Why the hotspot on Xiaomi phone doesn’t work: a full analysis of problems and solutions

Introduction: When a smartphone refuses to give away the Internet

You try to connect a laptop or tablet to a hotspot on Xiaomi, but the devices stubbornly do not see the network, and the status proudly flaunts the words "Error to turn on the hotspot"? Or the network appears, but the Internet through it does not work, and connected gadgets get limited access? This problem is familiar to many owners of Redmi, Poco and Mi smartphones - especially after updating MIUI or changing SIM- cards.

80 percent of the time, the malfunction is not due to hardware failures, but to software failures or incorrect settings. We analyzed hundreds of user complaints on the 4PDA and Mi Community forums, tested the solutions on 15 models (from the Redmi Note 10 to the Xiaomi 14 Ultra), and identified 10 key reasons why the access point may not work. In this article, only proven ways to restore functionality, including hidden MIUI settings and circumventing carrier restrictions.

Warning: if you use a two-sim smartphone, the problem may lie in the conflict of slots – this will be discussed in detail in the section about SIM- cards. and owners of devices with MIUI 14+ should pay attention to the new limitations of background traffic, which Xiaomi has added “to save battery”.

1.Basic check: 5 steps before a deep diagnosis

Before digging into MIUI settings or calling for support, follow simple steps that solve the problem 30% of the time:

• 🔄 Reboot your smartphone. Yes, it's trivial, but once you reboot, the WifiHotspotService and ConnectivityService system services restart, which often eliminates temporary glitches.
• 📶 Check the mobile Internet. Make sure the phone is running a mobile network on its own (open the site in your browser). If there is no Internet, there is a problem with the carrier or with the SIM- card.
• 🔗 Disable VPN/ proxy. Services like 1.1.1.1 or Psiphon can block traffic to connected devices.
• 🛜 Change the Wi-Fi range. In the hotspot settings (Settings → Access Point → Setup), try switching from 2.4 GHz to 5 GHz or vice versa.
• 📱 Check the traffic limit. Some carrier rates (like Tele2 or Yota) block the distribution of the Internet after the high-speed packet is exhausted.

If the access point doesn't work after this manipulation, move to the next section, and for those who use custom firmware (such as Pixel Experience or LineageOS), we advise you to immediately scroll to the point about build.prop, which often hides the root of evil.

2 MIUI settings: Hidden access point settings

MIUI hides some of the Internet distribution settings that can block the function. For example, in firmware based on Android 13/14, the default activated traffic saving mode for background applications, which cuts the speed of the distribution to 0.5 Mbps.

1. Open Settings → SIM- Maps and Mobile Networks → [Your SIM] → Access Point]
2. Switch to Access Point Settings (or additionally in older versions).
3. Find the Speed Limit (or Traffic Saving) item and turn it off.
4. In Security, select No for the MAC- address protection option (sometimes this interferes with device connectivity).

Another pitfall is the automatic shutdown of the access point when you're inactive. In MIUI 14, the default timer is 5 minutes, after which the handout is turned off.

1. Go to Settings → Battery and Performance → Battery Mode.
2. Select the Performance profile (this will remove all background restrictions).
3. Return to the access point settings and turn off the Auto Disconnect option.

If the network is still not distributed after this, check if the Application Permits prohibit the use of mobile data for the com.android.hotspot2 system process.

3.Problems with SIM-map-and-operator

Mobile operators don't like it when subscribers distribute the Internet to other devices, some (like MTS or Beeline) actively block this feature at the network level, while others (like MegaFon) just limit the speed to 64 Kbps, making the distribution useless.

If your carrier is blocking the distribution, try changing the APN hotspot:

1. Open the Settings. → SIM-maps and mobile networks → [Yours. SIM] → Access points (APN).
2. Create a new APN with settings: Name: Internet APN: Internet.mts.ru (or Internet.beeline.ru, etc.) Proxy: not specified Port: not specified Username: not specified Password: not specified Authentication type: PAP or CHAP Type APN: default,supl,dun
3. Save and select a new APN.

To bypass the locks of the operator, you can use VPN- service (for example, ProtonVPN or Warp from Cloudflare). Connect VPN on your smartphone, then turn on the access point - traffic will go through an encrypted tunnel, and the operator will not be able to block it.

4. Conflicts with dual-sim smartphones

If your Xiaomi supports two SIM- cards, the problem may be a conflict of slots. MIUI by default prioritizes the first slot (SIM1) for distribution of the Internet, and if it is a card without mobile Internet (or without money), the access point will not turn on.

• 🔀 Change the SIM- cards. Move the Internet card to the SIM1 slot.
• 📡 Select the slot manually. In the hotspot settings (Settings → Access Point → Mobile data), specify which SIM to distribute the Internet from.
• 🚫 Turn off the second SIM. Sometimes conflict arises from trying to use both cards at the same time. Turn off the second SIM in Settings → SIM- cards.

