In today's digital world, smartphones have long ceased to be just a device for making calls and have become a fully-fledged mobile office that's always at hand. Brand devices Xiaomi, especially popular series Redmi And Note, have powerful hardware and sophisticated software, allowing them to be used not only for content consumption but also for streaming. Internet sharing, or Wi-Fi hotspots, are one of the most popular options when a stationary router is unavailable or not working properly. Mobile hotspot allows you to instantly provide a network connection to your laptop, tablet or other phone.
The process of activating the router mode on devices from a Chinese manufacturer has its own peculiarities that distinguish it from the standard one. AndroidShell interface MIUI or newer HyperOS offers advanced traffic management and security features that often remain hidden from the average user. Understanding the nuances of frequency range settings and encryption protocols will help avoid speed and compatibility issues with connected devices. In this article, we'll cover all aspects of transforming your Xiaomi to the wireless network source.
It's worth keeping in mind that phone software is regularly updated, and the location of some menu items may change slightly depending on the firmware version. The MIUI 13, 14, and HyperOS interfaces may have visual differences in icons and section names, but the operating logic remains the same across the entire ecosystem. Therefore, if you don't find an exact match for a given item, look for similar terms. The main thing is to configure security settings correctly to prevent unauthorized access to your traffic.
Quick activation via the notification shade
The easiest and fastest way to enable tethering mode doesn't require delving into the system settings. To quickly access the feature, simply unlock your smartphone and swipe down from the top of the display to open the control panel. This is where you'll find toggles for key functions, such as the flashlight, Bluetooth, and, of course, mobile hotspot. Tapping the corresponding icon instantly activates tethering mode if it's already configured.
However, simply turning it on may not work if you're doing this for the first time or have reset the network settings. In this case, long-pressing the access point icon will redirect you to the configuration menu. Here, it's important to pay attention to the network name, which by default often includes the device model, for example, Redmi Note 12. Standard name It's better to change it to something more unique so that in crowded places (cafes, offices) your clients don't confuse your phone with someone else's.
⚠️ Important: When activating a hotspot through the "curtain," make sure your mobile data is enabled. If your SIM card is blocked or there is no coverage, hotspot sharing will not work, even if Wi-Fi is enabled.
For time-conscious users, there's the option to set up automated scenarios. You can program your phone so that the hotspot turns on automatically when you connect it to a charger or at a specific time of day. This eliminates the need for manual steps each time. This approach is especially convenient for those who use their smartphone as the primary internet source for their laptop while out and about.
Deep access point settings in the menu
To fully control your internet connection, navigate to the main settings menu. The path typically looks like this: Settings → Wi-Fi HotspotThis section contains all the important settings that affect connection stability and security. This is where the initial configuration is performed, which will determine how easily and securely other devices will connect to your network. Xiaomi.
The first thing that requires attention is setting a strong password. The system may offer a random set of characters by default, but for personal use, it's better to choose a memorable combination. It's important to choose the right encryption type. Modern devices support the standard. WPA3-Personal, which provides maximum protection, but older devices may not recognize it. In this case, the optimal choice remains WPA2-Personal.
☑️ Configuring access point security
The frequency range setting deserves special attention. In the menu, you can choose between 2.4 GHz and 5 GHz. Range 2.4 GHz It has a longer range and penetrates walls better, but it is often overloaded by neighboring routers and microwaves, which reduces the speed. Range 5 GHz Provides high data transfer speeds and is less susceptible to interference, but has a shorter range. The choice depends on your needs: 5 GHz is better for watching 4K video, while 2.4 GHz is sufficient for simple messaging.
You can also configure network hiding in this section. If you enable "Hide Device," your phone will not display the network name in the general list of available connections. You will only be able to connect manually by entering the exact network name (SSID) and password. This increases your privacy, as others will not see your access point in the list of available networks.
Advanced Options: AP Band and Max Clients
Smartphone owners Xiaomi The hidden engineering settings menu of an access point, which allows for fine-tuning of radio module parameters, is often underestimated. By going into the advanced settings, you can find the "AP Band" item. This is where you can force the standard mentioned above. Forced installation 5 GHz may solve slow speed issues when there are too many competing 2.4GHz networks in the air.
Another critical setting is "Max Clients." By default, the system can allow connections for up to 10 devices. However, if you're sharing the internet with a single laptop, there's no point in keeping nine extra slots open, as this drains processor and battery power. Limiting the number of clients to one or two also improves security by preventing unauthorized access from "neighbors" if a password is leaked.
| Parameter | The meaning of 2.4 GHz | The meaning of 5 GHz | Recommendation |
|---|---|---|---|
| Speed | Up to 150-300 Mbps | Up to 400-800 Mbps | For streaming and gaming |
| Range | High (up to 30-40 m) | Medium (up to 15-20 m) | For a large area |
| Penetration | Good | Low | For rooms with walls |
| Noise immunity | Low (a lot of noise) | High | For apartment buildings |
Don't forget about the turn-off timeout. The "Turn off hotspot automatically" feature helps conserve battery life. You can set a timeout, such as 5 or 10 minutes, after which, if no one is connected to the hotspot, it will turn off automatically. This prevents you from forgetting to turn off the hotspot and letting your phone run out of battery in your bag.
