Xiaomi, Redmi and POCO are no longer just phone calls, but powerful tools for work and entertainment. In situations where wired internet is unavailable or unstable, the ability of a smartphone to become a full-fledged router saves in a variety of scenarios. Users often look for ways to distribute Wi-Fi from Xiaomi to connect a laptop, tablet or TV to the network through mobile traffic.
Known as Wi-Fi Access Point, the feature is embedded in the MIUI and HyperOS shell at a deep system level to ensure stable connectivity. However, hidden settings and additional features often go unnoticed by the average user. In this article, we will detail the process of activating, optimizing speed and solving typical problems that arise when creating a personal network.
It’s important to understand that the Internet’s distribution affects the power consumption and heating of the device, so knowing the intricacies of the setup will help to extend battery life. We’ll look not only at the basic steps, but also at advanced parameters such as choosing a frequency range and limiting traffic for connected customers.
Basic activation of the access point in MIUI and HyperOS
The process of turning on the modem on Xiaomi devices is as simple as possible and takes only a few seconds. The fastest way is to lower the notification curtain and find the access point icon. If you can't see it in the front row, click on a pencil or edit button to drag the icon to the active area. This method is ideal for fast distribution, but does not give access to the subtle security settings.
To get deeper control, you need to go to the system menu. Open Settings, find Connection and Sharing (older versions might have called it “Additional Features” or simply “Wi-Fi Access Point”), and that’s where all the key parameters that affect connection stability and visibility of your phone to other devices are hidden.
Once you go to the menu, you'll see a switch that activates the function, immediately below it will display the network name (SSID) and default password, and it's highly recommended that you change the standard device name that contains the phone model to something neutral to avoid attracting unnecessary attention from outsiders in public places.
☑️ Checking before handout launch
It's worth noting that the interface may vary slightly depending on the version of the operating system. HyperOS has made the design more minimalistic, and security settings are made in a separate submenu for convenience. The main thing is not to confuse the Wi-Fi access point with a Bluetooth modem, since the speed of the latter is much lower and is suitable only for transferring small amounts of data.
Advanced security and visibility settings
Personal network security is the number one priority, especially when using open data protocols. In the access point settings, Xiaomi lets you choose the type of encryption. Always choose WPA2-Personal or, if client devices support, WPA3. Outdated protocols like WEP or no password make your data vulnerable to interception.
⚠️ Warning: Never leave your access point open (without a password) in public places.Attackers can intercept unencrypted traffic or use yours. IP-purport.
One of the most useful features in Xiaomi smartphones is the ability to hide the network. If you activate the Hide the Network option, your phone will stop broadcasting the SSID name on the air, you can only connect to such a network by manually entering the name and password on the client device, which creates an additional layer of protection from prying eyes.
What does the SSID coverup do?
You can also set the maximum number of devices you can connect to in this section. Although the system allows you to connect up to 10 gadgets, the real performance depends on the processor and radio module. For stable operation, it is recommended to limit the number of customers to 3-5, especially if you are in an area with a lot of other Wi-Fi networks.
Frequency range choice: 2.4 GHz vs. 5 GHz
One of the key parameters that affect signal speed and range is the choice of frequency range. In the settings of the Xiaomi access point, the option “Use the 5 GHz band” is often used. By default, it can be turned off, since the 2.4 GHz frequency has better penetration and is compatible with all devices, even very old ones.
But if you want top speed for 4K video or online gaming, switching to 5GHz will give you a noticeable boost. This range is less crowded by neighbourhood routers, which reduces interference. But remember, the 5GHz range is smaller, and the signal is worse through walls.
| Parameter | 2.4 GHz | 5 GHz |
|---|---|---|
| Transmission speed | Up to 150 Mbps | Up to 433 Mbps and up |
| Range of action | Tall. | Medium |
| Wall penetration | Good. | Low. |
| Compatibility | 100% devices | Only modern gadgets |
| Level of interference | High (microwaves, Bluetooth) | Low. |
If you don’t know which range to choose, leave the setting in Auto mode (if available) or switch manually depending on the tasks. 2.4 GHz is enough to work with documents in a cafe, and 5 GHz is better to download heavy files at home.
Saving traffic and controlling connected devices
Mobile Internet is not unlimited, so the MIUI traffic restriction function is critical, so you can set a traffic limit on the access point menu, after which the Wi-Fi distribution will automatically turn off, which saves you from unpleasant surprises in the form of a negative balance or a number lock by the operator.
It also allows you to view the list of connected devices in real time, so you can see the name of the gadget and the amount of traffic it consumes, and if you notice an unknown device, you can block it with a single click, adding it to the blacklist. MAC-This action instantly breaks the connection to the intruder.
💡
Turn on notifications about new devices. In the hotspot settings, look for the Notify Connections option to know who is using your internet even if the phone screen is off.
There's also a whitelist feature that only allows pre-approved devices to connect, which is the maximum level of control: even if you know your password, you can't connect if you don't know it. MAC-The setting requires manually entering addresses, which is time-consuming but as safe as possible.
Remember that background app updates on connected devices can quickly “eat” your data packet. It is recommended to turn off auto updates in app stores or OS settings before connecting your laptop, so that traffic is spent only on your current tasks.
Problem Solving: Phone Can't See Network or No Internet
Despite the reliability of Android, sometimes there are situations when the access point is created, but the Internet is not working or the devices can not see the network. First of all, check whether the mobile Internet is on on the smartphone itself. Often users activate Wi-Fi, forgetting that it is the mobile data channel (4G/5G) that should be used for distribution.
If you can see the network but you can't connect, try changing the channel. In some rare cases (usually in the developer settings or through an engineering menu that isn't available to everyone), you can choose a specific channel to avoid conflicts with neighboring routers, but most often, a simple restart of the access point helps: turn off and turn on again.
⚠️ Note: If you are connected to the message, “Receive” IP-And then, "Connection Error," try to forget the network on the client device and re-enter the password. IP, which may conflict with the customer’s network.
Another common reason is energy saving: Xiaomi aggressively optimizes the background, make sure that the "Access Point" or "Modem" service has a "No Limits" limit in the battery settings, otherwise the screen will go out and the distribution will stop in a couple of minutes.
In the case of a failure, resetting network settings can be a radical but effective solution, which returns all network settings (Wi-Fi, Bluetooth, mobile network) to factory values by removing stored passwords and configurations, which often eliminates software conflicts.
Impact on battery and device heating
The access point mode is one of the most energy-intensive processes for a smartphone. The radio module is in constant data reception and transmission mode, which leads to rapid battery discharge and heating of the case. Thermal throttling (decreased processor performance due to heating) can lead to a drop in Internet speed.
To minimize the negative impact, it is recommended to keep the phone on charge during a long hand, but monitor the temperature. If the device becomes too hot, it is better to remove the case or put the smartphone on a cold surface (for example, on a metal table or next to a fan), but not on soft tissue that blocks the heat sink.
💡
Long-term exposure to hotspot mode can accelerate the degradation of lithium polymer batteries, take breaks or use external cooling.
Some Xiaomi models with powerful processors and larger batteries do this better. Flagship models usually have better cooling systems. If you plan to use the phone as a router often, look for models with larger batteries (from 5000 mAh) and support for fast charging to offset your energy consumption.
It is also worth mentioning the function. USB-If you only need to share the Internet with one device (for example, a laptop), the cable connection will be more energy efficient and stable. In this case, the phone can even charge from the computer (if the computer port is powerful) or simply spend less energy on data transfer compared to Wi-Fi.
