Wi-Fi on Xiaomi Redmi connects, but internet doesn't work: all the causes and solutions

You have turned on Wi-Fi on your Xiaomi RedmiYour phone has successfully connected to the internet, but your browser stubbornly displays the "No Internet Connection" error, and your messaging apps aren't updating? This problem is familiar to many smartphone owners. Redmi Note 10/11/12, Redmi 9/10 and other models based on MIUIIn 80% of cases, the culprit is a faulty router or a glitch in the phone's firmware—but there are also less obvious causes that aren't mentioned in standard instructions.

In this article we will look at 7 Key Reasons, Why Xiaomi Redmi connects to Wi-Fi without internet access - due to trivial errors in the settings IP/DNS to specific bugs MIUI 13/14You will receive step-by-step instructions with screenshots (for current firmware versions), a comparison table of diagnostic methods, and answers to frequently asked questions. We will pay special attention to the problem with "gray" IP addresses (169.254.xx), which occurs en masse after the MIUI update in 2026.

1. IP Address Issues: Why is my phone receiving 169.254.xx?

If your Xiaomi Redmi connects to Wi-Fi, but in the status bar next to the network name there is an exclamation mark, and in the network settings you see an IP address like this 169.254.x.x — this is a sure sign of a problem with retrieving network parameters. This address is assigned automatically when the phone is unable to obtain a valid IP address from the router.

Reasons for the emergence of a “gray” IP:

• 🔌 The router's DHCP server is disabled. or does not work correctly (often after a reset).
• 📡 Network congestion: too many devices are connected to one router (relevant for budget models) TP-Link or D-Link).
• 🔄 IP conflict: Another gadget on the network is already using the address that the router is trying to assign to your phone.
• 🛠️ MIUI crash: after updating the firmware, the service DHCP client may work unstably.

How to check and fix:

1. Open Settings → Wi-Fi, tap on your network and see the current IP address.
2. If the address starts with 169.254, go to Settings → Connections → Advanced → IP Settings and select Static IP.
3. Enter manually:

   IP address: 192.168.1.100 (or another free one in your router's range)
   Gateway: 192.168.1.1 (usually the same as the router address)
   Subnet mask: 255.255.255.0
   DNS 1: 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare)

4. Save your settings and reconnect to the network.

⚠️ Attention: If after manually entering the IP the Internet works, but after some time the problem returns, reset the router settings to factory settings (Reset button for 10 seconds). This will eliminate possible errors in the operation of the DHCP server.

2. DNS failures: why websites don't open even though Wi-Fi is connected

Another common reason for the “dead” internet on Xiaomi Redmi - incorrect operation DNS serversWhile the phone may successfully connect to the network and display a valid IP address, browsers and apps won't load data. Check this:

• Open your browser and try to access the website using its IP address (for example, 142.250.186.46 instead of google.com). If the page opens, the problem is definitely with DNS.
• Launch the application Ping & DNS from Google Play and run a DNS server test.

3. MIUI Bugs: Why Did the Internet Disappear After the Update?

Firmware MIUI is known for its "surprises" after updates. In 2026, users Redmi Note 11/12 There were a lot of complaints about the problem: after installing the latest version of MIUI, the phone connects to Wi-Fi, but the Internet only works in some applications (for example, in YouTube), and browsers and instant messengers remain offline.

Reasons:

• 🔧 Service failure ConnectivityService — is responsible for connection management.
• 📱 Conflict with applications, using VPN or proxy (for example, AdGuard or 1.1.1.1).
• 🔄 Incorrect settings migration after the update.

How to fix:

1. Clearing MIUI services cache:

   Settings → Applications → Manage applications → Three dots (⋮) → Show system → Find "ConnectivityService" and "WifiService" → Clear cache and data.

2. Disabling VPN/proxy: Go to Settings → Connections → VPN and deactivate all active connections.
3. Reset network settings: As described in the previous section.
4. Roll back the update (if the problem appeared recently): IN Settings → About phone → System update Click on the three dots (⋮) and select Delete the last update.

What to do if resetting doesn't help?

If the problem persists after resetting network settings, try roll back the firmware manually through FastbootTo do this, download the official firmware from the website. Xiaomi (chapter Download), connect your phone to PC and use the tool Mi Flash Tool. Attention: This will result in a complete data wipe!

⚠️ Attention: If you are using a custom firmware (eg. LineageOS or Pixel Experience), the problem may be a kernel incompatibility with the Wi-Fi drivers. In this case, the only solution is to flash the firmware to the official MIUI.

4. Router-side issues: what to check first

In 30% of cases, the router, not the phone, is to blame. This is especially true if the problem occurs on all devices at once. Here's what to check:

Top 5 reasons from the router:

• 🌐 Incorrect WAN settings: the provider has changed the connection parameters (for example, from Dynamic IP on PPPoE), and you have not updated the configuration.
• 🔒 MAC address blocking: Some providers bind access to a specific device's MAC address. If you've changed your router, your internet may not work.
• 📶 Channel congestion: If more than 10 devices are connected to the router, it may “forget” to distribute the Internet to new clients.
• 🔄 NAT failure: This results in devices receiving an IP address but not being able to access the Internet.
• 🛡️ Firewall or parental control: Access blocking for new devices may be enabled in the router settings.