Secrets of the Engineering Menu
In some versions of MIUI, there is a hidden menu that is accessible by entering a code in the dialer (for example, ##4636##), where you can see detailed Wi-Fi module usage statistics and signal strength in dBm. However, using these codes requires caution, as changing some parameters may lead to unstable operation of the radio module.
Compatibility issues and network visibility
Users often encounter a situation where a laptop or old tablet simply does not see an access point created on a modern RedmiThis is a classic issue with compatibility between security protocols and frequency bands. New phones may default to the WPA3 standard, which isn't physically supported by devices released more than 5-7 years ago. In this case, the client device simply ignores the network.
To solve this problem, you need to go back to the access point settings and forcefully change the encryption type to WPA2-PersonalThis is the most universal standard, supported by virtually every Wi-Fi module built in the last 15 years. It's also worth checking if the 5 GHz band is set if the receiving device only operates in the 2.4 GHz band (which is typical for budget laptops and older smartphones).
⚠️ Important: If you change the frequency or encryption settings, be sure to turn the access point off and on again. The changes will only take effect after restarting the sharing module.
Another reason for a network being invisible is having the "Hide Device" option enabled. If you previously enabled this feature for security but forgot to do so, the new device won't be able to find the network by scanning. You'll have to either temporarily disable hiding or manually enter the network name (SSID) in the Wi-Fi settings on the client device. Make sure the case-sensitivity setting matches the one configured on your phone.
The impact of Wi-Fi distribution on battery life and heating
Hotspot mode is one of the most power-hungry processes on a smartphone. The radio module simultaneously receives a signal from a cellular tower (4G/5G) and transmits data via Wi-Fi, creating a double workload. Xiaomi Redmi, despite their capacious batteries, can still drain after 2-4 hours of active broadcasting, especially when using the 5 GHz band and connecting multiple devices. High loads also lead to noticeable heating of the case.
To minimize the negative impact on the battery, it is recommended to use the original charger when sharing. Connecting to an external power source not only compensates for energy consumption but also prevents deep discharge, which is harmful to lithium-polymer batteries. Furthermore, when connected to the power grid, the phone can maintain a higher processor speed, which improves data throughput.
There's a myth that constantly running in router mode quickly "kills" the battery. In fact, it's overheating that's harmful. If you plan to use your phone as a permanent router, it makes sense to limit the battery charge to 60-80% (if this feature is available in the firmware or via third-party apps) and ensure proper device cooling. Under these conditions, Xiaomi can work for years without losing capacity.
Alternative connection methods: USB and Bluetooth
If wireless distribution is impossible or unstable for some reason, Xiaomi offers excellent alternatives. USB tethering mode allows you to share your internet connection via a cable. This ensures maximum speed, eliminates latency (ping), and, importantly, charges your phone simultaneously. To activate, connect the cable to your computer and select "USB tethering" in the hotspot menu. Your computer will automatically recognize the new network connection.
Bluetooth modem is an emergency option when you need to transfer minimal data (for example, a text message in a messenger) and the Wi-Fi module is damaged or busy. Speeds are extremely low, and setting up such a connection is more complicated: you need to pair the devices and select the "Internet Access" profile. However, this method consumes significantly less power than Wi-Fi, which can be crucial when the battery is critically low.
When using a USB modem on Windows computers, driver issues may arise, especially on older versions of the OS. In this case, the system may detect the phone as a storage device but not as a network card. The solution lies in selecting the USB mode in the notifications: switch from "Charging" or "File Transfer" to a network-related mode, although in modern versions Android And MIUI This often happens automatically when you turn on the toggle switch in the settings.
Why won't my phone let me turn on the hotspot?
Most often, the problem lies in power saving. Check if "Ultra Power Saving" or "Airplane" mode is enabled. The hotspot may also be blocked if data is disabled in the mobile network settings or if the data limit has already been reached. Sometimes, simply restarting the phone helps.
Is it possible to share Wi-Fi if the phone is connected to a Wi-Fi network?
On most modern smartphones Xiaomi Android 10 and above have a feature called "Wi-Fi Share." It allows you to receive and share internet over Wi-Fi. However, this feature isn't available on all models and depends on the chipset version. If this option isn't available, your phone will offer to use your mobile data for sharing.
How do I know who is connected to my hotspot?
In the access point management menu on Xiaomi A list of connected devices is usually displayed. You can see the device's name and MAC address there. If you notice an unknown device, change the password immediately and, if necessary, add the offending device's MAC address to the blacklist if your firmware version supports this feature.
Does Wi-Fi sharing affect mobile internet speed?
Yes, it does. The channel is shared between devices. If several active users are connected to the access point, the speed for each will be lower than with a direct phone connection. Furthermore, the broadcasting process itself places additional load on the radio module, which can slightly increase ping in online games.
