Wi-Fi network without Internet access on Xiaomi Redmi: what to do if the phone is connected, but does not work

You've connected to your home or public Wi-Fi network on your Xiaomi Redmi, but your browser persistently issues a "No Internet connection" error and messengers don't update messages? This problem is familiar to many smartphone owners of the brand - especially after updating MIUI or changing the router, and in 80% of cases it can be solved independently without contacting the service center.

Unlike the complete absence of a signal, when the phone does not even see the network, the situation here is paradoxical: the Wi-Fi indicator is on, the speed is displayed as “0 Kb / s”, and the exclamation mark icon in the tray signals problems. The reasons lie either in the settings of the router, or in software failures. MIUI, or IP-We're going to go through all the scenarios, from basic checks to hidden engineering menu features that aren't written in the official manuals.

Important: if the problem occurred after installing custom firmware or root rights, the algorithm of actions will be different - read about this in a separate section. To begin with, we will check the standard solutions that work on the Redmi Note 10/11/12, Redmi 9/10 and other models of the series.

1. Diagnostics the problem: why Wi-Fi is connected, but there is no Internet

Before you move on to fixes, identify the exact cause of the problem, which will save time and eliminate unnecessary manipulation.

• 🔄 Wi-Fi icon with exclamation mark - phone gets IP-The router's address, but it can't get online, most of the time it's the fault. DNS-servers or router settings.
• 📶 The 0Kb/s speed in the notification panel is no data exchange, the problem can be on the phone or the provider side.
• 🔒 “Connected, without network access” is a typical symptom of conflict IP lock-in MAC-address.
• 🌐 Some websites work, but not all are the problem. DNS or parental control restrictions on the router.

First, check if the Internet works on other devices (laptop, tablet, second phone). If so, the problem is in the settings of Xiaomi Redmi. If not, it is the router or provider. IPv4/IPv6-Addresses in connection properties (more on this in the next section).

2. Basic checks: router, provider, phone settings

Start with the basics that are often ignored, and go straight to the complex settings, which take no more than 5 minutes, but solve the problem in 30% of cases.

Restart the router (turn off power for 30 seconds)

Check the balance with the provider (if the tariff is with a limit)

Turn off VPN or proxy in your phone settings

Try connecting to another Wi-Fi network (neighbor, public)

Make sure the router does not activate Guest Mode with restrictions-->

Router reboot – a universal way to reset temporary errors DHCP. Turn off the router for 30 to 60 seconds, then turn it back on. Wait for full load (the indicators should burn steadily). If the Internet went live after that, the problem was the distribution failure. IP-address.

If you are using a dual-band router (2.4 GHz) + 5 GHz, try connecting to a different frequency. Sometimes Xiaomi Redmi does not work well with 5 GHz networks because of the Wi-Fi module drivers. Also check if the router settings are limited to the limit on the network. MAC-Address – some providers are blocking new devices.

⚠️ Warning: If the router only rebooted the Internet on other devices, but not on Redmi, the problem is definitely in the phone. Go to sections 3-5. If the Internet does not work on any device, call the provider or check the settings of the router.

3. reset network settings on Xiaomi Redmi

One of the most effective methods is to reset the network settings, and it removes all the stored Wi-Fi networks, Bluetooth devices, and VPN-configuration, back to factory settings. This helps if the problem is caused:

• 🔧 Wrongly appointed IP-Address (for example, static instead of dynamic).
• 🔒 Conflict. DNS-servers after connecting to public networks.
• 📱 Failure of the Wi-Fi module after the update MIUI.

How to perform the reset:

1. Open Settings → System and device → Additional → Resetting.
2. Select Network Reset (not to be confused with a full reset!).
3. Confirm the action with a password or pattern lock.
4. After restarting, connect to Wi-Fi again by entering the password.

If the problem persists after the reset, go to manually configure IP and DNS (Section 4). Also check if there are any traffic-saving apps on the phone (such as Security or Data Saver) - they can block background network access.

💡

Before resetting the network, save your Wi-Fi passwords in a notebook or take a screenshot of the list of saved networks in Settings → Wi-Fi

4. IP and DNS Manual Assignment: If DHCP is not working

If the router does not give the correct IP-The address (or the wrong range) will not be able to access the Internet despite the connection, in which case manual network settings will help.

