Smartphone owners Xiaomi, Redmi And Poco periodically encounter an unpleasant situation when the device suddenly stops connecting to the wireless network. This can happen on new models with a shell MIUI 14, as well as on devices manufactured several years ago. The problem often arises suddenly: yesterday everything was working fine, but today the phone endlessly obtains an IP address or simply ignores the router.
The reasons for this behavior may lie in software failures of the operating system itself Android, as well as router settings conflicts. Sometimes the culprit is a static IP address or changes in security protocols that the phone hasn't had time to accept. It's important to understand that hardware failure Wi-Fi modules are extremely rare, and in 90% of cases the situation can be corrected using software methods.
In this article, we'll detail the main scenarios that lead to connection loss and offer a step-by-step solution. You'll learn how to properly configure network settings, whether to use the reset function, and which hidden settings may be blocking access. A common cause of errors is a static IP address that conflicts with the router's DHCP range. We'll cover every detail so you can quickly get your gadget back in working order.
Basic diagnostics and simple solutions
Before delving into complex settings, it's important to rule out basic errors. Often, the problem can be resolved by simply rebooting the device or router, which clears temporary caches and re-initiates the handshake between the devices. If the phone Xiaomi If your phone doesn't connect to Wi-Fi, first try turning the wireless module off and on through the notification shade.
Sometimes the system MIUI The phone may be stuck waiting for network connection. In this case, rebooting the smartphone itself can help. This clears the RAM and forces a restart of all system services, including connectivity. It's also worth checking whether Airplane Mode is enabled, as it may have been activated accidentally.
☑️ Primary diagnostics
If simple methods don't help, it's worth checking if the internet is working on other devices on the same network. This will help you determine whether the problem lies with your phone or your provider's equipment. If other devices work fine, then the problem is localized to yours. Xiaomi.
IP and DNS issues
One of the most common reasons why a phone Xiaomi If it doesn't connect to Wi-Fi, there is an IP address conflict. By default, the device tries to obtain an address automatically via DHCP, but sometimes this process fails, and the phone gets stuck at the "Obtaining IP address" stage. In this situation, manual configuration helps.
To resolve this issue, go to your Wi-Fi settings, click on your network name or the arrow next to it, and select "Edit." In the advanced settings, find "IP Settings" and toggle it off. DHCP on StaticYou will need to enter the gateway address (usually 192.168.0.1 or 192.168.1.1) and DNS servers.
Which DNS servers should I use?
It is recommended to use public DNS from Google (8.8.8.8 and 8.8.4.4) or Cloudflare (1.1.1.1), as they often work more reliably than standard provider ones, especially if the operator is experiencing failures in request routing.
Using a static IP can be a temporary workaround, but it doesn't always solve the problem permanently. If the error persists after entering the settings, it may be a DNS issue. Try entering the address in the DNS 1 field. 8.8.8.8, and in the second field 1.1.1.1This often helps if your ISP blocks standard requests.
⚠️ Attention: When manually setting up a static IP, make sure you don't use an address that's already occupied by another device on the network, otherwise an address conflict will occur and the Internet will not work for any of the devices.
It's also worth paying attention to the IP protocol version. Some older routers may not work correctly with it. IPv6, which modern smartphones try to use by default XiaomiIn the network settings, try switching the protocol to IPv4, if such an option is available in your menu.
Network settings failure and reset
If manipulating the IP address doesn't work, the system may have accumulated errors in the saved network profiles. Shell MIUI Sometimes it doesn't correctly handle changes to passwords or encryption types on the router, continuing to try to connect with the old data. In this case, the best solution is to delete the network.
Go to the list of available networks, select the one causing the problem, and tap "Delete" or "Forget this network." Then, re-enter the password. This forces the phone to completely recreate the connection profile from scratch, ignoring old cached data.
In more complex cases, when your phone won't connect to any network except mobile data, a full network reset may be necessary. This won't delete your personal photos or contacts, but it will clear all saved Wi-Fi passwords, Bluetooth settings, and mobile network settings.
To perform a reset, follow the path Settings → Connection and sharing → Reset Wi-Fi, mobile networks, and BluetoothConfirm the action and reboot your device. After enabling, you'll need to re-enter the passwords for all your wireless networks.
