The modern smartphone has long ceased to be just a means of communication, having become a fully-fledged mobile office and entertainment center. Brand devices Xiaomi They occupy a significant market share thanks to their excellent price-to-features ratio, offering users powerful tools for working with the internet. One of the key features that owners of these gadgets use daily is the modem mode. In situations where landline internet is unavailable or there is a provider outage, the ability to quickly distribute Wi-Fi becomes critically important.
The process of activating an access point in the MIUI shell or a new one HyperOS It may seem simple, but hidden settings allow you to optimize your connection for different usage scenarios. You can configure the frequency range for maximum speed or, conversely, for better compatibility with older devices. The system also offers flexible traffic management tools, helping you avoid unexpected charges when using mobile data.
In this article, we'll cover every setup step in detail, from basic setup to advanced security and power-saving settings. Understanding these nuances will help you create a stable network even in poor signal conditions. We'll also cover common issues users encounter and effective solutions without calling a service center.
Basic hotspot activation via settings
The most common and reliable way to enable tethering is to use the default system menu. First, unlock the screen and go to the main application menu. Find the icon Settings, which usually looks like a gear, and click on it to enter the system management section of the device.
In the list of settings that opens, find the section responsible for wireless connections. Depending on your firmware version, it may be called "Connection and Sharing" or simply "Access Point." This is where all the key switches for managing your smartphone's network interfaces are located.
Click on the item Wi-Fi hotspotA page with basic network settings will open. To activate the mode, simply move the slider at the top of the screen to the active position. Your smartphone will then begin broadcasting a signal, allowing other devices to discover your network and connect.
☑️ Pre-launch check
It's important to note that immediately after powering on, the system may prompt you to select the type of device to connect or configure restrictions. Don't ignore these prompts, as they help optimize the communication module's performance. Proper initial configuration will eliminate the need for reconfiguration in the future.
Setting up a network name and security settings
By default, the system assigns a network name containing the device model, which is not always convenient or secure. It is recommended to change this immediately. SSID (Network ID) to a unique name that's easy to recognize in the list of available connections. To do this, tap the line with the current name in the access point menu and enter a new name.
Particular attention should be paid to the encryption type. In modern versions MIUI protocol is set by default WPA3-Personal or WPA2-PSKThis ensures reliable protection of transmitted data from interception. Using an open network without a password is highly undesirable, as it allows any nearby user access to your traffic.
Why can't you use WEP?
The WEP encryption protocol is considered obsolete and can be easily cracked with specialized software in a matter of minutes. Even if your device only supports this standard, it's better to update its firmware or use alternative connection methods rather than risk your data.
⚠️ Note: When you change your password, all previously connected devices will lose connection and require re-authorization with the new access key. Please notify users in advance if you share your internet connection with colleagues or family.
Password length is also important: it's recommended to use a combination of letters and numbers that's at least 8 characters long. This will make brute-force attacks more difficult in the event of an unauthorized access attempt. Save your changes by clicking the confirm button.
Frequency range selection and compatibility
One of the most important settings affecting connection speed and stability is the frequency band selection. Xiaomi hotspot menus typically offer two options: 2.4 GHz and 5 GHz. Understanding the difference between them will help you choose the optimal mode for your specific conditions.
The 2.4 GHz band is more versatile and compatible with the vast majority of devices, including older laptops, tablets, and budget gadgets. It provides good coverage and penetrates walls better, but data transfer speeds are limited, and the channel itself is often congested by neighboring networks.
The 5 GHz frequency offers significantly higher throughput, which is critical for watching 4K video, playing online games, or downloading large files. However, its range is shorter and it penetrates obstacles less effectively. Furthermore, many older devices simply won't detect a network operating in this frequency range.
| Parameter | 2.4 GHz | 5 GHz |
|---|---|---|
| Speed | Up to 150-300 Mbps | Up to 800+ Mbps |
| Range | High | Medium/Low |
| Permeability of walls | Good | Bad |
| Compatibility | 100% of devices | Modern gadgets |
If you're unsure which device you'll be connecting to, or if there are multiple devices in the same area, it's best to leave the default setting or select 2.4 GHz for a guaranteed connection. Switching between modes is instantaneous, without rebooting the communication module.
