Modern smartphones Xiaomi, Redmi And POCO They've long ceased to be mere devices for making calls, becoming full-fledged multimedia centers and work tools. In situations where landline internet is unavailable or the provider has experienced a failure, the ability to quickly transform your gadget into a portable router becomes critical. This feature, known as mobile hotspot, allows you to share mobile traffic with laptops, tablets, or phones of colleagues and friends without using wires.
The process of activating distribution on devices with a shell MIUI or HyperOS The interface may differ from standard Android due to its extensive customization. Users often encounter network issues with other devices not detecting the network, or with the connection dropping after a few minutes. In this article, we'll cover in detail how to properly configure security settings, select the optimal frequency, and avoid common mistakes that lead to increased battery consumption.
It's important to understand that sharing the internet is a resource-intensive operation that affects not only the battery charge but also the processor's temperature. Properly adjusting the parameters AP client This will help minimize heat and ensure stable connection speeds for all connected devices. Below, we'll walk you through all the necessary settings step-by-step.
Basic activation of the access point via the curtain and settings
The fastest way to activate tethering is to use the control panel, which is accessed by swiping down from the top of the screen. In the quick actions list, find the "Tethering" icon (usually looks like an antenna with a signal). However, this method activates the feature with default settings, which may not be optimal for your situation, such as using an outdated encryption standard or a weak password.
For more detailed control, go to the deep system menu. Open Settings, then select the section Connection and sharing (In some firmware versions, it may be called "More" or "Advanced"). This is where the main controls for your smartphone's network module are hidden. Find the item Wi-Fi hotspot and click on it to enter the submenu.
In this section, you'll see a service status switch. Before activating it, it's recommended to tap your network name (usually your phone model) to change the identifier. SSIDThis will hide the device's real name from prying eyes in the list of available networks. You can also set a password here, which should be complex enough to prevent neighbors from accessing your traffic without permission.
☑️ Check before starting distribution
Setting up security and network settings
The key to establishing a secure connection is choosing the right encryption protocol. In the access point settings menu, look for "Security" or "Encryption Type." By default, it's often set to WPA2-Personal, which is the optimal choice for most modern devices. Using an open network (without a password) is strictly not recommended, as all transmitted traffic can be intercepted by attackers.
Pay special attention to the frequency range. In the access point settings (often hidden under "Access point settings" or "Advanced"), you can select the frequency range: 2.4 GHz or 5 GHz. 2.4 GHz has a longer range and better penetration through walls, but it is often overloaded by neighboring routers and microwaves. The range 5 GHz It provides significantly higher data transfer rates and is less susceptible to interference, but has a shorter range.
⚠️ Attention: If you select the 5 GHz band, older laptops or budget tablets may simply not detect your network. If a connected device doesn't find the access point, try forcing it to switch to 2.4 GHz in your smartphone's settings.
You can also configure SSID hiding in this section. If you enable this feature, your network won't appear in the general list of available connections on other devices. To connect, you'll need to manually enter the network name and password. This adds an extra layer of privacy, but makes the connection process more complicated for guests.
Why hide SSID?
Hiding the network name (SSID) isn't fully secure against hackers, as the name is broadcast in service packets when authorized devices connect. However, it does protect against nosy neighbors who might try brute-force password attacks if they see an active network nearby.
Managing connected devices and limits
shell MIUI Provides convenient tools for monitoring who uses your internet. The access point menu often displays a list of connected clients with their MAC addresses. You can block an unknown device at any time by simply clicking on it and selecting the appropriate action. This is especially useful in public places, where brute-force password attacks are theoretically possible.
To save data and battery life, there's a "Data Limit" feature. You can set a data limit (for example, 1 GB or 5 GB), after which data sharing will automatically turn off. This prevents unpleasant surprises on your phone bill at the end of the month if you forget to turn off your hotspot after downloading a large file on your tablet.