Diagnostics and solutions:

1. Reboot your router: Unplug the device for 30 seconds, then plug it back in. This will reset the DHCP and NAT cache.
2. Check your WAN settings:

   Go to your router's web interface (usually 192.168.1.1 or 192.168.0.1).
   Go to the WAN/Internet section.
   Make sure that your connection type meets your provider's requirements (Dynamic IP, PPPoE, L2TP, etc.).
   If you are not sure, call your provider's support team.

3. Disable the firewall: Find the section in your router settings Security → Firewall and temporarily deactivate it.
4. Check the list of connected devices: In the section DHCP → Client List make sure yours Xiaomi Redmi is present in the list and has a correct IP.

5. Conflict with applications: VPN, antiviruses and "optimizers"

Many users install on Xiaomi Redmi Apps for speeding up the internet, blocking ads, or protecting traffic. Paradoxically, these programs are often the cause of internet outages. The most problematic ones are:

• 🔒 VPN clients: NordVPN, ProtonVPN, 1.1.1.1 (even when turned off, they can block traffic).
• 🛡️ Antiviruses: Avast, Kaspersky, 360 Security — often interfere with network settings.
• ⚡ Optimizers: DU Speed Booster, Clean Master — may reset DNS settings.
• 📵 Ad blockers: AdGuard, Blokada - sometimes all traffic is blocked due to a failure.

How to diagnose and fix:

1. Start your phone in safe mode:

   Press and hold the Power button → Advanced → Safe mode.
   Only system apps work in this mode. If Wi-Fi works, one of the installed apps is to blame.

2. Check app permissions: Go to Settings → Apps → Permissions → Networks and disable internet access for suspicious programs.
3. Reset VPN settings: IN Settings → Connections → VPN delete all saved configurations.
4. Remove "optimizers": Apps like Clean Master They often leave behind traces in the system. After deleting, reboot your phone.

⚠️ Attention: If you use AdGuard or Blokada with a local VPN, try disabling the function HTTPS filtering in the app settings. It may conflict with MIUI certificates.

6. Hardware problems: when the phone itself is to blame

If all software methods have been tried, but Xiaomi Redmi If your device still connects to Wi-Fi without internet access, there may be hardware issues. The most common ones are:

Typical hardware reasons:

• 📡 Damage to the Wi-Fi module: After a fall or exposure to moisture, the antenna contacts may oxidize.
• 🔋 Motherboard failure: problems with the Wi-Fi chip power supply (for example, a burnt-out capacitor).
• 🔌 Poor antenna contact: If the phone was dropped, the antenna cable could come off the board.

How to diagnose:

1. Check Wi-Fi operation in the engineering menu:

   Dial in your phone dialer: ##4636##
   Go to the "Wi-Fi information" section.
   Check the "Wi-Fi status" parameter. If it shows "Disconnected" despite being connected, the problem is with the module.

2. Test with another router: Try connecting your phone to a different network (such as a mobile hotspot). If the problem persists, the phone is to blame.
3. Heating check: While trying to connect to Wi-Fi, touch the top of the phone (where the antenna is located). If it gets very hot, there may be a problem with the module.

Solutions:

• 🔧 Reflashing the radio module: Sometimes flashing a separate file helps modem.bin through Fastboot.
• 🛠️ Repair at the service center: If the contacts or the board are at fault, soldering or replacement of the module will be required (cost - from 1,500 to 3,500 rubles).

Is it possible to repair a Wi-Fi module yourself?

Theoretically, yes, but only if the problem is a disconnected antenna cable. To do this, you need to:

1. Disassemble the phone (risk of damaging the display or battery).

2. Check the fastening of the antenna wires to the motherboard.

3. Solder back if the contacts have come loose.

For other faults, professional equipment is required (soldering station, microscope).

7. Problems with your provider: how to check and what to do

Sometimes it's not your phone or router that's to blame, but your internet provider itself. For example, if you have dynamic IP, and your provider has temporarily blocked your current address due to suspicious activity. Or if there's a line outage, but technical support hasn't yet reported it.

Signs of problems on the provider's side:

• 🌍 The Internet is not working on everyone devices connected to the router.
• 📞 The provider's personal account shows the status "Connected," but there is no traffic.
• 🔄 After rebooting the router, the Internet appears for 1-2 minutes, then disappears again.

How to check and fix:

1. Call your provider's support: Ask if there are any failures on your line or MAC/IP blocking.
2. Check your balance: Sometimes providers disconnect the Internet when the balance is zero or negative, but do not send notifications.
3. Change the MAC address of the router: Some providers bind access to a device's MAC address. If you've changed your router, your internet may not work. Find the option in your router settings. Clone MAC Address and clone the MAC of the old device.
4. Check your connection type: Make sure that the correct WAN type is specified in the router settings (for example, PPPoE with login/password, if required by the provider).

⚠️ Attention: If the provider uses technology Double NAT (For example, Beeline or MTS in some regions), try enabling the option in your router settings Use DNS from ISP (use provider's DNS).
