Before you start, disable auto-update apps in Google Play and App Store on a connected laptop so as not to waste mobile traffic.
Setting up a Wi-Fi hotspot on Redmi 9
The most popular and convenient method is to create a wireless network. To begin, go to the settings menu of your device. Find the Wi-Fi Access Point section, which is usually located in the Connection and Sharing or More group, depending on the version of the MIUI operating system.
In the window that opens, you will need to specify a network name (SSID) and password. Use a strong password containing letters and numbers to prevent unauthorized people from connecting. The standard WPA2-Personal encryption protocol provides an adequate level of protection for home use.
Special attention should be paid to the frequency range setting. In the “Setting up the access point” menu, you can choose between 2.4 GHz and 5 GHz. The 5 GHz range provides higher speed, but has a shorter range and breaks walls worse, while 2.4 GHz is more versatile.
- 📶 2.4 GHz range: suitable for most devices, has a large coverage area, but can be congested by neighbouring routers.
- 🚀 5 GHz band: provides maximum data transfer speed, ideal for watching high-resolution video.
- 🔒 Hidden Network: An option to hide the network name from the list of available connections on other devices.
After entering all the parameters, be sure to put the Wi-Fi hotspot slider into the active position. The smartphone will start broadcasting the signal, and you will be able to find your network in the list of available connections on the laptop.
☑️ Checking Wi-Fi settings
⚠️ Note: When activating the Wi-Fi hotspot, the smartphone can automatically disable a previously installed Wi-Fi connection if it was used to access the Internet.
Distribution of the Internet through USB-cable
If you want maximum connection stability or want to charge your smartphone at the same time, use a wired connection. This method is also relevant if the Wi-Fi module on the laptop is defective or the drivers are not working correctly. USB-cable, preferably original or certified.
Connect Xiaomi Redmi 9 to your computer and wait for the device to be determined. In the settings menu, go to the Wi-Fi Access Point section and find the item «USB-If the item is gray, check the cable or try another one. USB-laptop-port.
Activate the switch. USB-The computer's operating system must automatically install the drivers and determine the new network connection. Unlike Wi-Fi, you don't need to enter a password here, because the connection is established over a physical channel.
The advantage of this method is the absence of radio interference and lower power consumption of the smartphone compared to wireless distribution, in addition, the cable connection is less susceptible to external factors and provides a constant speed without jumps.
What to do if the computer can’t see USB-modem?
Using Bluetooth to Transfer Data
Bluetooth modems are the least popular, but sometimes the only possible, option when other methods are not available, and the data transfer speed is much lower than over Wi-Fi or USB, so this method is only suitable for text documents or mail.
First, you need to pair your smartphone and your laptop. Turn on Bluetooth on both devices and find Redmi 9 on the list of available gadgets. Confirm the pairing code on your phone and computer screen.
Once you have successfully created a pair, go back to your smartphone hotspot settings and turn on the “Bluetooth modem.” On your computer, through the Bluetooth Device Control Panel, find your phone and select the “Connect through” option -> “Access Point.”
This method is low in power consumption, but takes longer to set up and establish a connection, and can be a lifeline in an emergency situation when there is no cable at hand and the laptop’s Wi-Fi module is out of order.
Advanced settings and optimization
The MIUI shell gives users access to a number of advanced settings that allow users to fine-tune the access point. The configuration menu can change the maximum number of connected devices. By default, there can be up to 10, but to save battery, it is better to limit the number to 2-3.
There's also a Timeout feature available, which means that if no one is connected to the network for a given time, the smartphone will automatically turn off the distribution, which will save battery power, which is especially useful if you forgot to turn off the modem after work.
For advanced users, the possibility of setting up is interesting IP-Subnet addresses and masks, although in most cases, standard values are ideal, and these parameters may need to be changed in corporate networks with strict security policies.
| Parameter | Recommended value | Impact on work |
|---|---|---|
| Frequency range | 5 GHz (if supported) | High speed, less interference |
| Max. clients. | 3-4 | Speed stability for everyone |
| timemouth | 5 minutes or 10 minutes. | Savings in battery charge |
| Encryption | WPA2-Personal | Security of data |
💡
The optimal setup for office work is the 5GHz range and limiting the number of customers to 3, which will ensure maximum speed for your devices.
Troubleshooting and troubleshooting
Despite the ease of setup, users may encounter problems connecting.Often laptops don't see the network created or can't get access to it. IP-First of all, try rebooting both your smartphone and your computer, and that solves 90 percent of software failures.
