Before resetting settings, untie the Mi Account from the phone, otherwise after reset, you will need to enter a password from the old account, which could be linked to another number.

4. Wi-Fi issues: from router to phone settings

If mobile internet works and Wi-Fi doesn't, either the router or Xiaomi's settings are to blame.

• 🔌 The phone connects to Wi-Fi, but the pages don't load (Wi-Fi icon is active, but there's an exclamation mark nearby).
• 🔄 Wi-Fi is periodically switched off or reconnected.
• 🚪 Some sites open and others don’t (for example, VKontakte works, but YouTube doesn’t load).

Diagnosis by step:

1. Check the router: - Reboot the router (remove the plug from the socket for 30 seconds). - Make sure that the router is on the Internet indicator (usually blue or green). - Try connecting another device (laptop, tablet) to this Wi-Fi. If the Internet does not work and there - the problem is in the router or provider.
2. Wi-Fi settings on Xiaomi: - Forget the network: Settings → Wi-Fi → [Your network] → Forget, then connect again. – Disable Smart Switching (in the same Wi-Fi settings) – this feature often fails on the Internet. MIUI 14+. - Check if the data restriction is worth it: Settings → Wi-Fi → [Your network] → Data limitation.

If Wi-Fi is working but the speed is extremely low (e.g. 1 Mbps instead of 100 Mbps), check:

• 📶 Is the router channel overloaded (try switching to 5GHz in the router settings).
• 🔒 Is the speed limit worth it in the router settings (sometimes it is done by "caring" parents).
• 📱 Is the traffic saving mode on Xiaomi included: Settings → Battery and performance → Traffic saving regime.

💡

If your Xiaomi doesn't see a 5GHz Wi-Fi network, upgrade the router's firmware. on some models (e.g. Redmi). 9A) 5GHz support only comes after update MIUI before version 12.5+.

5. Blocking by the operator: restrictions, debts, technical works

Mobile operators may restrict Internet access for several reasons, and this is not always obvious.

• 💰 Unpaid bill (even if the balance is positive, sometimes a block for late payment is triggered).
• 📵 Exhausted traffic (on unlimited tariffs after exceeding the FUP The speed drops to 64 Kbps, making the internet unusable).
• 🔒 Technical limitations (e.g. roaming in a region where the operator does not provide data).
• 🆔 Lockdown IMEI (If the phone is listed in the database of stolen or uncertified devices).

How to check:

1. Call the operator's short number: - MTS: *111# - Beeline: *102# - MegaFon: *105# - Tele2: *155# In the automatic menu, select "Balance and tariff" or "Service status".
2. Check it out. SMS from the operator – sometimes a notification comes when blocking (but it can get lost among spam).
3. Put it in. SIM If the Internet doesn't work there, the operator's problem is certain.

• 📧 Write a complaint to the support mail (addresses are usually on the operator’s website).
• 🔄 Try to re-release. SIM-card (sometimes helps in case of failures in the operator's database).

⚠️ Note: Xiaomi phones purchased overseas (e.g. global Redmi versions for India) may not work LTE in Russian networks due to differences in supported frequencies.

Hardware malfunctions: from antenna to motherboard

If all the software methods have been tried and the Internet still doesn't work, the problem could be hardware.

1. Check your fall history: If your phone falls or gets wet, it’s likely that your contacts are the problem.
2. Test in Safe Mode: - Turn off the phone. - Press the power button, and when the Xiaomi logo appears, press and hold Volume down until the phone boots. - Safe Mode disabled all third-party applications. If the Internet is working - a problem in the software, if not - in the hardware.
3. Diagnostics via engineering menu: - Dial ##4636##. - Select Phone Information. - See the network status: if the Service State section says Out of service - the problem is in the communication module.

If the diagnosis confirmed a hardware malfunction:

• 🔧 Contact the authorized Xiaomi service center (the list is available on the website mi.com).
• 💰 Check the cost of repair: replacing the antenna costs 1.5-3 thousands of rubles, and the replacement of the motherboard can cost up to 70% phone price.
• 📱 If the phone is warranty, do not open it yourself - this will cancel the warranty!

💡

On Xiaomi models with a metal body (such as the Mi 11), antennas often depart after impacts, a sign that the Internet only works in a certain position of the phone (for example, if you tilt it at a 45-degree angle).

Annex conflicts: VPN, Antiviruses and "optimizers"

Some applications can block the Internet at a system level, and most often, the fault is:

• 🔒 VPN-Clients (e.g. NordVPN, ProtonVPN) that have not disabled correctly.
• 🛡️ Antiviruses (Kaspersky, Dr.Web) with firewall function.
• 🚀 "Optimizers (Clean Master, DU Speed Boosters that aggressively close the background processes.
• 🎮 Game cheats (such as GameGuardian) that modify system files.

How to find and resolve conflict:

1. Check it out. VPN: - Open the Settings. → VPN and disable all active connections. VPN-Applications that have not been used for a long time.
2. Turn off the firewall: In antivirus, find the Firewall or Network Screen section and temporarily turn it off.
3. Run it in Safe Mode (the instructions were in the previous section), and if the Internet is running, it's one of the apps installed that's to blame.
4. Check the permissions: - Open the settings → Annexes → Permits → Auto-Run and make sure system applications (such as Google Play Services) have the right to auto-run.

If a conflict is found, but the application is necessary:

• 🔄 Try to update it to the latest version.
• 📥 Reinstall the app (sometimes cleaning the cache helps).
• 🚫 Add it to optimization exceptions: Settings → Battery and performance → Battery optimization → Select an application → No restrictions.
