The modern smartphone has long ceased to be just a device for calls, becoming a universal tool for solving any tasks, including providing other gadgets with access to the global network. Xiaomi Redmi Note 9 Pro with its powerful communication module and support for current data transmission standards is ideal for creating a personal access point. Owners often face the need to connect a laptop to the Internet on a trip or give access to a tablet where there is no wired provider.
The process of activating the modem in the MIUI shell installed on the Redmi Note 9 Pro is quite convenient, but hidden settings can significantly affect the speed and stability of the connection. Many users limit themselves to standard inclusion, unaware of the possibility of selecting a frequency range or limiting traffic for connected devices. Understanding these nuances will allow you to optimize network operation and save battery power.
In this guide, we will take a look at all the steps of setting up, from basic activation to advanced security and energy saving options, how to hide your network from outsiders, what frequency range to choose for maximum speed, and what to do if the connected device does not see the access point.
Basic activation of the Wi-Fi access point through settings
The easiest and most obvious way to start a distribution of the Internet is to use the standard operating system settings menu. First, you need to unlock the Redmi Note 9 Pro screen and go to the main application menu, where you should find an icon called Settings. Inside the section, you are interested in the Wi-Fi hotspot, which is usually located at the top of the list or in the Connection and Sharing category.
After you go to the appropriate menu, you will see a switch that activates modem modem. However, before turning on, it is recommended to click on the name of your network to change the standard name of the device that defaults the phone model, which will hide personal information and easily identify your hotspot among many others in range.
The system generates a complex combination of characters automatically, but for the convenience of connecting other devices, it can be replaced with a more memorable one, while observing security requirements. The encryption protocol is set to the WPA2 PSK value by default, which is the best choice for compatibility with old and new devices.
- 📱 Click on the gear icon next to the access point switch to enter the advanced settings.
- 🔒 Set a password at least 8 characters long using letters and numbers to protect against hacking.
- 📡 Check the frequency range by choosing 2.4 GHz for compatibility or 5 GHz for speed.
- ⚙️ Activate the Wi-Fi Access Point switch to start distributing traffic.
⚠️ Note: When activating the access point, the system may warn you that 5GHz is not supported in your region, in which case you must agree to switch to the 2.4GHz standard, as this is a legal requirement.
Frequency range and security standards
Choosing the right frequency is a critical factor in determining data rate and signal range. On the Xiaomi Redmi Note 9 Pro, a range setting is available that allows you to switch between 2.4 GHz and 5 GHz. The first option provides a wider coverage radius and better penetration through walls, but suffers from the load of airborne with many neighboring networks and household appliances.
The second option, 5GHz, offers significantly higher speeds and less interference, which is ideal for streaming video or online gaming on a connected laptop. However, the range of this signal is significantly smaller and it passes through obstacles worse. If you are in a densely built apartment building, choosing 5GHz can be a salvation from low speeds.
It’s also important to look at encryption standards in your security settings. Although modern devices support WPA3, for maximum compatibility with older tablets or game consoles, it’s better to leave the WPA2 recommended system. Changing this option unnecessarily can cause some gadgets to simply stop seeing your network or refuse to connect.
There is also a hidden way to control network visibility, and by activating the SSID concealment function, you will make your access point invisible to normal scanning, and you can only connect to it manually by entering the exact network name and password, which adds an additional level of privacy in public places.

Distribution of Internet via USB and Bluetooth
Wireless connectivity is not always the best solution, especially when maximum stability is important or you need to save battery power of the receiving device. Xiaomi Redmi Note 9 Pro supports the function of the device. USB-A modem that allows Internet traffic to be transmitted to a computer via cable, which eliminates speed loss due to radio interference and simultaneously charges the smartphone.
To activate this mode, you need to connect the phone to a PC or laptop using high-quality cable USB. The access point menu will be an active item «USB-Once it is turned on, the computer will recognize the smartphone as a network device and automatically install the necessary drivers if they were not installed previously.
A Bluetooth modem is an alternative for devices that don’t support Wi-Fi or USB, such as older navigators or simple phones, and the data rate will be much lower, and the setup will require pairing devices, but it is a reliable way to access the network in an emergency.
When using a wired connection, it is important to take into account that the transmission speed will be limited by the possibilities of the transmission. USB-Computer port and cable quality. USB It can achieve speeds comparable to 5GHz Wi-Fi, but only when using original or certified accessories.
