The situation when the smartphone Xiaomi, Redmi or POCO Many users are familiar with the problem of their home network not being detected or constantly seeing "Connecting..." messages. This isn't just an annoying glitch, but a real problem that blocks access to messaging apps, navigation, and work tools. Often, the cause isn't a hardware failure, but a software conflict or a misconfigured router.
Owners AndroidDevices regularly encounter this problem due to aggressive battery optimization, which can kill background processes in the wireless module. Before taking the device to a service center, it's worth trying to restore the connection using software. In most cases, this helps restore stable operation without unnecessary costs.
Next we will look at the main reasons why Wi-Fi on the phone Xiaomi If something isn't working correctly, we'll provide step-by-step troubleshooting instructions. It's important to proceed sequentially, eliminating simple factors before moving on to more complex settings.
Primary diagnostics and module reboot
The first thing you should do if you have no internet is to check the physical availability of the network. Make sure the router is turned on and the appropriate indicators are lit. Sometimes the problem can be resolved with a simple hardware restart: unplug the router from the power outlet for 10-15 seconds, then plug it back in. This will clear any temporary errors. network card.
The smartphone itself also needs to be rebooted. In the system MIUI or HyperOS This clears the network services cache. If the phone still won't connect after turning it on, try switching to airplane mode. Activate it for 5-10 seconds, then deactivate it. This will force a restart of the device's radio module.
If simple methods don't help, check if Wi-Fi is working on other devices. If the internet is working on the laptop, but not on Redmi, then the problem is localized specifically to the phone. In this case, it's worth checking the date and time settings. Incorrect timestamps can block a secure connection to the servers.
Checking date and time settings
One of the hidden but critical reasons for access denial is system time desynchronization. Security protocols SSL/TLS require the time on the client and server to match exactly. If your Xiaomi If the date is incorrect, the router may reject the authorization request, considering it invalid.
To fix this, go to the settings menu. You need to find the section responsible for additional system settings. Typically, the path looks like this: Settings → Advanced settings → Date and timeMake sure the "Use network time" switch is enabled. If it's already enabled, try disabling it, manually setting the correct values, and then enabling automatic syncing again.
⚠️ Attention: If the time on your phone keeps resetting after turning it off, it could indicate a dead internal CMOS battery or a deep system failure that requires a firmware update.
After adjusting the time, try forgetting the network and reconnecting. To do this, click on your network name in the list of available networks and select "Delete" or "Forget." Then re-enter the password. This will initiate a new handshake with the router using the correct timestamps.
Resetting network settings on Xiaomi
If the issue is software-related and stems from accumulated configuration errors, a full network reset will help. This will return Bluetooth, mobile data, and Wi-Fi settings to factory defaults. It's important to understand that saved passwords for all networks will be deleted.
To perform the operation, go to the section Settings → Connection and Sharing → Reset Wi-Fi, Mobile Network, and BluetoothThe system will ask you to confirm the action by entering your screen unlock PIN. After the reset, the phone will reboot, and you will need to re-enter your home router password.
☑️ Checklist before resetting the network
This method is especially effective if you've recently updated your firmware or replaced your router. Old configurations may conflict with new encryption protocols. A reset removes old static IP addresses and DNS records that may be stuck in the system.
Setting up a static IP address
A common reason why Xiaomi If the Wi-Fi connection fails, there's an IP address conflict on the local network. The router can assign addresses via DHCP, but if there are no available numbers in the pool or a collision occurs, the phone won't be able to access the network. The solution is to manually assign a static IP address.
In the list of available networks, click the arrow next to your router's name or select "Edit." In the "IP Settings" field, change the value from DHCP on StaticAdditional fields for entering data will open. The gateway is usually the same as the router address (often 192.168.0.1 or 192.168.1.1).
In the IP address field, enter a value that is different from other devices, for example, if the router 192.168.1.1, ask the phone 192.168.1.150You can specify public DNS, for example, from Google: 8.8.8.8This often solves the problem of long connection times.
After entering the data, click "Save." The phone will reconnect to the network using a fixed address. This eliminates address distribution errors within the local network and often speeds up system response.
