Modern Xiaomi Redmi smartphones have become powerful multimedia centers, capable of performing tasks previously reserved for desktop devices. One of the most sought-after features is the ability to transform the gadget into a full-fledged mobile routerThis is especially relevant when you urgently need to connect a laptop or tablet to the network, but traditional Wi-Fi is unavailable or unstable. Users often look for ways to quickly enable this feature without delving into complex system settings.
In the operating system MIUIThe Wi-Fi hotspot app installed on Redmi devices offers a flexible process for setting up a wireless network. The interface not only allows you to enable data transfer but also fine-tune security settings, frequency range, and the list of connected clients. Understanding these settings will help you avoid speed issues or unexpected data consumption. In this article, we'll cover all the nuances of creating an access point.
Sometimes standard activation methods may fail due to software glitches or carrier restrictions. In such cases, a more in-depth diagnosis and alternative setup methods are required. We'll cover common errors and effective troubleshooting methods to ensure you always stay online.
Basic hotspot setup via the notification shade
The fastest way to activate tethering is to use the quick access panel. Simply swipe down from the top of the screen to open the notification shade. Among the many icons, find the one labeled Access point or HotspotClicking this button instantly starts the internet sharing process.
However, if you're using this method for the first time, the system may ask for confirmation or offer basic settings. In some versions of the shell MIUI Long-pressing the icon takes you directly to the configuration menu. This allows you to set the network name and password before other devices attempt to connect. Ignoring this step may leave your network open to outsiders.
⚠️ Attention: When activating the hotspot via the curtain, make sure your mobile data connection is enabled. If data is disabled, Wi-Fi hotspot access won't work, even if the indicator light is on.
For increased security, it's recommended to set a strong password from the start. Simple combinations like "12345678" are easily guessed by third-party programs, which could lead to theft of your traffic. It's best to use a combination of letters and numbers at least eight characters long. This will take a couple of seconds, but will protect your network from intruders.
Advanced configuration in the MIUI settings menu
For those who want full control over their network settings, there's a system settings menu. To access it, go to the section Settings → Wi-Fi HotspotThis section provides access to advanced options not visible in the quick menu. This section is where you configure the Wi-Fi standard and manage connected devices.
One of the key features is frequency band selection. Modern Xiaomi Redmi smartphones support both the 2.4 GHz and 5 GHz bands. Band selection 5 GHz Provides higher data transfer rates, but has a shorter range and is less able to penetrate walls. The 2.4 GHz band is more versatile and compatible with older devices.
In this same menu, you can set up automatic hotspot shutdown. This feature is useful for saving battery power: if no one connects to the network for a set period of time (for example, 10 minutes), the phone will automatically turn off tethering mode. Also available here QR code, which, when scanned, allows another device to connect without manually entering a password.
- 📡 Network Name (SSID): Allows you to set a unique name by which other gadgets will search for your device.
- 🔒 Safety: Select the encryption protocol, it is recommended to leave WPA2 PSK for maximum compatibility.
- 👥 Connected devices: View a list of gadgets using your internet right now.
- ⏱️ Timer: Setting the access point operating time before automatic shutdown.
☑️ Check security settings
Don't forget about the whitelist feature. You can limit the number of devices that can be connected or completely block new devices from connecting until you add them to the whitelist. This is especially useful in public places where strangers might try to connect to your network. Access control is available through the "Connected Devices" menu in the same settings.
Using a USB modem for a stable connection
When the wireless connection is unstable or maximum speed is required, it is advisable to use a wired connection via a USB cable. This method, known as USB modem, allows you to stream internet from your phone to your computer while simultaneously charging your smartphone. To activate, connect the device to your PC with a cable and go to the hotspot settings menu.
Unlike Wi-Fi, there's no need to enter passwords or search for a network. After connecting the cable, go to the menu Settings → Wi-Fi Hotspot → USB Tethering Simply move the slider to the active position. The computer will automatically recognize the new network connection. This method is ideal for desktop workstations where ping stability is important.
⚠️ Attention: When using a USB modem, make sure the drivers for your smartphone are installed on your computer. In most cases, Windows 10 and 11 install them automatically, but older versions of the OS may require manual installation of ADB or Mi PC Suite drivers.
