Xiaomi's smartphone today is almost impossible to imagine without constant access to the global network, because it is the Internet that turns the device into a powerful multimedia center. Without connectivity, you lose the ability to install applications, synchronize contacts, navigate in real time and even make calls through instant messengers. The process of activating communication may seem trivial, but in the MIUI ecosystem there are some nuances that are important to consider for stable operation.
In this article, we will take a look at all the ways you connect your gadget to the network, from simple steps to complex hotspot settings. You will learn how to properly configure mobile Internet if it does not work automatically, and how to optimize Wi-Fi settings for maximum speed. Understanding these processes will allow you to avoid common mistakes and save battery power.
We're going to look at situations where standard methods don't work, and we're going to offer proven solutions for different models, whether it's a budget Redmi or a flagship Xiaomi. Proper network settings are the foundation for comfortable use of all the features of the Android operating system. Let's start setting up so that your phone stays online at all times.
Connection to Wi-Fi wireless network
The most common way for Xiaomi smartphone owners to log in is to use wireless access points. First, unlock the device screen and find the Settings icon, which usually looks like a gear. In the menu that opens, select the Wi-Fi section, where the system will prompt the corresponding module to be turned on if it was previously deactivated.
Once the module is activated, the phone will automatically search for available networks within range. The network list is updated dynamically, and you need to select your router name from the list offered. If the network is password protected, the system will require you to enter the security key, which is usually indicated on the sticker under the router or in the contract with the provider.
⚠️ Warning: When connecting to public networks in cafes or shopping centers, avoid entering bank card data, as such connections are often not protected by encryption.
In some cases, you may need to manually add a network if it is hidden or not displayed in the list. To do this, select the option to Add Network and enter the exact name (SSID) and encryption type from the Wi-Fi menu. The right type of security, such as WPA2/WPA3, is critical for a successful connection.
Setting up mobile Internet via SIM-card
When you're out of range of your home router, the carrier's mobile network comes into play. To run mobile internet on Xiaomi, you need to make sure that you have the right mobile network. SIM-The card is installed correctly and your carrier's data service is activated. MIUI It allows you to flexibly manage two SIM cards at the same time.
To activate the data transfer, lower the swipe notification curtain from top to bottom and find the Mobile Internet icon (usually two up-and-down arrows). Click on it to light up, after which a 4G, LTE or 5G marking should appear next to the signal indicator. If the icon does not appear, you may need to manually configure the APN access point.
- 📱 Go to Settings and select a paragraph SIM-maps and mobile networks.
- 🌐 Click on your operator name or access point (APN).
- ⚙️ Select a New Access Point or reset existing pre-factory settings.
- 💾 Save the parameters obtained from the operator or found on its official website.
A common problem is that you don't automatically set the card when you first install it, and you don't have to panic because Android allows you to create a profile manually, and you only need to type in a few settings, like the dot name and the APN address, and then restart the device to apply the changes.
☑️ Checking the settings of the mobile Internet
Managing two SIM-maps and network selection
Xiaomi smartphone owners often use two SIM cards at the same time, which requires competent traffic management. MIUI allows you to assign one of the cards to priority for data transfer, while the second can be used exclusively for voice calls.
To switch the main map, go to the Settings menu → SIM-In the Mobile Internet section, select the SIM card you want, and it is important to note that when you switch, you may experience a short-term disconnection, which is normal behavior of the radio module.
| Parameter | Description of function | Recommendation |
|---|---|---|
| Mobile Internet | Selecting SIM for Data Transfer | Use a card with unlimited tariff |
| Default calls | Map for outgoing calls | Choose the operator with the best coverage |
| SMS default | Message map | Convenient for cards with free SMS |
| Data switching | Auto-shift in the absence of a network | Include only when necessary |
There is also a Smart Switch feature that allows the phone to automatically use the second SIM card for the Internet if the main signal is missing, which is in advanced mobile network settings and can be useful when traveling in regions with unstable coverage.
How to save traffic with two SIM cards?
Advanced Wi-Fi settings and speed optimization
For users who want to make the most of their connection, MIUI offers a number of advanced tools. In the Wi-Fi menu, clicking on the arrow next to the name of the connected network, you can see detailed information about the frequency and speed of the connection. Here you can also find the Wi-Fi Assistant feature, which automatically switches the phone to the mobile Internet if the wireless signal becomes too weak.
The important aspect is the choice of frequency range. Modern routers support the bands 2.4 GHz and 5 GHz. the former provides more coverage, but less speed, while the latter is ideal for streaming video and games, but has a shorter range. Xiaomi smartphones are able to automatically choose the optimal frequency, but if necessary, priority can be set manually in the settings of the router.
⚠️ Note: The Wi-Fi Assistant feature can consume your mobile traffic even when you’re connected to your home network, so watch your limits settings.
Another useful option is generation. QR-Instead of dictating a complex password, you can show the screen of the phone, and the guest can connect by scanning the code with the camera. MIUI It does not require the installation of third-party applications.
💡
For maximum download speeds, temporarily disable the Two Wi-Fi feature (if active) so that the phone uses only one communication channel without aggregation attempts, which sometimes causes conflicts on older routers.
Diagnostics and Solving Connection Problems
Even the most reliable devices sometimes face connectivity problems when the network icon is there and the Internet is not working. The first step should always be a banal but effective smartphone reboot, which clears the cache of network services and resets the temporary errors of the radio module.
If the reboot didn't work, check the date and time. Incorrectly set times can cause security certificate errors, which can prevent browsers and applications from establishing a secure connection. Make sure that the settings activate the option to Use Network Time.
- 🔄 Reset your network settings to factory settings (not to be confused with a full phone reset).
- 📡 Check if flight mode is on accidentally or on the schedule.
- 🔒 Make sure you're on the account. SIM-Cards have funds and the traffic limit is not exhausted.
- 🛡️ Turn it off. VPN Proxy servers that can block the connection.
When mobile internet is not working and Wi-Fi is working, it makes sense to check the APN settings again. Sometimes operators change the settings of access points, and the old settings no longer apply. Creating a new access point from scratch often solves the problem faster than editing the old one.
💡
90% of connection problems are solved by restarting your device or re-entering your Wi-Fi password, so don’t rush to bring your phone to the service.
Security and privacy when using the network
When you connect to the Internet, you become part of a global network where security is important. Xiaomi smartphones have a built-in mechanism to protect against malicious networks, which warns the user when trying to connect to dangerous Wi-Fi. However, relying on automation alone is not worth it, especially when using public networks.
It is recommended to use the random function MAC-The address that is available in the settings of each Wi-Fi network, which prevents your device from being tracked by a unique hardware identifier when you are in public places. MAC-address so as not to configure filtering on the router again.
Also worth paying attention to is application permissions. Many programs require network access to work, but some may use it in the background to transmit advertising data. → Data transfer can be denied to specific applications access to the Internet via Wi-Fi or mobile network.