Diagnostics of frequency ranges and channels
Modern routers operate in two ranges: 2.4 GHz And 5 GHzOld models Xiaomi They may not support 5 GHz, while newer ones may ignore 2.4 GHz under certain power-saving settings. Channel congestion may also be the issue.
If your phone sees the network but won't connect, try separating the network names (SSIDs) on your router. Give them different names, for example, Home_2G And Home_5GThis will force the phone to connect to the desired frequency band. For older devices, 2.4 GHz is preferable due to its better penetration.
You can change the broadcast channel in your router settings (accessible via a browser). If neighboring routers are operating on the same channel, interference will occur. Automatic channel selection isn't always effective. It's better to manually select channels 1, 6, or 11 for the 2.4 GHz band, as they don't overlap.
MIUI power saving issues
Branded shell MIUI is known for its aggressive power management policy. The system can forcibly disable the Wi-Fi module if it detects an app using the network is inactive or if the battery is low. This often leads to connection drops.
To prevent the system from throttling your connection, go to Settings → BatteryClick the gear icon in the upper right corner. Find the "Sleep" option or app-specific power saving settings and disable restrictions for system Wi-Fi services. It's also worth disabling the "Turn off Wi-Fi during sleep" option if available in the advanced settings.
Another important setting is "Wi-Fi Assist." This feature automatically switches your phone to mobile data if the Wi-Fi signal appears weak. This can create the illusion that your Wi-Fi is down. Disable this feature in the Wi-Fi menu by tapping the arrow next to the network name or in the general settings.
⚠️ Attention: The power saving menu interface may differ depending on the version MIUI or HyperOSIf you don't find an exact match, look for similar names related to "Optimization" or "Sleep."
Factory reset (Hard Reset)
If none of these methods help, the system files responsible for wireless modules may be damaged. In this case, a radical but effective solution remains: a hard reset. This will return the phone to its out-of-the-box state.
Before starting the process, be sure to back up your data. The reset will delete all photos, contacts, and apps. Go to Settings → About phone → Factory data reset → Erase all dataThe process will take a few minutes, after which the phone will turn on as if it were new.
What to do if resetting doesn't help?
If your phone still won't connect to Wi-Fi even after a full reset and reflashing, there's a high probability of a hardware problem. This could be a broken antenna module or a faulty wireless chip. In this case, diagnostics at a service center using a multimeter and soldering are required.
After turning it on, try connecting to the network without installing any unnecessary apps. If Wi-Fi works, then the problem was a software conflict. If the error persists even on a clean system, then it's a software issue. hardware failure.
Table of possible errors and solutions
For quick diagnosis, use the summary table. It will help you match the symptom with the most likely cause and solution.
| Symptom | Probable cause | Solution method |
|---|---|---|
| Endless "Connecting..." | Incorrect password or encryption type | Forget the network, check the password, change the encryption type to WPA2 |
| "Failed to obtain IP" | DHCP error or address conflict | Set a static IP, reboot the router |
| Wi-Fi is gray and won't turn on. | Driver or module failure | Resetting, reflashing, repair |
| Connects and disconnects immediately | Power saving or weak signal | Disable power saving, check the 2.4/5 GHz band |
Frequently Asked Questions (FAQ)
Why can't Xiaomi see the 5 GHz network?
Your phone may not support this standard (typical for budget models released before 2018-2019). Also, check your router's region settings: some countries block certain channels in the 5 GHz band. Change your router's region to the US or Russia.
Can a case interfere with Wi-Fi?
Yes, if the case has a metal base or a metal coating. Metal shields the antenna signal. Remove the case and check the reception quality. Thick walls or mirrors placed between the router and the phone can also block the signal.
What is MAC filtering and how does it affect?
This is a router security setting that allows access only to certain devices. If MAC address filtering is enabled on the router and your phone isn't on the "white" list, the connection will be blocked even with the correct password. Check your router settings.
Does changing DNS help with connection?
Changing your DNS (for example, to Google DNS 8.8.8.8) often solves the problem of slow page loading, but it can also sometimes help with connection errors if your ISP blocks standard DNS requests. It's worth trying this in your static IP settings.
