Modern smartphones, and in particular devices of the brand Redmi, have long ceased to be just a means of making calls, having transformed into powerful multimedia centers and work tools. One of the most sought-after features in a user's arsenal is the ability to turn a gadget into a portable router distributing internet wirelessly. This option, known as modem mode or access point, allows you to instantly connect your laptop, tablet, or other phone to the global network without having to look for a free portable router or pay for additional provider services.
Owners of the devices Xiaomi And Redmi, working on the shell MIUI or new HyperOS, often encounter interface nuances that distinguish their devices from the clean AndroidStandard activation methods may be hidden deep in menus or have specific names. Furthermore, there are important technical aspects, such as frequency band selection, which directly impacts connection speed and compatibility with older devices receiving the signal.
In this article, we'll detail the process of creating your own Wi-Fi network on a Redmi smartphone, explore fine-grained security settings to prevent unauthorized access to your data, and discuss how to extend battery life when actively using this feature. Understanding these processes will allow you to confidently manage your connection in any situation, whether you're on a business trip, traveling, or simply don't have wired internet at home.
Basic hotspot settings on Redmi
The process of activating modem mode in the operating system MIUI And HyperOS The system is standardized, but the layout of elements may vary slightly depending on the firmware version. First, you need to access the main system settings menu, where all device management options are located. The settings icon is typically a gear icon located on the home screen or in the notification shade.
Once you've entered the menu, you should find the section responsible for wireless connections. In most cases, it's called "Connect and Sharing" or simply "Access Point." This is where the switch that activates router modeClicking on it will launch basic internet sharing with factory settings, which, however, are recommended to be changed for security reasons.
It's important to note that when you first turn it on, the system may ask for confirmation or prompt you to configure network settings. Don't skip this step, as the default password is often too simple or, conversely, too difficult to remember if you plan to connect devices frequently. The network name (SSID) is also displayed here, which is how other devices will see your phone in the list of available connections.
⚠️ Note: When you enable the hotspot, the system will automatically disable the Wi-Fi receiver if it was active, as the smartphone's antenna switches to transmit mode. Mobile data must be enabled for this feature to work.
There's also a faster way to activate it via the control panel. Swipe down from the top of the screen to open a shortcut menu with toggle buttons. Look for the "Access Point" or "Hotspot" icon. If it's not on the first page, swipe left or tap the edit button to add it to the shortcut menu. This allows you to create a network with one tap, which is especially handy in emergency situations.
However, the quick method doesn't provide access to advanced settings, such as changing the password or selecting a frequency band. Therefore, for initial network configuration, we strongly recommend using the full settings menu described above. This only takes a couple of minutes, but will ensure the stability and security of your connection in the future.
Setting up a network name and security password
The security of data transmitted through your hotspot is our number one priority. By default, the system generates a random network name and a strong password, but for your convenience, it's best to change these settings. The network name (SSID) is the identifier that other users see when searching for Wi-Fi. It's recommended to give it a descriptive name, such as "Redmi_User" or "My_Office_Mobile," to easily find your phone among dozens of other signals.
Password protection is a barrier that prevents strangers from connecting to your internet and consuming your data. In the access point settings on Redmi encryption protocol is used WPA2-Personal or more modern WPA3, which ensures a high level of data security. Create a password of at least 8 characters, using a combination of letters and numbers.
To change the settings, go to the access point settings menu. There you will see the "SSID" and "Password" fields. After entering the new values, be sure to click the "Save" button or the check mark in the upper right corner of the screen. This may disconnect current connections, and devices will need to re-enter the new password for authorization.
☑️ Network security check
There's also the option to make the network hidden. This will prevent your phone's name from appearing in the general list of available networks on other devices. To connect, you'll need to manually enter the network name (SSID) and password. This increases privacy, as passersby won't see your hotspot, but it does make connecting new, trusted devices a bit more difficult.
