Modern smartphones like the Xiaomi Redmi 9 often act as universal communication centers, replacing not only the phone, but also the router. The situation when you need to urgently connect a laptop to the Internet or share traffic with a friend’s tablet, occurs quite often, especially when traveling or when there are interruptions with wired connection. The Internet distribution function in the shell of MIUI is implemented quite flexibly, allowing not only to turn on the access point, but also fine-tuned security settings.
In this article, we will take a closer look at the nuances of creating a wireless network on your device, where advanced settings hide, how to protect the network from uninvited guests, and what restrictions the Android operating system imposes, and understanding these processes will help you avoid battery loss and protect personal data.
The process of activating modem modem does not require complex technical knowledge, but knowing some hidden features can significantly improve the stability of the connection. We will consider both standard on-line methods and specific settings available to owners of Xiaomi devices.
Basic activation of the access point through the curtain
The fastest way to start giving away the Internet is to use the Quick Action Bar, which is a standard method that works on any Android device with a MIUI shell, and you don't have to go through a lot of system settings if you just want to turn on the network for quick access.
You swipe down from top to bottom to open the notification curtain. In the icon menu that appears, find an item called Access Point or a radar-like icon. If you don't see it on the first page, swipe left or click the panel edit button.
Clicking on the icon instantly activates the handout mode, but this method does not allow you to immediately change the password or network name if you are doing this for the first time.
⚠️ Note: When you turn on the access point through the curtain, the last saved profile is used. If you previously changed the password, the new user who connected will have to enter it, not the standard code.
The convenience of quick access is the ability to instantly turn off the distribution, which saves battery power, and is especially useful when you need to transfer a file for a short time or open a page on another device.
Full configuration of network parameters in the smartphone menu
For deep configuration, you need to go to the main settings menu, which is all the key parameters that affect the stability and security of your connection, and the path to these is standard for Xiaomi Redmi 9 devices.
Go to Settings → Wi-Fi Access Point. In this section, you will see the current status, network name (SSID) and number of connected devices, and this is where the basic security settings are set up.
☑️ Checking the settings of the access point
Click on "Setting up the hotspot" and you can change the SSID to any name you like, and it's recommended that you don't use the standard phone model name to avoid attracting hackers in public.
Pay special attention to the password field. The system will require you to enter a combination of at least 8 characters. Use a mixture of letters and numbers for maximum protection. The encryption protocol is better left with WPA2-Personal, as it provides the best balance between compatibility and security.
Use of advanced settings and hide the network
The MIUI shell offers features that go beyond standard Android. One of the most useful options for advanced users is the ability to hide their network, in which case it will not appear in the list of available connections on other devices.
To activate this feature, find the Hide Device Switch in the access point menu, and once you turn on this option, you will need to manually enter not only your password, but also your exact network name (SSID), which creates an additional layer of protection against random connections.
⚠️ Note: Hiding the network is not a method of encryption. experienced users with the appropriate software will still be able to detect the presence of hidden information. SSID, But for the average user in a cafe, this is an effective measure.
Also in the advanced settings, you can find the "Access Point Timer" feature, which allows you to automatically turn off the Internet distribution if no one is connected to it for a specified time (for example, 5 or 10 minutes), which significantly saves battery power.
Why are they hiding the network?
Another important option is to limit the number of connections you have, so you can set a limit to, say, 3 devices, and this will prevent your phone from getting choked up by a lot of requests, which is especially true for the MediaTek Helio G80 processor installed in Redmi 9.
Distribution of Internet via USB and Bluetooth
Wireless is not always the best solution, and in some cases, maximum stability or minimum signal delay (ping) is required. USB-cable.
To activate, connect your smartphone to your computer with a cable. Then go to Settings → Wi-Fi hotspot → USB-The switch will only become active if there is a physical connection, and the computer will recognize the phone as a network card.
The advantage of the method is that it doesn't interfere with radio interference and charges the device at the same time. However, the speed will be limited by the bandwidth of USB 2.0 and the quality of the cable. For older laptops without a Wi-Fi module, this is often the only Internet access.
| Parameter | Wi-Fi Access Point | USB modem | Bluetooth Tetering |
|---|---|---|---|
| Transmission speed | High (up to 150 Mbps) | Medium/High | Low (up to 2 Mbps) |
| Battery consumption | High-pitched | Charging from a PC | Low. |
| Number of devices | 10. | 1 | 1 |
| Stability | Depends on the interference. | Maximum | Medium |
Bluetooth tetering is rarely used because of its slow speed, but it can save you in an emergency situation where you need to transfer a small text file or message, and the battery is running out.
Traffic control and connection restriction
It is vital for traffic-restricted tariff owners to monitor data consumption, and MIUI has a built-in monitoring mechanism that allows you to track how many megabytes have been distributed through the access point.
The access point menu often has usage statistics, you can see which device has eaten up traffic, and if you notice abnormal activity, such as someone starting to download heavy files, you better change your password immediately.
You can use embedded scripts or third-party applications to automate the process, but you can also use standard tools to set a limit, and when it's exhausted, the distribution will automatically stop, and this will protect you from unexpected billing from the carrier.
Also worth remembering is the frequency range. In settings, you can choose between 2.4 GHz and 5 GHz. The 5 GHz range provides speed, but has a shorter range and penetrates walls worse. For Redmi 9, which supports both ranges, the choice depends on the receiving device.
Solutions and optimization of work
Sometimes users are faced with a situation where devices see the network but cannot connect, or the Internet on the connected device does not work. IP-addresses or settings DNS.
Try restarting the hotspot or the smartphone itself. If the problem persists, check if the phone is not limiting mobile traffic for background apps. Also make sure you have a stable cellular signal (3G/4G/LTE).
💡
If the internet on the connected device is slow, try manually setting the Wi-Fi channel (e.g. 1, 6, or 11) in the access point settings to avoid intersection with neighbouring routers.
Another common cause of failure is energy saving. The system can aggressively strangle background dispensing processes to save charge. In the battery settings, find the Access Point app or system dispensing process and select No Limits mode.
⚠️ Warning: Long-lasting access point causes strong heat on the smartphone body.Do not cover the Redmi 9 during the handout and remove the thick case if you feel that the device has become hot.
The influence of modem modem mode on the autonomy of the device
Wi-Fi is one of the most energy-intensive processes in a smartphone. The radio module is at its limit, constantly broadcasting the signal. For the Redmi 9 with a 5020 mAh battery, this is a tangible but acceptable load.
However, it should be noted that when used actively (for example, if you are talking on the phone or playing at the same time), the discharge will occur many times faster, on average, an active access point “eats” about 15-20% of the charge per hour.
💡
For long-term operation in router mode, it is recommended to keep the phone connected to the charger, but monitor the heating temperature so as not to damage the battery.
If you need to give away the Internet for a long period, for example, while traveling on the train, it makes sense to turn off unnecessary functions: reduce the brightness of the screen, turn off Bluetooth and GPS, close the background applications, this will prolong battery life.
Using a dark theme interface also slightly reduces power consumption, as the IPS-The Redmi 9 screen does not have the same effect as the screen. AMOLED, but reduces the overall load on the processor when rendering the interface, if the screen still lights up.