Date, time and regional settings
Few people know that an incorrect date and time can block connections to secure networks. Security protocols WPA2 And WPA3 use certificates whose validity is checked against the system time. If on your Xiaomi It's 2020, but it's 2026, and the router may reject the connection.
Check if you have automatic time synchronization enabled. To do this, go to Settings → Additional settings → Date and timeMake sure the "Use network time" switch is enabled. If the time is constantly out of sync, the motherboard battery may be dead, but this is unusual for a smartphone.
It's also worth checking your device's region. Some Wi-Fi features and frequency bands depend on the selected region. If you've moved or changed your SIM card, the region may have shifted. Make sure your settings are set to your actual region of residence so your phone uses the authorized frequencies.
| Parameter | Recommended value | Where to check |
|---|---|---|
| Date and time | Automatically (over the network) | Settings → Date and Time |
| Region | Russia (or your country) | Settings → Additional settings → Region |
| Language and input | Russian | Settings → Additional settings |
| Time zone | Automatically | Settings → Date and Time |
After adjusting the time and region, be sure to reboot your device. This will allow system services to re-initiate the authentication process with the router using the correct timestamps.
Impact of Android and MIUI versions
Software is the heart of a smartphone, and sometimes it is where bugs that interfere with the normal operation of communication modules are hidden. If your Xiaomi stopped connecting to Wi-Fi after a system update, maybe a new version MIUI contains compatibility errors.
Check for updates. Often the company Xiaomi promptly releases patches that fix critical connectivity issues. Go to Settings → About phone and click on the shell version. If an update is available, install it.
However, the opposite situation also happens: a new firmware breaks Wi-Fi. In this case, users often look for ways to roll back to the previous version, but this is a complex process that requires unlocking the bootloader. It's easier to wait for the next patch or perform a full data reset (with a backup first).
⚠️ Attention: The settings interface and menu item layout may vary depending on the MIUI version (12, 13, 14, HyperOS) and regional firmware (Global, China, EEA). If you can't find the item you're looking for, use the settings search.
It's also worth noting that older versions of Android may no longer support new encryption protocols implemented by ISPs and router manufacturers. If your device is many years old, it may simply not be able to handle the new network security standards.
Hardware problems and the Wi-Fi module
If all software methods have been exhausted and the phone still doesn't detect or connect to networks, a hardware problem cannot be ruled out. Wi-Fi module in smartphones Xiaomi — is a miniature chip that can fail due to a fall, moisture, or a manufacturing defect.
Symptoms of hardware failure often include: a complete lack of network listing (graylisting), constant connection drops even near the router, or heating of the bottom of the case near the antenna. The phone may also display "No Service" or constantly search for networks, draining its battery quickly.
Home diagnostics are limited, but you can try launching the engineering menu. Enter the code into the dialer. ##6484## (does not work on all models) and select the test WLANIf the test doesn't run or returns an error immediately, this is a clear sign of a hardware problem.
If a hardware fault is confirmed, you'll need to contact a service center. Replacing the Wi-Fi module in modern smartphones yourself Xiaomi is extremely complex, as it is often soldered onto the motherboard or integrated into a common communication module.
Frequently Asked Questions (FAQ)
Why does my Xiaomi phone say "Saved" but there is no internet?
This means authentication was successful, the password is correct, but data exchange is not occurring. Most often, the problem is DNS, incorrect time on the device, or router blocking (MAC filtering). Try setting the static DNS to 8.8.8.8.
How to reset network settings on Xiaomi?
Go to Settings → Connection and sharing → Reset Wi-Fi, mobile networks, and BluetoothTap the "Reset settings" button at the bottom of the screen. You will be asked to enter your screen unlock password.
Can a case interfere with Wi-Fi?
Yes, if the case has a metal base or contains metal inserts. Metal shields the signal. Remove the case and check if the signal improves.
What to do if Wi-Fi is slow only on Xiaomi?
Check if power saving mode, which limits background network activity, is enabled. Also, try changing the Wi-Fi channel in your router settings to a less congested one (1, 6, or 11 for 2.4 GHz).
Does a factory reset help?
Yes, this is a radical method that removes all software errors and settings conflicts. However, be sure to back up your important data beforehand, as all files will be deleted.