First, check the current settings:

1. Connect to a problematic Wi-Fi network.
2. Go to Settings → Wi-Fi → [click on network name] → More.
3. Look at the parameters. IP-address, gateway and DNS. If IP begin 169.254.x.x — it's a sign of failure DHCP.

Now let's set the static parameters:

1. In the same menu, select Settings. IP → Static.
2. Enter the data in the table below (replace the last IP digits with any 10 to 254 not used by other devices):

Once you save your settings, reconnect to the network. If the Internet works, the problem was automatic reception. IP. If not, try alternatives. DNS (For example, 77.88.8.8 from Yandex) or check whether the router is blocking your router. MAC-address.

5.Problems after MIUI Update: Cache Reset and Change Recoil

MIUI updates often bring not only new features but also bugs — especially in Wi-Fi and Bluetooth modules. If the problem appears immediately after the update, try the following steps:

• 🧹 Cleaning the system cache: Go to Settings → Annexes → App management. Press the three dots at the top. → Show system. Find Wi-Fi settings and Wi-Fi Service, clear the cache for both.

Related: Retreat of the update

1. Open Settings → About the phone → System update.
2. Press three points. → Update package.
3. Remove the last downloaded package and restart the phone.

Reset to factory settings

If nothing works, complete a reset via Settings → System & Device → Reset → Delete all data. Before doing so, be sure to back up through Settings → Additional → Backup and Reset as all data will be erased.

If the reset didn’t work, check if the phone has custom Recovery (such as TWRP) or root rights installed. These may conflict with the updated MIUI modules. In this case, you will need to flash through Fastboot — read about this in the next section.

⚠️ Warning: Once reset to factory settings, the phone will require you to enter the Mi Account that was previously tied.If you don't remember it, unlocking can take up to 72 hours (as per Xiaomi policy).

6. Advanced methods: engineering menu and firmware

If standard methods don't work, it's time to move on to hidden settings and low-level fixes, which require caution but often solve problems that can't be fixed through a conventional interface.

Method 1: Resetting a Wi-Fi module through an engineering menu

1. Open the Phone app and enter the combination: ##4636##.
2. Select Wi-Fi (or Wi-Fi Information) information.
3. Click on the three dots at the top → Wi-Fi refresh rate → select 1500 ms.
4. Go back and select Disable Wi-Fi, then Enable Wi-Fi again.

Method 2: Flash the Wi-Fi module over Fastboot (power users only!)

If the problem is caused by file damage /system/etc/firmware, It will help the original WCNSS_qcom_cfg.ini:

fastboot flash wcnss_qcom_cfg.ini wcnss_qcom_cfg.ini


fastboot reboot

File. wcnss_qcom_cfg.ini You can extract from the official firmware for your Redmi model (download from the Xiaomi Firmware website).

Method 3: Checking the Wi-Fi antenna

If the phone is not catching the network more than 2-3 meters from the router, there may be a hardware malfunction (unconnection of the antenna or damage to the module).

1. Remove the back cover (on models with a removable body).
2. Make sure that the Wi-Fi antenna contacts (thin gold wires) are not deviated from the board.
3. If you have soldering experience, check the integrity of the tracks around the module. BCM43xx or QCA6xxx (model-wise).

💡

If after hardware check the problem remains, and the phone warranties - contact the service center Xiaomi. Independent repair of the antenna may deprive the warranty.

7. Alternative ways to access the Internet

While you are looking for a solution, you can temporarily use other connection methods:

• 📶 Mobile Internet (4G/5G): Activate data transfer in Settings → SIM-If the tariff is limited, turn on Traffic Saving Mode in the same menu.
• 🔌 USB-Tethering from another phone: Connect Redmi over USB to another smartphone with a working Internet and turn on USB-modem in the settings of the access point.
• 🔄 Modem mode on PC: If you have a computer with network access, connect your phone to USB, Enable data transfer by USB Use the Reverse Tethering program (requires root rights).
• 📡 Public Wi-Fi: Connect to a cafe, mall or library. Many establishments provide free Wi-Fi without registering.

For long-term use of alternative methods, set up automatic switching:

1. Open Settings → Connections and Sharing → Data Transfer.
2. Enable the option of Auto-Switching between Wi-Fi and mobile network.
3. Set a mobile traffic limit to avoid unexpected expenses.
