Wi-Fi is connected, but there is no Internet on Xiaomi: full troubleshooting instructions

You've connected to Wi-Fi on a Xiaomi smartphone, but your browser persists in showing "No Internet connection" and your messengers aren't updated? Or Mi Router router gives you a network but your devices can't get online? This problem is familiar to millions of users, and it can be caused by both the settings of the gadget and the parameters of the router. In 80% of cases, you can fix the problem yourself without going to the service center.

In this article, we will examine all possible reasons why the Wi-Fi network on Xiaomi devices works without access to the Internet: from banal failures in settings to hardware malfunctions. You will learn how to diagnose a problem, which parameters to check first, and what to do if standard methods do not help. MIUI Xiaomi routers, which are often a source of headaches.

1. Diagnosis of the problem: we identify the culprit

Before you jump to reboot your router or reset your smartphone, it's important to understand where the crash occurred, and there are three areas where the problem can be:

• 📱 Xiaomi device (smartphone, tablet, smart watch, TV) – wrong network settings, failure MIUI, traffic blockage.
• 📶 Xiaomi router (or other brand) – wrong settings DHCP, Firmware failure, restrictions on MAC-address.
• 🌍 Provider – technical work, blocking on IP, face-counting.

To narrow down the search, do simple checks:

1. Connect another device (laptop, second smartphone) to the same Wi-Fi network. If the Internet works, your Xiaomi is a problem.
2. Restart your router and check if the INTERNET (or WAN) indicator is on. If not, call the ISP.
3. Try connecting to another network (like the mobile Internet), and if it works, it's the current Wi-Fi.

If the problem only manifests itself on one device, go to the section about the settings of Xiaomi. If the Internet is not available on all gadgets, check the router or communication with the provider.

2. Wi-Fi settings on Xiaomi smartphone: what to check first

MIUI firmware is known for its abundance of hidden features that sometimes conflict with networks. Here are 5 key parameters worth checking out:

Traffic Savings and Background Activity

MIUI has aggressive traffic optimization that can block Internet access for individual applications, to turn off restrictions:

1. Go to Settings → Connections and Sharing → Data Use.
2. Slip on Traffic Saving and turn it off.
3. Go back and select Background Data Use → turn on for all applications.

If the problem occurs after the MIUI update, check the permissions for system applications:

• 🔧 Go to Settings. → Annexes → Application management.
• 🔍 Find Google Play Services and Google Play Store.
• 📥 Enable Auto Start, Background Activity and Data Use.

Resetting network settings

If the previous steps didn't work, reset the network settings, which will delete all the stored Wi-Fi networks and VPNs, but return the factory connection settings:

Settings → About phone → Resetting → Resetting Wi-Fi, mobile network and Bluetooth settings

Attention! Once reset, you'll have to re-enter all Wi-Fi passwords.

3. problems with the Xiaomi router: setting up DHCP and DNS

If the internet is not available on all devices connected to the router, the problem lies in its settings. 4A/4C/AC2100) often suffer from failures in DHCP and DNS. Here's what we need to do:

3.1. Verification of connection to the provider

Make sure the router is connected to the Internet correctly:

1. Open the router’s web interface at 192.168.31.1 (or via the Mi Wi-Fi app).
2. Go online. → Status.
3. Check the status of the connection. If it says Disabled or Authentication Error, the problem is on the provider side.

For models that support PPPoE (such as the Mi Router AX6000), make sure that the correct ones are entered:

• 🔑 Login and password from the provider (they are specified in the contract).
• 🌐 Type of connection (dynamic) IP, PPPoE, Static IP).
• 🔄 Regime. VLAN (if required by the provider).

Shift DNS-server

Sometimes ISP DNSs are unstable. Try using public DNSs from Google or Cloudflare:

To change the DNS on the Xiaomi router:

1. Go to the Additional settings → Network → DNS.
2. Enter the addresses from the table above.
3. Save the settings and restart the router.

💡

If the internet is up after the DNS change, but some sites are not open, try the Google DNS + Cloudflare combination (8.8.8.8 and 1.1.1.1).

Update to the router firmware

Outdated firmware can cause conflicts with modern devices.

1. Open the Mi Wi-Fi app.
2. Go to General → Update firmware.
3. If a new version is available, click Update.

Attention! Do not turn off the router during the upgrade. If the process is interrupted, the device may turn into a brick and require recovery via TFTP.

4. Specific problems of MIUI firmware

MIUI firmware (especially versions 12-14) has several pitfalls that make Wi-Fi work without the Internet, and these are the most common:

Conflict with the function "Dual connection"

Dual Connection (Wi-Fi + Mobile Data) sometimes blocks traffic to turn it off:

→ SIM-maps and mobile networks → Dual connection → Disable

4.2.Dumping MAC-address

Some routers block devices with suspicious» MAC-Addresses. MIUI shift function MAC, helper:

1. Go to Settings → Connections and Sharing → Wi-Fi.
2. Tap on the current network. → Additionally.
3. Choose a Private. MAC-address → Use it. MAC-address.

Mistake 4.3 «IP-address not received»

If the smartphone writes Receipt IP-addresses, but never connected:

• 🔄 Reboot the router and smartphone.
• 📱 On your smartphone, forget the network and connect again.
• 🖥️ On the router, check if it is turned on. DHCP-server (to the Local Network) → DHCP).

5. Hardware malfunctions: when without service can not do

If all software methods have been tried, but Wi-Fi is still without internet, hardware problems may occur:

• 📡 Damaged Wi-Fi module in the smartphone (often after falls or moisture).
• 🔌 Faulty. WAN-port on the router (check if the Internet indicator is on).
• ⚡ Power failure (if the router spontaneously restarts).

Critical sign of hardware malfunction: Wi-Fi is working, but the Internet indicator on the router flashes orange or does not burn at all – this means no communication with the provider on the physical level.

For diagnosis:

1. Connect the ISP cable directly to your computer (bypassing the router), and if the Internet comes up, the router is a problem.
2. Check the integrity of the cable (bend it in different places – if the indicator on the router starts to flash, the cable is damaged).
3. If the smartphone does not see any Wi-Fi network, most likely, the module has failed (replacement is required).

⚠️ Attention! If the Xiaomi router stopped turning on after a power surge, do not try to repair it yourself - life-threatening voltages may remain in the power supply.

6. Alternative ways of connecting

If you can’t fix the problem with Wi-Fi, use alternative methods of connection:

Modem mode (distribution of the Internet from the phone)

If you have mobile internet on your smartphone, you can distribute it to other devices:

Settings → Connections and Sharing → Modem Modem → Wi-Fi Access Point

6.2. Connection via USB (USB-ethernet)

For Xiaomi routers with USB-Port (for example, Mi Router 4 Pro):

1. Connect. 4G-modem USB-router.
2. In the router settings, select USB-modem as a source of the Internet.

Use of Powerline Adapters

If Wi-Fi is unstable but there is a working wiring, use Powerline adapters (e.g. Xiaomi Mi Powerline) that transmit the Internet over electrical wires.

7. Frequent questions and answers

💡

V 90% In some cases, the problem is solved by resetting the network settings on your smartphone or restarting the router. If it does not help, check the settings. DHCP/DNS and firmware updates.
