When Xiaomi’s favorite smartphone suddenly stops seeing the home network or writes “Connect” status endlessly, it can unbalance any user. Most often, the problem lies in a software failure of settings or conflict IP-addresses, which is easily solved by restarting the router or resetting network parameters on the device itself.
However, if simple methods don’t work, it’s worth digging deeper. Redmi and POCO owners often encounter features of the MIUI or HyperOS shell that can aggressively control energy saving by turning off the Wi-Fi module to save charge, and outdated drivers or improperly set date and time can also affect, which blocks a secure connection to secure security protocols.
In this article, we will look at all possible causes, from simple password errors to complex antenna hardware malfunctions, how to properly clean the cache of network services, change the DNS settings, and when it is time to carry the device to the service center. It is important to act consistently so that you do not aggravate the situation with improper manipulation.
Basic diagnostics and equipment reloading
The first thing to do is to eliminate the trivial reasons that are often ignored in the heat of finding a complex solution. Make sure that the router is on the appropriate indicators, and other devices (laptop, tablet) are safely connected to the Internet. If the problem is only observed on the phone, try turning off and turn on Wi-Fi again in the notification curtain.
A critical step is to completely reboot the router. Routers, working for days without interruption, accumulate errors in RAM, which leads to a freeze. DHCP-Pull the router's power cord out of the socket, wait. 15-20 Just a second and turn it back on. Wait for the network to load.
⚠️ Note: Do not just turn off the router button, namely, turn off power from the network on the 15-20 seconds for complete discharge of capacitors and cleaning of buffers.
In parallel, reboot the Xiaomi smartphone itself, which will clear temporary files and restart the system services responsible for wireless modules, often after turning on the phone begins to see the network immediately.
☑️ Primary diagnosis
If you still have a problem after that, you can go to more detailed settings, sometimes to forget the network in the saved list and re-enter the password, which will force the phone to go through the authorization procedure again.
Date, time and region problems
One of the hidden but frequent reasons for the failure is to desynchronize system time. The WPA2 and WPA3 security protocols require the exact timing of the client and server to verify certificates. If your Redmi has a lost date (for example, it is 2020), the router will reject the connection request.
Check the date and time settings in the Settings menu → Additional → Date and time. Make sure the Use Network Time switch is activated. If the automatic setting doesn't work due to lack of network, set the current date and time manually, then try to connect.
Some Xiaomi models that are designed for the Chinese market or with a changed region in the settings may have restrictions on the use of certain Wi-Fi frequency bands. Try temporarily changing the region in the phone settings to India or Singapore to see if the behavior of the module changes.
Why is time so important?
Remember that changing your region can affect some system applications and ad integrations, so once the Wi-Fi problem is fixed, you can revert back to the region.
Reset network settings and clear cache
If the conflict is deep, resetting the network settings will help, bringing Wi-Fi, mobile Internet and Bluetooth back to factory values, and it's important to understand that your personal files, photos and contacts will not be affected, but all saved passwords from Wi-Fi networks will have to be re-entered.
To perform the reset, go to the Settings menu → Connection and sharing → Reset Wi-Fi, mobile network and Bluetooth. Click the Reset button at the bottom of the screen and confirm the action with an unlock code or a pattern lock.
| Action. | What's persisting | What's removed |
|---|---|---|
| Resetting network settings | Photos, contacts, annexes | Wi-Fi passwords, Bluetooth settings, APN |
| All data dumping | Nothing. | All the information on the phone. |
| Reboot. | All information. | Temporary files (cache) |
Another effective method is to clear the cache of Google Play services and system network components. Go to Settings → Apps → All apps, search the list of Google Play Services and select Clean → Clear Cache. A similar procedure can be done for the Settings app.
💡
After resetting your network settings, be sure to restart your device before trying to connect again so that the system reinitializes the network stack.
These actions eliminate most software errors accumulated during the operation of the smartphone, especially after firmware updates.
Router settings and frequency ranges
Modern routers often operate in two bands: 2.4 GHz 5 GHz – Old or budget Xiaomi models may not support 5 GHz or operating in this range is unstable. Try to divide networks in the router settings by giving them different names (for example, Home_2G and Home_5G), and connect to the network 2.4 GHz.
The problem can also be in the broadcast channel. If neighboring routers are running on the same channel, there will be interference. Go to the router settings (usually at 192.168.0.1 or 192.168.1.1) and in the Wireless Settings section, change the channel from “Auto” to a fixed one (for example, 1, 6 or 11 for 2.4 GHz).
It is also worth checking the type of encryption. WPA2-PSK (AES) is recommended for maximum compatibility with all Redmi and POCO devices. WPA3 or mixed modes (WPA2/WPA3) sometimes cause connection problems on smartphones with outdated Wi-Fi drivers.
⚠️ Note: Changing your router settings may temporarily interrupt the Internet on all connected devices. Make sure you know the router's admin panel password before making changes.
If you have a dual-band router, try disabling the Smart Connect feature, which automatically switches the device between frequencies, and often this algorithm doesn't work properly, and manually splitting the networks solves the problem.
Features of MIUI and energy saving
The MIUI shell is known for its aggressive battery optimization, which can kill background processes, including the Wi-Fi module, if the phone is in your pocket or the screen is off, which causes the phone to appear connected but the internet is down, or it to fall off all the time.
To fix this, go to Settings → Battery and Performance. Find Power Saving Mode and switch it to No Limits or Performance. Also, under Security → Battery, check if the back-end limit for system services is worth it.
Another useful feature is resetting Wi-Fi settings through the engineering menu, but it is not available on all firmware versions. A more secure analog is the command in the ##6484## (CIT menu) call menu, where you can run a WLAN test. If the test shows an error, the problem is likely hardware.
💡
Aggressive energy saving in MIUI is a common cause of unstable Wi-Fi. Disabling optimization for system services often solves the problem of breaks.
Remember to update your phone’s firmware regularly. With newer versions of HyperOS and MIUI, Xiaomi often fixes wireless driver errors that may have been embedded in previous builds.
Hardware malfunctions of the Wi-Fi module
If no software methods, resets, and flashing help, there is a high probability of physical failure. The Wi-Fi module in Xiaomi smartphones is soldered on the motherboard. When falls, bumps, or moisture hits, the contact may go away, or the chip itself may fail.
An indirect sign of a hardware problem is a grey or inactive Wi-Fi icon in the settings, or a complete lack of network search even after a reset, and the phone can get very hot at the top of the case when trying to turn on wireless communication.
In such cases, self-repair without soldering equipment and a microscope is impossible, and professional diagnostics is required in a service center, where masters can “warm up” the chip (rebolling) or replace the entire module.
Can I use my phone without Wi-Fi?
Don’t try to heat your phone with a hair dryer or tap on the body – this will only make things worse and can damage other components, such as the screen or battery.