Managing connected devices and limits
Shell functionality Xiaomi Allows you to not only share your internet but also control it. The "Connected Devices" section displays a list of all devices currently using your data plan. Here you can see the device name and the amount of data transferred.
To conserve battery life and prevent bandwidth congestion, we recommend setting a connection limit. By default, the system allows up to 10 devices, but for comfortable operation with just one or two devices, it's best to limit this number. This will also improve the security of your personal network.
The traffic limit setting feature deserves special attention. You can set a maximum data volume, after which the hotspot will automatically shut down. This is especially useful for packages with limited data, as it allows you to avoid additional charges.
Some firmware versions offer a "One-Time Connection" feature, which allows guests to connect without entering a password by scanning a QR code, but with a limited session duration. This is a convenient way to share the internet without disclosing your main password.
Hiding the network and advanced settings
For privacy-conscious users, a hidden SSID feature is available. When enabled, your access point will no longer appear in the general list of available networks on other devices.
To connect to a hidden network, users must manually enter the exact network name (SSID) and password into their device's Wi-Fi settings. This creates an additional barrier to accidental connections and scans, although it is not completely secure against professional attacks.
You can also find a power-off timer option in the advanced settings. You can set the hotspot to automatically turn off if no device connects to it for a specified period of time (e.g., 5 or 10 minutes). This is a useful power-saving feature that prevents the module from running unnecessarily.
⚠️ Note: The menu interface may differ slightly depending on the MIUI version (12, 13, 14) or the upgrade to HyperOS. The layout of the options may change, but the logic remains the same for all Redmi and Xiaomi models.
Energy saving and performance optimization
Hotspot mode is one of the most power-hungry processes on a smartphone. The intense work of the radio module and the processor processing network packets leads to rapid battery drain and increased heat in the device.
System Android The MIUI interface and the phone have built-in protection mechanisms. If the battery level drops below a critical level (usually 10-15%), the hotspot can automatically disable itself to preserve emergency calling capabilities. It's recommended to keep the phone charged during extended tethering sessions.
To reduce heat buildup, avoid covering your phone with fabric or leaving it in direct sunlight while tethering. Remove any protective case if it's thick and doesn't dissipate heat well. Overheating can lead to throttling (reduced performance) and temporary Wi-Fi shutdown.
Solution: Why devices won't connect
Despite the system's stability, users may encounter situations where the phone detects the network but fails to connect, or the connection is dropped immediately after being established. This is often due to incompatibility between security protocols or frequency bands.
Try changing the encryption type from WPA3 to WPA2 if the device you're connecting to is quite old. Resetting the network settings on the device you're connecting to or restarting the Xiaomi smartphone itself also helps. In rare cases, resetting the network settings to factory defaults may be necessary.
If the problem persists, check if there's a MAC address restriction or if the number of connected users has been reached. Also, make sure the phone sharing the internet connection has mobile data enabled and has a cellular signal.
Is it possible to share Wi-Fi if the phone is connected to Wi-Fi?
Most modern Xiaomi models running Android 10 and above have a Wi-Fi Sharing feature. This allows you to receive and share internet via Wi-Fi. However, this feature must be supported by both hardware and software. On older models, when you enable a Wi-Fi hotspot, the module will switch to the mobile network.
How many devices can be connected at the same time?
Technically, a smartphone's processor and Wi-Fi module can handle up to 10 or more connections. However, the actual speed on each device will decrease proportionally to the number of clients. For comfortable use, it is recommended to limit the number of active devices to 3-4.
Does Wi-Fi sharing affect mobile internet speed?
Yes, it does. Some of the bandwidth is used for service packets and the access point itself. Furthermore, if multiple devices are connected, the total bandwidth is divided between them. Speed also depends on the 4G/5G signal strength in your location.
Is there an extra charge for distribution?
Carriers don't charge extra for simply enabling tethering. However, all data consumed by connected devices is charged according to your plan. If you have an unlimited plan, be sure to check the "fair usage" terms, as some carriers limit speeds when hotspot mode exceeds a certain threshold.