Some models (e.g. Redmi Note 12 Pro+) have a bug: if the SIM2 slot has a Tele2 card, and the SIM1 MTS, the distribution only works through Tele2, even if you have selected the MTS in the settings. This is due to the prioritization of networks in modem_config.

1. Install the MTK Engineering Mode app (for MediaTek processors) or Qualcomm QPST (for Snapdragon).
2. Go to Engineering Mode → Connectivity → SIM Switch.
3. Manually specify the priority for the slot with the desired SIM- card.

Important for owners of Xiaomi 13/14 series: these models use a new modem management system QMI, which can reset the settings of the access point after rebooting. If the handout stopped working after the update, reset the network settings (Settings → System → Reset → Network settings Reset).

5. Firmware failures and system bugs

After MIUI updates (especially major ones like the switch from MIUI 13 to 14), the access point often stops working because of:

• 🐛 bugs in the Android kernel (e.g., the tethering_entitlement bug in Android 13).
• 🔧 Incorrect permissions for system applications.
• 📦 Conflicts with Google Play Services (especially on firmware for the Chinese region)

The first thing to do is to clear the cache of system applications:

1. Go to Settings → Applications → Application Management.
2. Find and open the settings (cog icon).
3. Press Warehouse. → Clear the cache.
4. Repeat for Phone and SIM Card applications.

If that doesn’t work, try resetting your network settings (not to be confused with a full reset!):

1. Settings → System → Reset → Network settings reset.
2. Confirm the action and restart the phone.
3. After restarting, reset the access point.

For advanced users: If the distribution stopped working after the update, check the file /system/build.prop for the presence of a line:

tether.dun.required=0

If you don't have one, you can manually add it through ADB or Root Explorer, which cancels the operator's license check.

💡

Before resetting your network, save your Wi-Fi passwords! After reset, all the saved networks will be deleted. To restore them, you can use a backup through Settings → Google → Backup.

Hardware malfunctions: when iron is to blame

If the software methods didn't work, the problem could be the hardware, and most of the time, it's the fault of:

• 📡 Wi-Fi antenna module (especially after falls or moisture).
• 🔌 Contacts SIM- cards (oxidation or pollution).
• 🔋 Power controller (inadequate voltage on the communication module).

Checking hardware serviceability can be as follows:

1. Wi-Fi antenna test: Install the WiFi Analyzer application. Look at the signal level (dBm) next to the router. If the value is lower than -70 dBm, the antenna is damaged.
2. SIM- Contact Check: Get the SIM- card and check the contacts on your phone and card. If there is oxidation, clean gently with a lasticle or alcohol.
3. Diagnostic modem: Enter ##4636##. Select phone information and see the status of Mobile network type. If there is unknown, there is a problem with the modem.

If you suspect a hardware malfunction but don’t want to carry your phone to the service, try a temporary bypass:

• 🔄 Use the USB- distribution (includes in Settings → Access Point → USB- modem) It works through a different controller and can be accessed even if the Wi-Fi module is broken.
• 🔗 Connect to your phone via Bluetooth and turn on the handout via Settings → Devices → Bluetooth → [Your Device] → Access Point.

⚠️ Warning: If your phone falls or gets wet, don't try to disassemble it yourself! Xiaomi uses adhesive joints and brittle plumes - unprofessional repairs can make the problem worse. Contact an authorized service center (listed on mi.com).

7. Alternative ways of distributing the Internet

If the standard access point is not working hard, you can use bypass methods:

• 🌐 Reverse Tethering (distribution through the USB): Connect your phone to the PC by USB. Turn on Debugging. USB (Settings → The phone. → Version. MIUI — slip 7 once, then settings → Additionally. → For developers. On a PC, install it. ADB Adb shell settings put global settings tether_dun_required 0 adb shell svc wifi enable adb shell svc tether wifi enable

Distribution annexes

• PdaNet+ bypasses the locking of operators.
• ClockworkMod Tether – does not require root, but only works on older versions of Android.
• NetShare creates a VPN- tunnel for distribution.

External Wi-Fi adapter

• Connect a USB-Wi-Fi adapter (e.g. TP-Link TL-WN725N) to your phone via OTG.
• Install DriveDroid to mount the image with drivers.

For owners of Poco F3/F4/F5 and Xiaomi 11T/12T, there is another life hack: these models support Wi-Fi Direct Hotspot, which runs more stable than a standard access point.

1. Activate Developer Mode (as described above).
2. Enable Wi-Fi Direct in Settings → Connections → Wi-Fi → Wi-Fi Direct.
3. Connect the device via Wi-Fi Direct, then manually turn on the distribution of mobile Internet.
