Modern Xiaomi and Redmi smartphones have long ceased to be just devices for calls, becoming powerful multimedia centers that require constant connection to the global network. Lack of access to data is often a critical problem, especially when you need to urgently use a navigator or messenger. Owners of budget and medium-budget models often face the nuances of configuring the MIUI interface, which has its own characteristics of managing network modules.
The process of activating data transfers can vary depending on the version of the Android operating system and the manufacturer’s shell. Sometimes one swipe across the screen is enough, and in other cases, you need to manually register the parameters of the operator. In this article, we will discuss all possible scenarios, from simple actions to complex settings of access points, so that your gadget will work again at full speed.
It is important to understand that failures can be either software-based or a result of physical damage to the antenna or a computer. SIM-Before you bring the device to the service, you should eliminate trivial configuration errors. Below are step-by-step instructions that will help restore the connection in most cases.
⚠️ Note: Before you start a deep network setup, make sure that your account has funds or a tariff plan is activated, as technical settings will not help if the service is blocked by the operator.
Quick activation through the control panel
The most obvious and quick way to start data transfer is to use a notification curtain, which works equally well on all models, whether it is the old Redmi Note 8 or the newest flagship, and you need to swipe your finger from the top edge of the screen down to reveal the quick settings menu.
In the icon list that opens, look for an icon that says "Mobile Internet" or a symbol for two arrows. If the icon is grey, click on it once to become active (usually blue or green). Some versions of MIUI may require a swipe left or right to find the desired button on the second page of the widgets.
Sometimes the system asks for confirmation of the action, especially if the SIM card in the device two, in which case the screen will appear a pop-up window, where you need to choose which SIM card to go through traffic. SIM-Cards are critical if you have unlimited rates on only one of the numbers.
If you don't have the Internet after you turn on the icon in the curtain, look at the indicators in the upper right corner, and they should show up with the letters 4G, LTE or H+, and if only E or G is on, then the network coverage in your area is weak and the speed will be extremely low.
Setting up mobile Internet in the smartphone menu
More detailed control of network connections is through the main settings menu, where the user can control not only the onset, but also the priorities of networks, as well as traffic limits «SIM-maps and mobile networks».
In the menu that opens, you'll see a list of SIM cards installed, and if you click on the one you want, you'll be taken to the control sub-menu, and you'll need to activate the "Use Mobile Network" switch, and without that, the phone won't try to connect to the operator's tower, even if the sliders in the curtain are active.
☑️ Checking network settings
For maximum speed, it is recommended to choose 4G or 5G mode, if your tariff and terrain support this. Forced 3G or 2G mode only may be required in areas of poor reception, but the speed will be much lower.
Also in this section, the Traffic Limit feature is common: If it's enabled, the system can block internet access after reaching a certain consumption threshold. Check the limit settings to make sure it's not too low for your plan.
⚠️ Note: Do not install the network type "Only" 4G», If you're often on the move or in buildings with thick walls, it can cause your phone to lose its signal where it's not. 3G It still catches you and you will be left without communication at all.
Manually configuring APN access points
The most common reason for not having internet when you have a signal is that you don't configure the APN hotspot, and these parameters tell the phone which gateway to access the network, and they usually come automatically with a text message from the operator, but sometimes you have to manually prescribe them.
To get into the settings menu, go down the Settings path. → SIM-maps and mobile networks → Choose. SIM → Access points (APN). If the list is empty or the current point is not working, click the button “New access point” or “Reset to standard».
Manual creation requires you to enter the data provided by your operator, usually you need to fill in the fields "Name" and "Access Point (APN)". The remaining fields, such as username and password, are often left blank or filled in by the operator's template.
| Operator. | The name of the dot (Name) | Access Point (APN) | Note |
|---|---|---|---|
| MTS | mts internet | internet.mts.ru | Login/password: mts |
| MegaFon | megafon | internet | No login or password. |
| Beeline | Beeline Internet | internet.beeline.ru | Login/password: beeline |
| Tele2 | Tele2 | internet.tele2.ru | No login or password. |
Once you have entered all the data, be sure to click the menu (three dots in the corner) and select Save. Then remember to tick the created dot to activate it. Without saving, the changes won't take effect, and the Internet won't work.
What to do if the access point is not saved?
Solving problems with Wi-Fi connection
Wireless Wi-Fi is the main source of traffic for most Xiaomi users.If the smartphone does not connect to the router or writes "Connected, without Internet access", the problem may lurk in the conflict. IP-addresses or settings DNS.
The first thing you need to do is forget the network. Go to your Wi-Fi settings, click on your network name, and select Delete or Forget. After that, enter your password. This often solves the problem of desynchronizing encryption keys.
If a simple reconnection didn’t help, try changing the settings. IP. In the menu of the selected network, click "Settings" IP» and switch mode with DHCP Static. You can prescribe it here. DNS-manual servers, such as those from Google (8.8.8.8), which often speeds up network response.
It is also worth checking whether the router is not included filter on the MAC-On the phone, you can find this address in the Settings section. → The phone. → General information or Wi-Fi connection status. If the filter is active, add MAC-smartphone address in the white list of the router.
💡
Use the Wi-Fi Assistant feature in Xiaomi settings, which allows you to automatically switch to mobile Internet if the Wi-Fi network is unstable or does not have access to the WAN.
Resetting network settings and other methods
When standard methods fail, the radical but effective way is to reset your network settings, which won't delete your personal photos, contacts or apps, but will return all network settings to factory values, you'll have to re-enter Wi-Fi passwords and configure Bluetooth devices.
To perform the reset, go to Settings → Connection and Sharing → Reset Wi-Fi, mobile network and Bluetooth. Confirm action and wait for modules to reboot. This often resolves problems with the “glutch” communication module after system updates.
Another important aspect is the date and time: If the phone has a time settings down, the security certificates will not work, and the Internet will not connect anywhere, make sure that the date and time settings are ticked with the "Use Network Time" box.
⚠️ Attention: Resetting network settings will also delete all saved Bluetooth device passwords.Make sure you know the passwords from your wireless headphones or speakers to plug them back in again.
Diagnostics of hardware problems
If software methods are powerless, you have to think about the physical state of the device. SIM-card, especially if it is old-style or has scratches on contacts. Try installing the SIM card in another phone or replacing it in the cabin of the operator with a new one with support 4G.
There may also be problems with the antenna module inside the smartphone, so if the device falls or falls into the water, the antenna contact with the board may be disrupted, in which case the phone may indicate the presence of a network, but the data transmission will be impossible or extremely unstable.
You can check for hardware errors through the engineering menu. Type ##6484## in the call. In the menu that opens, select Sim or Wireless for testing. If the test shows an error (Fail), you will likely need repairs at the service center.
💡
If resetting and replacement SIM-The cards did not help, and the engineering test gives an error, the problem is hardware in nature and requires the intervention of specialists.
