Often there is a situation when a laptop or tablet does not have access to Wi-Fi, and the only way out is to use the mobile Internet of your device. The MIUI operating system, on which the shell of the phone is based, has powerful functionality to create an access point.
The process of activating modem modem in Redmi 9 does not require deep technical knowledge, but knowing some of the nuances will help to avoid problems with connecting other gadgets. You can transfer data in various ways, each of which has its advantages depending on the situation.
Before you start setting up, make sure that your SIM-The map activates the mobile data packet and has network coverage. Without this step, the next steps will not lead to the desired result, because the phone will not have anything to broadcast to other devices.
Setting up a Wi-Fi hotspot on Redmi 9
The most popular and convenient way to distribute traffic is to create a wireless network Wi-Fi Hotspot. This method allows you to connect multiple devices at once, including laptops, tablets and friends' phones. To get started, you need to get into the appropriate settings menu of your Xiaomi.
Open the main menu and find the Settings icon, then go to Wi-Fi Access Point. In some firmware versions, this item may be inside the Connect and Sharing menu, and that's where the main controls for your smartphone's network interface are located.

In the access point settings menu, you'll see a switch that you want to activate. Immediately after you turn on, the system will prompt you to specify the network name (SSID) and password. The password should be complex enough that neighbors or random passers-by cannot use your traffic without your knowledge.
- 📶 Security Standard: Choose from WPA2 PSK for maximum compatibility and protection.
- 📡 Frequency range: preferably 2.4 GHz for better signal range.
- 🔒 Hiding the device: the option allows you to make the network invisible to unauthorized scanners.

Use the 5GHz band only if the receiving device is very close to the phone, as this signal is worse through walls, but provides a higher data rate.
Distribution of the Internet through USB-cable
If you want maximum connection stability or need to charge your phone while you are working, a wired connection is the best choice. USB-The modem in Redmi 9 not only provides data transfer, but also battery power, which is critical for long sessions.
To activate this mode, connect your smartphone to your computer using a quality USB cable.

Using Bluetooth modem to save energy
A third option that users often ignore is Bluetooth Internet, which is a much lower power consumption than Wi-Fi, which allows the phone to run in modem mode for much longer, and the transmission speed is lower, but it's quite acceptable for simple tasks.
Before you turn on the mode, you need to pair your Redmi 9 with a receiving device (for example, a laptop). Go to the Bluetooth settings on both gadgets, find the device in the list and confirm the pairing code. Without successful pairing, you can not distribute the Internet.
Once paired on your phone, the Wi-Fi Access Point menu will open a Bluetooth modem. Turn it on, and then on your computer, in the Bluetooth device settings, find your phone and select Connect via -> Internet Access Point. The connection installation process can take up to 10-15 seconds.

|---|---|---|---|
| Speed. | Tall. | Medium/High | Low. |
| Battery consumption | High-pitched | Charging. | Low. |
| Range. | Up to 15 meters. | Cable length | Up to 10 meters. |

Connected Customer Management and Security
Controlling those connected to your network is an important part of using the Xiaomi Redmi 9 as a router. The access point menu has a list of connected devices where they are displayed. MAC-This allows you to quickly identify "uninvited guests».

Optimizing MIUI settings for stable operation
MIUI is known for aggressive power optimization, which can sometimes cause hotspot failures. To avoid a modem being turned off spontaneously, you need to make changes to your battery settings, especially if you've been using your phone as your primary Internet source for a long time.
Go to the Battery menu, click on the settings icon (usually a gear) and find Power Saving Modes. Select Performance or No Limits mode for the network connection application, although newer versions of MIUI often regulate this globally for system services.
Also worth checking is the screen settings. If the screen goes out, the phone may try to go into deep sleep mode by breaking the connection. In the Lock screen section, increase the time before going into sleep mode or use the "Do not turn off the screen when charging" function if you are working via USB.

If your computer sees the network but writes "No Internet access," check if the mobile Internet is on in the notification curtain. Sometimes the MIUI priority system may turn off data transmission if the network signal is weak or switches between 3G and 4G.

Rebooting network settings solves problems with the invisibility of the access point or the lack of Internet on connected clients in 90% of cases.