The advantage of a wired connection is the absence of radio interference and lower power consumption compared to an active Wi-Fi module. The phone runs cooler, and the data transfer speed is limited only by the bandwidth of the cable and USB port. However, it's important to note that sharing Wi-Fi and USB data to different devices simultaneously is usually not possible—one active mode is selected.
Why doesn't the computer see the USB modem?
If your computer isn't responding to the connection, check your cable. Cheap cables are often designed only for charging and don't transfer data. Try replacing the cable with the original or a high-quality one that supports data transfer. Also, check if USB debugging is enabled in the developer options, although this is usually not required for a basic modem.
Operator restrictions and bypassing blocking
Many users encounter a situation where the hotspot turns on, but the internet on connected devices doesn't work. This is often due to mobile operator tariff plans. Some providers prohibit or limit internet sharing to other devices, requiring a separate fee or an activated option. This is technically implemented through parameter analysis. TTL (Time To Live).
Each data packet has a TTL value. When you share internet, this value changes, and the operator sees that the traffic is going to a third-party device rather than your phone. In response, the network may block the connection or charge a separate, more expensive rate. To avoid this, users change the TTL value in their phone settings.
Changing TTL requires access to the engineering menu or the use of special applications that require root rightsWithout superuser rights, it's impossible to change system network settings at the Android kernel level. This feature can't be changed using standard MIUI tools. This is an important point to be aware of before attempting to bypass restrictions.
| Parameter | Standard value | Recommended value | Influence |
|---|---|---|---|
| TTL (Linux/Android) | 64 | 65 | Disguising the distribution |
| TTL (Windows) | 128 | 129 (on PC) | Match with phone |
| Protocol | IPv4/IPv6 | IPv4 | Stability |
| APN type | default,supl | default,supl,dun | Modem resolution |
There's also a method for changing the APN type. In the mobile network settings, find your carrier's access point, create a new one, or edit an existing one. Adding a parameter to the "APN Type" field can sometimes help. dun (dial-up networking). However, modern operators have learned to recognize this method, so it doesn't always work. Its effectiveness depends on the specific SIM card and region.
Troubleshooting connection and speed issues
If the hotspot is enabled, but devices don't see the network or can't connect, the issue may be with security settings or the frequency range. Some older laptops or tablets simply don't support the 5 GHz standard. In this case, you'll need to force the phone to switch to wireless mode. 2.4 GHz via the access point settings menu.
Another common cause of crashes is a full network settings cache or an IP address conflict. In this case, resetting the network settings helps. Go to Settings → Connection and sharing → Reset Wi-Fi, mobile networks, and BluetoothPlease note that this action will delete saved passwords for all Wi-Fi networks, so you will have to enter them again.
Smartphone overheating is a common cause of slower speeds or spontaneous disconnection of data sharing. When actively transferring data, the processor and radio module operate at their limits. If your phone becomes hot, remove the case and place it on a hard surface to improve heat dissipation. Prolonged overheating can lead to throttling (decreased performance) and rapid battery drain.
- 🔋 Energy saving: Power saving modes can block background hotspot operation by turning it off when the screen is off.
- 🛡️ Antivirus: Third-party security applications sometimes block incoming connections, considering them suspicious.
- 📶 Signal: A weak cellular network reception level (1-2 bars) will not allow for stable distribution speed.
- 🔄 Reboot: A simple phone restart solves 90% of network software glitches.
The impact of Wi-Fi sharing on the battery and device
Hotspot mode is one of the most power-hungry processes in a smartphone. The radio module simultaneously receives a signal from the tower and broadcasts it over Wi-Fi. This leads to accelerated battery drain and increased heat generation. Owners of older Redmi models with worn-out batteries should be especially careful.
When using the modem mode for long periods, the case temperature can reach 40-45 degrees Celsius or higher. This is normal for heavy use, but requires monitoring. If the phone is too hot, the MIUI system may automatically limit the charging speed or stop charging altogether until it cools down to prevent damage to the batteries. Therefore, it's best to keep the phone near a fan or on a cool surface during long periods of use.
⚠️ Attention: Don't cover your phone with a cloth or pillow while using Wi-Fi. Lack of ventilation can cause the battery to overheat and swell. Use only hard surfaces.
To minimize damage, it's recommended to use the original cables and power adapters when using mains power. Fast charging will help offset the high power consumption. You can also use the "Charging Optimization" feature in the battery settings, although it may be less efficient in active sharing mode. Monitor the battery status in the menu. Settings → Battery.