⚠️ Note: The Settings menu interface may differ depending on your MIUI version (12, 13, 14) or HyperOS. If you don't find the "Password" option immediately, look for the "Security" or "Access Point Settings" subsection within the Wi-Fi menu.
Choosing a Frequency Band: 2.4 GHz vs. 5 GHz
One of the key features of modern smartphones Xiaomi And Redmi Dual-band Wi-Fi support is a key feature. This means your phone can access the internet on both the 2.4 GHz and 5 GHz frequencies. Choosing the right band is critical to ensuring a stable connection and high data transfer speeds, especially if you plan to watch high-definition videos or play online games on the connected device.
The 2.4 GHz band is more universal and compatible. It's supported by virtually all devices, even older laptops and tablets manufactured 5-7 years ago. However, this band is often overloaded with signals from neighboring routers, microwave ovens, and Bluetooth devices, which can lead to slower speeds and unstable ping. It has a wider range and better signal penetration through walls.
The 5 GHz band offers significantly higher data transfer rates and is less susceptible to interference. It is the ideal choice for modern devices that support 802.11ac And 802.11axHowever, this signal has a shorter range and is less able to penetrate physical obstacles. If you live in an apartment with thick walls or in an area with a lot of other networks, switching to 5 GHz can provide a significant performance boost.
How to check if a laptop supports 5GHz?
To check if your device can see the 5 GHz network, open the list of available Wi-Fi networks. If you see two networks with the same name (for example, Redmi_Name and Redmi_Name_5G), your phone is broadcasting on both bands. If your laptop can only see one, check the specifications of its Wi-Fi module. Older cards may only work on 2.4 GHz.
Switching between bands on Redmi is done in the access point settings menu. There you'll find the option "Select Frequency Band" or "AP Band." By selecting "5 GHz Preferred," the phone will attempt to connect to the network in high-speed mode. If the connected device doesn't support this frequency, it simply won't see the network or won't be able to connect, so it's important to know the specifications of the client device.
Limiting connections and managing traffic
Mobile internet tethering is a resource-intensive process that consumes not only battery power but also your data plan limits. To avoid unpleasant surprises like running out of data or overheating your smartphone, the system MIUI Provides tools for tight connection control. You can manually set a limit on the number of devices that can be connected to your network simultaneously.
By default, this limit is often set to 10 devices, which can be excessive for a mobile phone. Reducing this limit to 3-5 devices will help relieve the load on the smartphone's processor and reduce heat. Furthermore, in the "Connected Devices" menu, you can always see a list of devices currently using your internet connection and, if necessary, block a specific device without even changing the master password.
It's also worth paying attention to the data saving settings. Some firmware versions offer a "Data Limit" feature that automatically disables the hotspot when the transferred data volume reaches a specified limit. This is a useful option if you have a limited data plan and want to ensure you don't go too far into the red.
| Parameter | Recommended value | Impact on work |
|---|---|---|
| Max connections | 3-5 devices | Reduces battery and processor load |
| Frequency range | 5 GHz (if possible) | Increases speed, reduces interference |
| Shutdown timeout | 10 minutes | Saves battery when there are no active clients |
| Encryption | WPA2/WPA3 | Guarantees password and data protection |
Connected devices are managed through the same menu where you set the password. By clicking on a specific device in the list, you'll see the "Block" option. This will immediately disconnect the device. If you notice a device you don't recognize, we recommend changing the hotspot password immediately, as this means someone has cracked your password.
Connection problems and their solutions
Despite the well-functioning system AndroidRedmi users sometimes encounter situations where the hotspot is enabled, but other devices can't connect or don't see the network. One common cause is an IP address conflict or a temporary outage in the operating system's network services. In such cases, a simple smartphone reboot, which resets all network configurations, often resolves the issue.
Another common issue lies in your mobile network settings. Make sure data is enabled in your cellular settings and, importantly, background internet use for system services is not restricted. Sometimes carriers block tethering on certain plans. In this case, even if you're connected successfully, pages won't load in your browser.
