When a WiFi hotspot on a Xiaomi smartphone suddenly stops working or issues an error when trying to connect other devices, it is a common problem for users. MIUI And HyperOS, which is most often due to a frequency band conflict or a software failure in the communication module, users may see that the gadgets simply do not see the network, or the connection is terminated immediately after receiving the device. IP-address.
Owners of Redmi and Poco devices often find that the system blocks modem launch due to operator limitations or incorrect APN settings. In some cases, the problem lies deeper, affecting system configuration files of the network. Understanding the nature of the failure allows you to quickly return functionality to the device without going to the service center.
First, you need to rule out trivial reasons, such as lack of mobile traffic or flight mode on. If the network indicators work normally, but Internet distribution is impossible, you need to perform a number of specific actions to reconfigure the parameters of the wireless interface. Next, we will look at the detailed algorithms of the solution.
Diagnostics and primary network settings
The first step is always to check the basics, make sure that the SIM card has an active packet of Internet traffic and it is actually consumed when you connect directly, often because the data limit is exhausted, and the operator blocks the ability to share the Internet.
Then you should check the settings of the modem mode itself. Go to Settings → Wi-Fi Access Point. It is important to pay attention to the frequency range here. If you are trying to connect an old device that does not support 5 GHz, and you choose this range, the connection will not happen.
⚠️ Switching to 2.4GHz may reduce the maximum data rate, but will significantly improve compatibility with older laptops and tablets.
It's also worth checking if there's a traffic limit for the hotspot itself, and there's a restriction option in the handout settings that automatically shuts down Wi-Fi after you've consumed a certain amount of data, and if that limit has been reached before, the feature may not start again without manually resetting the meter.
Make sure that the device does not include energy-saving modes that can block the operation of the background services of the network. Aggressive battery optimization in MIUI sometimes “kills” the process of distributing WiFi immediately after turning off the screen of the smartphone.
Compatibility of 2.4 GHz and 5 GHz bands
One of the most common reasons why other devices don’t see the Xiaomi hotspot is the incompatibility of standards: Modern smartphones default to a 5GHz network to provide high speeds. However, many older laptops, gaming consoles and budget gadgets are physically unable to work with this frequency.
To fix this, you have to force the broadcast standard to switch, go to the access point settings and find "Frequency Range" or "AP Band." Select 2.4 GHz, and then the network will be visible to a wider range of devices, although the speed may be lower.
It is important to understand the differences: 2.4 GHz has better penetration through walls, but is more prone to interference from neighbouring routers and microwave ovens. 5 GHz is cleaner and faster, but the range is shorter. For distribution of Internet from a phone in one room, 2.4 GHz is often the best solution because of maximum compatibility.
If the error persists after the range change, try changing the broadcast channel. In the advanced settings, you can choose a specific channel instead of "Auto". Often channels 1, 6 or 11 are the most stable in the noisy air.
Resetting network settings and re-registration in the system
If simple switching didn’t work, a deeper reset of network settings is required, which will return all Wi-Fi, Bluetooth and mobile internet settings to factory values by removing stored passwords and APN configurations. This often resolves a problem when an error is caused by a software conflict.
To perform the procedure, follow the Settings path → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. The system will warn you that all stored networks will be forgotten. Confirm the action and wait for the network modules to restart.
☑️ Checklist before network reset
Once reset, you need to reconfigure the access point. Specify a new network name (SSID) and a complex password. Sometimes the system can't run a hotspot with settings that were corrupted before reset, so creating a "from scratch" configuration is key.
In some cases, the relocation helps. SIM-cards to another slot (if there are two) or temporarily retrieving the card and then installing it back, which forces the communication module to re-register in the operator's network and update the service profile, which can remove the blocking on the distribution of traffic.
APN settings and operator parameters
Operators often use APNs to charge traffic. If the APN settings are incorrect or have errors, the Internet on connected devices will not work even if the Wi-Fi connection is installed. The "No Internet access" error most often lies here.
Check the current settings can be in the Settings menu → SIM-maps and mobile networks → Choice SIM-map → Access points (APN). Make sure your operator’s active access point is selected. If the list is empty or the settings are lost, click the reset button on the default settings (usually a menu icon or three dots).
| Parameter | Value for most operators | Note |
|---|---|---|
| Name | Internet (or operator name) | arbitrary name |
| APN | internet | Key parameter, register is important |
| Proxy | (empty) | Do not fill in without the operator's instructions |
| Port port | (empty) | Don't fill in |
Pay special attention to the field APN. For most Russian and European operators, it should contain the word Internet in the lower case, the presence of spaces, capital letters or extra characters can lead to the denial of data services.

Update the system and reset to factory settings
WiFi issues are often software-based and are patched by developers in security updates. If you have an older version of MIUI or HyperOS installed, the chances of driver conflicts are higher. Check for updates in the Settings → About Phone menu.
Sometimes updating the system doesn’t solve the problem right away because the old configuration files are stored in memory, in which case a full hard reset is an effective but radical method.
Performance of discharge:
- 📱 Go to Settings. → The phone. → Resetting settings.
- 🗑️ Select "Erase all data".
- 🔒 Enter the screen unlock password to confirm.
- ⏳ Wait for the process to be completed and the initial setup.
⚠️ Warning: Full reset will delete all photos, contacts and apps. Make sure you have an up-to-date copy of the data before starting the procedure.
Even if the access point is running faulty after a clean installation of a system without third-party applications, it may indicate a hardware fault in the WiFi module, in which case the software methods are powerless and a diagnostic service center is required.
Third-party applications and bypassing locks
Some users try to use third-party apps from Google Play to create an access point if a standard Xiaomi feature is blocked by an operator. Apps like PdaNet+ or WiFi Hotspot can use other methods of networking, bypassing system restrictions.
However, these programs have their own risks: they require extensive network access permissions and can consume significantly more battery life than the built-in solution, and they are not always stable on newer versions of Android due to changes in security policies.

If the built-in access point does not work, try to distribute the Internet through the Internet USB-Connect your phone to your PC, select from the menu. USB "USB-Modem – This is often more stable and doesn’t consume battery as quickly.
It is also worth mentioning the possibility of using ADB-commands for hidden settings, if you're an advanced user. For example, you can try changing the hidden wifi.tethering.formfactor setting, but that requires a computer connection and debugging. USB.
The command to change the type of device through ADB (requires caution):