You can also configure a sleep timer. You can set the hotspot to turn off if no device is connected for 5 or 10 minutes. This prevents your phone from heating up and wasting power while waiting for a connection that won't happen.
| Parameter | Recommended value | Impact on work |
|---|---|---|
| Frequency range | 5 GHz (for speed), 2.4 GHz (for compatibility) | Signal speed and range |
| Encryption | WPA2-Personal | Protecting data from interception |
| Max clients | 4-6 devices | Distribution speed stability |
| Sleep timer | 5 minutes | Saving battery life |
Sharing the Internet via USB and Bluetooth
It's not always convenient or possible to use a wireless connection. In some cases, maximum stability or minimal latency (ping) is required, which is important for online gaming or video calls. In such situations, USB modemTo activate it, connect your phone to your computer using a cable, then select "USB Modem" in the "Connection and Sharing" menu. The system will automatically install the necessary network drivers, and the computer will treat the phone as a wired Ethernet connection.
The advantage of USB hotspot is that it simultaneously charges your smartphone. While the battery may drain faster than it charges when connected to a Wi-Fi hotspot, especially when using powerful adapters, a USB connection guarantees a stable power supply. Furthermore, a wired connection eliminates the risk of radio signal interception.
The third option is distribution through BluetoothThis method is the slowest and is only suitable for text messaging or emergency email when other options are unavailable. To activate, you need to pair the devices, then enable "Bluetooth tethering" in your phone's Bluetooth settings. Speeds rarely exceed 1-2 Mbps, which is insufficient for comfortable video viewing.
Network visibility issues and solutions
A common problem for users Xiaomi And Redmi The problem is that the laptop or other phone simply doesn't see the access point you've created. One of the main reasons is the 5 GHz band mentioned above. Many older network cards simply don't support this standard. There's only one solution: force the access point to use the 2.4 GHz band in its settings.
The second reason could be region. Some countries (for example, Japan) have legally restricted Wi-Fi channels, and if the "Japan" region is selected in the phone settings, some devices may not see the network or may see it but not connect. Check the region settings in the menu. Settings → Additional settings → Region and set your country or neutral region (for example, USA or Russia).
It's also worth checking whether the "Data Saver" or "Modem Mode" feature is enabled in your SIM card settings. Some data plans prohibit tethering. Your carrier may block your connection or throttle your speed if it detects you're tethering (this is determined by the TTL value). In such cases, changing the TTL value in your system settings can help, but this requires more advanced knowledge and may violate your contract with your carrier.
⚠️ Attention: If you've changed the frequency or region settings, be sure to turn the access point off and on again. Changes will only take effect after restarting the hotspot service.
Energy optimization and overheating
Sharing Wi-Fi is one of the most power-hungry tasks on a smartphone. The radio operates at maximum power, the processor actively processes network packets, and the screen (if on) also consumes power. All this leads to rapid heating of the device. If the phone is exposed to direct sunlight or in a case with poor heat dissipation, the system may automatically disable the access point to protect its components.
To minimize heat buildup, try not to leave the screen on while sharing. Set the screen timer to 30 seconds or 1 minute. It's also recommended to remove any protective case if you plan to use the modem for extended periods. Ideally, place the phone on a cool surface (stone, metal, glass), but not on a soft cloth or sofa.
In the battery settings MIUI You can check if background activity is restricted for network system processes, although the system usually prioritizes this process automatically. However, if you have "Ultra Power Saving Mode" enabled, Wi-Fi hotspots may be blocked or unstable. Make sure this mode is disabled.
Frequently Asked Questions (FAQ)
Why does the laptop see the network but not connect to it?
The issue is most likely due to incompatibility between encryption standards or frequency bands. Try changing the security type to WPA2 PSK and switching the band to 2.4 GHz. Also, check if the list of allowed devices is full if you have a limit on the number of clients.
Is it possible to share Wi-Fi if my phone is out of money but I have social media packages?
Technically, it's possible to share your internet, but it will only work within the limits of the apps allowed by the operator (free traffic). However, many operators block the ability to create a hotspot when using plans with unlimited social media, requiring payment for the full plan.
How do I know who is connected to my hotspot?
Go to the hotspot settings on your Xiaomi phone. There should be a "Connected devices" section or a list of clients. In newer versions of MIUI, this information may be hidden for privacy reasons, so all you have to do is change the password and monitor your data usage.
Does Wi-Fi sharing affect the speed of mobile internet on the phone itself?
Yes, it does. The connection is shared between the phone and connected clients. If the laptop starts downloading a large update, the page loading speed on the smartphone itself will also drop, as the radio module operates in half-duplex mode.