If your devices see the network but fail to connect, returning the "Unable to connect" error, try changing the security type. Switching from WPA3 to WPA2/WPA3 Mixed or pure WPA2 often resolves compatibility issues with older Wi-Fi drivers on laptops. It's also worth checking if your phone is in "Invisible" or "Hidden Network" mode if you're trying to find it manually.
⚠️ Note: Some mobile operators determine internet tethering by the TTL (Time To Live) value. If the internet on a connected device isn't working, even though everything loads fine on the phone, your operator may be blocking tethering. A workaround requires more complex manipulations, such as changing the TTL in the engineering menu or via root access, which is beyond the scope of the standard instructions.
It's also worth checking energy saving. Aggressive algorithms MIUI To conserve battery, phones can automatically disable the hotspot if the smartphone's screen goes dark. In the battery settings, find the "No restrictions" option for the hotspot service or disable power saving for Wi-Fi-related system processes. This will ensure stable network operation even when the phone is in your pocket with the screen off.
The impact of Wi-Fi distribution on battery and heating
Using a smartphone as a router is one of the most energy-intensive scenarios. The Wi-Fi module, transmitting data, consumes significant current, and simultaneously using the 4G/5G module to receive internet creates an additional load. As a result, the phone can become noticeably warm, especially in the summer or when using a thick case that impairs heat dissipation.
Prolonged overheating is harmful to lithium-polymer batteries: it accelerates the degradation of the battery chemistry, leading to a faster loss of capacity in the future. If you plan to use the hotspot for extended periods (for example, several hours of work on a laptop in a cafe), it is recommended to remove the protective case to improve ventilation. Ideally, place the phone on a cool surface.
To minimize damage, you can use the "Game Boost" feature or special performance profiles that optimize network performance, although these are often focused on reducing latency rather than saving power. A more effective method is to connect your smartphone to an external power source (power bank) or directly to a wall outlet, if available. However, charging your phone while actively using Wi-Fi or when it's very hot isn't always beneficial.
There's a myth that turning on airplane mode and then switching to Wi-Fi only allows you to share your internet connection. This is incorrect: to share your internet connection, your phone needs a data source, i.e., a mobile network. Therefore, it's impossible to completely disable the cellular module. However, you can disable data transfer on SIM cards that aren't used for internet, leaving only the primary slot active, which will slightly reduce the load on network search algorithms.
Why does my phone battery drain quickly when the hotspot is turned on?
Access point mode is a mode of constant, active transmission of a high-power radio signal. Unlike normal use, when the phone spends most of its time "listening" to the network and only wakes up to receive data, in router mode it constantly broadcasts a signal. Combined with 4G/5G modem operation, this creates a peak load on the battery, comparable to running heavy 3D games.
Is it possible to share Wi-Fi if there is no SIM card on the phone?
A phone without a SIM card and Wi-Fi connection cannot serve as an internet source, as it has nowhere to get data from. However, if the phone is connected to a Wi-Fi network (acting as a client), some Redmi models can create a "Wi-Fi repeater"—broadcasting the received signal further. However, traditional mobile data tethering requires an active SIM card with a data plan.
How can I find out how much traffic has been used through a hotspot?
The default MIUI/HyperOS settings may not explicitly display detailed statistics for hotspot traffic. However, the overall usage can often be seen in the "Data Usage" section (in SIM card settings). For detailed monitoring, it's better to use carrier-provided widgets or third-party traffic counter apps with the appropriate system permissions.
Does Wi-Fi sharing affect the speed of mobile internet on the phone itself?
Yes, it does. Since the radio channel is split between receiving data for the phone itself and broadcasting it to clients, overall throughput can decrease. Furthermore, the processor is busy encrypting and routing packets. If the channel is weak (for example, a weak 3G/4G signal), the speed on the connected laptop and the phone itself will be noticeably lower than when using either device separately.
