (SSID) on your router, but your phone is still trying to connect using the old settings, the connection will fail. In this case, the "Forget Network" feature can help.
To perform this procedure, go to the settings menu. Find the section Settings → Wi-FiIn the list of available networks, find your home network, tap it, and select "Delete" or "Forget this network." Then try connecting again using the current password.
Sometimes the list of saved networks becomes full, which is typical for devices that frequently move between different access points. The system may simply not know which configuration to apply. Removing unnecessary profiles frees up memory and eliminates logical errors during authorization.
☑️ Connection Failure Checklist
If your phone sees the network and says "Connected," but the internet isn't working, try changing your DNS settings. In the advanced Wi-Fi settings, change the IP settings from DHCP on Static and register DNS servers from Google: 8.8.8.8 And 8.8.4.4This often helps bypass provider blocking or routing errors.
Problems with the 2.4 GHz and 5 GHz frequency ranges
Modern routers operate in two bands: 2.4 GHz and 5 GHz. Older smartphone models Xiaomi Some phones may not support the 5 GHz frequency, while newer ones may (preferentially) select it, even if the signal there is weaker. If your router broadcasts two networks with the same name, the phone may "jump" between them, losing connection.
The 2.4 GHz band has better penetration and passes through walls better, but it has lower speeds and is more susceptible to noise from neighboring routers and microwaves. The 5 GHz band offers higher speeds but has poorer penetration through obstacles. Xiaomi It doesn't pick up Wi-Fi in a distant room, perhaps it's trying to hold on to a weak 5 GHz signal instead of switching to a stable 2.4 GHz.
| Characteristic | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Transfer speed | Up to 450 Mbps | Up to 1300+ Mbps |
| Range of action | High | Medium/Low |
| Penetration through walls | Good | Bad |
| Channel congestion | High (a lot of interference) | Low |
How to separate networks on a router?
Go to your router settings (usually 192.168.0.1 or 192.168.1.1). Find the Wireless or Wi-Fi Settings section. Disable Smart Connect (if available) and set different names (SSIDs) for the 2.4G and 5G networks, for example, HomeWiFi and HomeWiFi_5G.
It's recommended to set different names for the 2.4 GHz and 5 GHz networks in your router settings. This will allow you to manually select which network to connect to depending on your location. In your phone's Wi-Fi settings Xiaomi You can also find the option "Use Wi-Fi only when the Internet is available" - it is better to enable it so that the phone does not hang on a dead network.
MIUI power saving and optimization
shell MIUI and its new version HyperOS are known for their aggressive power optimization. The system can forcefully disable the Wi-Fi module when the screen is off to save battery. This results in notifications being delayed, and when the screen is turned on, the phone takes a long time to find a network.
To prevent the system from turning off Wi-Fi, go to the section Settings → Battery → Power SavingMake sure the "Performance" or "Balanced" mode is selected, not "Power Saver." Also, in the battery settings, find the "Settings" app or the system process responsible for Wi-Fi and allow it to run in the background.
⚠️ Attention: New versions of MIUI feature a "Wi-Fi Assistant." It automatically switches the phone to mobile data if the system detects a weak Wi-Fi signal. This can create the illusion of poor Wi-Fi performance.
Check your Wi-Fi Assistant settings. Go to Settings → Wi-Fi → Wi-Fi AssistantHere you can disable the "Switch to mobile network" feature or adjust the sensitivity threshold. This will prevent your phone from accidentally disconnecting from the router.
Resetting network settings and hardware problems
If software methods did not help, and Xiaomi If you still can't connect to Wi-Fi, try resetting your network settings. This will reset all network settings (Wi-Fi, Bluetooth, and mobile data) to factory defaults. Important: Wi-Fi passwords will be deleted and you'll have to re-enter them.
To perform a reset, follow this path: Settings → Connection and sharing → Reset Wi-Fi, mobile networks, and BluetoothTap the "Reset Settings" button at the bottom of the screen. After rebooting, your phone will be as good as new in terms of network connections, which often fixes deep system errors.
In rare cases, the problem lies in the hardware. This could be a loose antenna module inside the case (especially after a fall) or a faulty Wi-Fi chip. If the phone doesn't detect any networks even after a factory reset, there's likely a hardware problem.
The Impact of Third-Party Apps and VPNs
Users often forget that installed apps can monitor their network connection. VPN services, antivirus programs with Wi-Fi protection, or data-saving apps can block connections or redirect traffic, creating the illusion of no internet connection.
Try to start the phone in Safe modeIn this mode, only system apps are loaded. If Wi-Fi works reliably in Safe Mode, then one of your installed apps is causing the problem. Remove recently installed apps one by one, checking the results.
Pay special attention to apps that require geolocation access. In Android, scanning for Wi-Fi networks is closely tied to the GPS module. If you deny geolocation access for system services, network scanning may become unavailable or inaccurate.
How to enter safe mode on Xiaomi?
Press and hold the power button. When the power menu appears, press and hold the "Power off" icon on the screen. You'll be prompted to enter Safe Mode.
Frequently Asked Questions (FAQ)
Why does Xiaomi see 5GHz Wi-Fi but not connect?
Most likely, the wrong encryption type is selected, or the password contains special characters that the phone doesn't process correctly. Try changing the security type on your router to WPA2-PSK (AES) and simplify the password, leaving only letters and numbers.
My phone only picks up Wi-Fi near the router. What's the reason?
This may indicate a weakened antenna signal inside the phone or the use of the 5 GHz band, which has a short range. Try forcibly switching to the 2.4 GHz network and see if the situation improves in distant rooms.
Will resetting the router help if the phone can't see the network?
Yes, if the problem is due to the router's memory being full or a channel conflict. However, before resetting, make sure you have your provider's login information, as your internet settings may be lost.
Can a case interfere with Wi-Fi reception on a Xiaomi?
Yes, if the case has a metal insert, a magnetic clasp, or is made of thick material with a metallic coating. Remove the case and check the signal strength—this is a common, yet often overlooked, cause.
What should I do if Wi-Fi disappears after updating Android?
Updates sometimes change drivers or reset configuration files. Besides resetting the network, try clearing the cache in the Settings app through the app menu. If that doesn't help, wait for a patch from the manufacturer or try a new firmware update.
