The pace of life often dictates its conditions, and access to the global network becomes necessary at the most unexpected moment. When a laptop lost wired Internet and the router is not available, many users know. In such cases, a smartphone with an Android operating system and a MIUI shell or HyperOS becomes the perfect salvation, turning into a full-fledged wireless router.
Owners of Xiaomi, Redmi and POCO devices have access to flexible mobile hotspot setting tools, which allow you to instantly organize a Wi-Fi connection between your phone and your computer, ensuring stable data transfer. However, despite the apparent simplicity, the process has its own nuances that affect the speed and security of the connection.
In this article, we will discuss in detail the algorithm of actions for activating the modem modem, consider the hidden power saving settings and answer frequent questions that arise when organizing a local network. The correct configuration of parameters will allow you to avoid communication interruptions and excessive battery consumption.
Activation of the access point in the MIUI interface
The first step to establish a wireless network is to log in to your device's system settings. The standard path that is relevant for most current firmware versions is in Settings → Wi-Fi Access Point, where the user accesses basic switches and security settings.
After you go to the menu, you need to activate the Wi-Fi Access Point slider. The system will automatically prompt you to set the network name (SSID) and password if this is the first time, and it is recommended to immediately change the standard device name to a more recognizable one, so as not to get confused when searching for a network on a laptop.
In modern models of smartphones, the option of switching between 2.4 GHz and 5 GHz is available. The choice of 5 GHz frequency will provide a higher data rate, but the signal range will be somewhat smaller, and compatibility with older Wi-Fi modules in laptops may not be available.
💡
Use the 5GHz band only if your laptop is in close proximity to your phone (up to 3-5 meters), as these waves are worse at penetrating walls and obstacles.
Remember that activating the Internet automatically turns off Wi-Fi on the smartphone itself, switching it to mobile data transfer. This is standard behavior of the Android operating system, which can not be circumvented by software methods without using third-party root-rights utilities.
Set up security and network parameters
The security of the network being created is a critical aspect, especially if you are in a public place. Xiaomi access point settings use the WPA2-Personal encryption protocol by default, which provides reliable protection of transmitted data from interception.
The password must be complex enough to prevent brute-force matching, allowing for combinations of letters and numbers up to 32 characters long, and avoid using simple sequences or dates of birth, as this makes your network vulnerable.
- 🔒 Use a mixed register of letters and special symbols to enhance protection.
- 📡 Change your password regularly if you have access to the network by third parties.
- 👀 Follow the list of connected users in the access point menu.
- ⚙️ Turn it off. WPS, If this option is available in the extended settings.
In the advanced settings, the Hide Device feature is also available. When you activate this option, your phone will not broadcast the network name on the air. To connect your laptop, you will need to manually enter SSID in the list of available Windows or macOS networks.
What does the SSID coverup do?
Connected device limits are another useful control tool, and you can limit the number of gadgets that can access the Internet at the same time, which will prevent congestion and reduce the load on the smartphone processor.
Energy saving and stability of connection
One of the main problems in the distribution of the Internet is the aggressive policy of energy saving the shell MIUI. The system can automatically turn off the access point if it believes that no one is using it, or to save battery power, even if the connection is active.
To avoid connection breaks, you need to enter an access point in the optimization system exceptions. Go to the Security menu → Battery → Settings and find the item responsible for sleep behavior. Make sure that the access point service is selected “No restrictions”.
Also, check the settings of the individual application responsible for the modem. In the list of installed applications, find the system component "Access Point" and in the "Energy Saving" section, select "No restrictions" mode, which will prevent the system from "sleeping" the Wi-Fi module.
💡
Turning off energy savings for the access point is a must for the Internet to work on a laptop for a long time.
Wi-Fi Internet connectivity significantly increases power consumption. The phone can get hot, especially when using 4G/5G networks with high download speeds. It is recommended to keep the device connected to the charger or put it on a cold surface for better heat sink.
Solving Connection Problems on Laptop
Sometimes a laptop sees a network but can't connect, or it's connected and the Internet doesn't work. IP-addresses or settings DNS. First of all, try on a laptop to perform a command to reset network settings or just “Forget the network” and connect again.
If your laptop says "No Internet access," check if the mobile Internet is activated on the smartphone itself. Sometimes, once the hotspot is turned on, the data doesn't switch automatically. Also, make sure you have a balance or a traffic limit is not exhausted.
In rare cases, a change in type helps. APN in the mobile network settings. Go to Settings → SIM-maps and mobile networks → Access points (APN). Make sure you have the right profile for your operator, and you can try creating a new hotspot with the standard operator settings.
⚠️ Note: If you change your settings APN, Write down the initial settings. Incorrect settings can cause a total loss of mobile Internet before resetting the network settings.
Another reason may be static. IP-The address on the laptop, make sure that the protocol properties IPv4 Windows is automatically receiving IP-addresses DNS-server.
Comparison of Distribution Methods: Wi-Fi, USB and Bluetooth
There are several ways to transmit the Internet, and the choice depends on the specific tasks and equipment available. Wi-Fi is the most popular due to its versatility and lack of wires, but it is not without the disadvantages of heating and energy consumption.
Distribution through USB-The cable provides the most stable connection and charges the phone at the same time, which is ideal for stationary work behind a laptop, because it eliminates speed losses due to radio interference and provides maximum channel bandwidth.
Bluetooth modem is the slowest option, and it only makes sense to use it in extreme cases, when other methods are not available, and you only need to transfer text data. 1-2 Mbit/s.
| Parameter | Wi-Fi Access Point | USB-modem | Bluetooth modem |
|---|---|---|---|
| Transmission speed | High (up to 100+ Mbps) | Maximum (stable) | Low (up to 2 Mbps) |
| Battery consumption | High-pitched | Charging the phone | Medium. |
| Number of devices | Up to 10 (depending on model) | 1 | 1 |
| Stability | Depends on the interference. | Tall. | Low. |
For gamers or those who work with large amounts of data, it is definitely recommended to use the USB-It guarantees minimal ping and no speed jumps, which is critical for online broadcasts or video conferencing.
Optimizing traffic and controlling costs
When using a smartphone as a router, it is important to control the amount of traffic consumed, especially if you have an unlimited tariff. In the settings of the Xiaomi access point, there is a “Traffic Limit” function that allows you to set a threshold after which the distribution of the Internet will automatically cease.
It is recommended to set a limit slightly less than your actual monthly volume to have a margin. For example, if you have 30 GB, set a limit of 25 GB. This will save you from unexpected write-offs by the operator.
- 📉 Turn off automatic Windows updates on your laptop when working over a mobile network.
- 🎥 Reduce the quality of videos on YouTube and streaming services to 720p or 480p.
- 💻 Close background applications that consume traffic (torrents, cloud syncs).
- 📊 Regularly check the statistics of data usage in the menu of the access point.
☑️ Checking before a long session
MIUI also allows you to view the traffic detail of your connected devices, so if you notice that one of your devices is consuming an abnormal amount of data, you can block it right from the access point control menu.
