Every smartphone owner faces situations where they urgently need to provide a second device with access to the global network. Device owners Xiaomi And Redmi People often wonder how to activate tethering mode to share data with a friend's tablet or gadget. The standard shell interface MIUI or new HyperOS has its own peculiarities that can confuse an inexperienced user.
Unlike simply enabling Bluetooth, creating a full-fledged access point requires understanding several nuances of how the radio module works. Wi-Fi hotspot Turns your smartphone into a miniature router that broadcasts a signal over a certain distance. It's important to keep in mind that this consumes your mobile carrier's data and significantly increases energy consumption.
In this guide, we'll cover the steps for the latest firmware versions in detail. We'll cover security, frequency band selection, and troubleshooting common connection issues. Proper setup will allow you to use your smartphone as a reliable internet source anywhere within cellular coverage.
Preparing your Redmi smartphone for router mode
Before activating the distribution mode, you must ensure that the device is ready to perform these functions. Mobile Internet The SIM card must be active and have a stable signal, otherwise connected clients won't be able to load even simple pages. Also, check your SIM card balance and make sure your data plan allows data sharing, as some carriers block or limit this feature.
Battery charge plays a critical role. Broadcasting a wireless signal places a high load on the processor and radio module, leading to rapid battery drain. If the battery level is below 20%, it is recommended to connect the device to a power source before starting a sharing session.
☑️ Check before launching the access point
It's also worth deciding in advance how many devices you plan to connect. Although the system Android at the base MIUI Allows you to connect up to 10 clients, but actual speed will decrease with each additional device. For comfortable operation, it's best to limit yourself to 2-3 devices simultaneously.
Step-by-step Wi-Fi hotspot activation
The process of enabling modem mode in smartphones Redmi The settings are standardized, but the path to the settings may vary slightly depending on the shell version. Most often, users use the quick actions panel, but for initial configuration, it's better to access the full menu.
Go to the main settings of the device and find the section Connection and sharing (or simply "Access Point" in older versions). This is where the switch is located. Wi-Fi hotspotOnce activated, your phone will begin broadcasting a signal. By default, the network name usually contains your phone model, for example, Redmi Note 10.
⚠️ Caution: Immediately after turning on the hotspot without changing the password, other devices may connect to your network if they are nearby and have previously accessed it. Always set a strong password before first use.
You can use the notification shade for quick activation. Swipe down from the top to open the control center and find the "Tethering" icon. Long-pressing this icon usually takes you directly to the settings menu, saving you time.
Setting up security and network name
The security of your personal network is our number one priority. You can change the default settings in the access point settings menu, which you can open by clicking on the name or through the "Access point settings" menu. Network name (SSID) It is better to make it unique so as not to get confused with neighboring routers in an apartment building.
In the password field, use a combination of letters and numbers of at least 8 characters. The system suggests a default encryption type WPA2 PSK, which is the optimal choice for compatibility with both old and new devices. The newer standard WPA3 may be unavailable or cause connection issues on older devices.
| Parameter | Recommended value | Impact on work |
|---|---|---|
| SSID (Name) | Unique (in Latin) | Makes network searching easier |
| Password | Minimum 10 characters | Protects against hacking |
| Range | 2.4 GHz (compatibility) / 5 GHz (speed) | Determines range and speed |
| Device limit | 3-5 pieces | Maintains internet speed |
The "Hide Network" feature is often hidden in this menu. If enabled, your phone won't be visible when scanning for available networks. Connecting requires manually entering the network name on the receiving device, which increases privacy.
Choosing a Frequency Band: 2.4 GHz vs. 5 GHz
One of the key settings in modern smartphones Xiaomi The choice of broadcast frequency is crucial. The 2.4 GHz band is often selected by default, as it has better wall penetration and is compatible with the vast majority of devices.
However, if you need the maximum data transfer speed and you are in close proximity to the receiving device, it makes sense to switch to 5 GHzThis range is less congested with neighboring routers and provides a more stable ping, which is critical for online gaming or video calls.
What is the difference between frequencies?
The 2.4 GHz band penetrates walls better, but has lower speeds and is heavily contaminated with noise. The 5 GHz band offers high speeds, but the signal quickly fades as you move away from the phone or encounter obstacles.
To change this setting, go to Setting up an access point -> Access point frequency rangeHere, select the desired option. Keep in mind that if you select 5 GHz, older laptops or tablets may simply not see your network.
Limiting connected devices and traffic
The connection limiting feature is extremely useful when you're in a public place. You can strictly limit the number of clients that can simultaneously use your internet. This setting is typically found under "Device Management" or "Connected Devices" in the hotspot menu.
This displays a list of all devices currently using your Wi-Fi. You can see their MAC addresses and the amount of data transferred. If an unknown user appears on the list, you can block them with one tap, which will immediately disconnect you from them.
Also in MIUI There's a traffic limiting feature. You can set a limit of, for example, 1 GB. Once all connected devices have used up this amount, internet tethering will automatically be disabled. This prevents you from unexpectedly falling into the red when billing per megabyte.
⚠️ Please note: Telecom operator interfaces and plan terms change frequently. Before actively distributing large amounts of data, check your plan terms in your operator account to avoid service blocking.
Troubleshooting connection and visibility issues
Sometimes it happens that the sending phone is broadcasting the network, but the second phone can't see it or can't connect. First, check that the receiving device isn't in "Data Saver" or "Smart Wi-Fi" mode, which can block the connection to mobile hotspots.
If the problem persists, try resetting the network settings. To do this, find the reset button in the access point menu, or simply change the network name and password and save the new settings. This will force the radio to restart in server mode.
Another common cause is incompatibility of security protocols. If the old laptop can't see the network created by the new one Redmi, try changing the protocol version in the access point settings WPA3 on WPA2 or even WPA/WPA2 Mixed.
The impact of Wi-Fi distribution on battery and heating
The physical aspect of a smartphone operating in router mode cannot be ignored. Active data transfer via Wi-Fi module This causes significant heating of the device, especially around the camera and the top of the device. In summer or in direct sunlight, this can lead to throttling (reduced performance) or temporary shutdown of the overheating function.
Battery drain in this mode can reach 15-20% per hour, even without active use of the phone itself. Therefore, if you plan on a long session, keep the device charged or use an external battery (Power Bank).
To minimize heat buildup, remove any protective case made of thick material and place the phone on a hard surface for better heat transfer. Avoid covering the smartphone with a cloth or blanket while it's in modem mode.
Why does my phone battery drain quickly when the hotspot is turned on?
The radio module operates in constant high-power transmission mode. The processor is also active, as it must process network packets for all connected devices. This places a double load on the power system.
Is it possible to share Wi-Fi if the SIM card on the phone has a password?
Yes, you can. The PIN is only required when the phone is turned on. Once the SIM card is unlocked and the network is found, tethering works normally, regardless of whether the PIN is on the SIM card itself.
What is the maximum number of devices that can be connected to Redmi?
Technically firmware MIUI Allows you to connect up to 10 devices. However, with more than 4-5 clients, the internet speed on each device will become critically low, and the phone will start to overheat.
