When a Xiaomi smartphone shows a Wi-Fi icon but the Internet is not working, it irritates anyone: You are connected to the home network, the signal is full, but the pages are not loading, and messengers do not receive messages. This problem is common and can be hidden in both software failures of the MIUI operating system and in the settings of the router itself. Often the system automatically detects no access and gives a warning, but sometimes the device continues to hang in a state of “connected, without access to the network”.
Before you panic or bring your phone to the service, you need to do a basic diagnosis, and in most cases, the cause is conflict. IP-addresses or misplaced DNS-The RAM of the device may have been overflowing with the cache of network services, which blocks normal data exchange, and temporary failures at the provider cannot be ruled out, although in this case the problem would have manifested itself on other devices.
We'll look at a step-by-step approach to help you reset your connection, learn how to reset your settings, change your encryption settings, and check your static IP. Android has flexible diagnostic tools that users often ignore, and follow the instructions to fix 90% of all possible problems without having to flash it again.
Diagnostics and initial network checks
The first thing you need to do is make sure that the problem is localized in your smartphone, not in the outside world. If you have other gadgets connected to the same access point, check them. If there's no Internet everywhere, it's not the phone, it's the router or the provider, and then you should reboot the router, disconnecting it from power for 10-15 seconds.
If other devices are working normally and Xiaomi is “persistent,” check the status of the service with the operator. Sometimes access is blocked due to the end of the tariff period or technical work on the line. Make sure that there are funds on the balance sheet, and try to open any site via mobile Internet (3G/4G), temporarily turning off Wi-Fi, which will help to understand whether the network module of the phone works at all.
It is important to pay attention to the date and time in the system. Incorrect timing often leads to errors in security certificates, which makes browsers and applications unable to establish a secure connection. Go to Settings → Additional → Date and Time and enable automatic synchronization. This is a simple but often overlooked step that solves the problem of “no access” in many cases.
And remember, physical proximity to the router, because the signal can be strong enough to connect, but it's not strong enough to transmit data consistently, especially at 5 GHz. Walls, mirrors, and appliances can interfere. Try to get closer to the source and see if access comes.
Basic actions: reboot and forget the network
The easiest and most effective way to solve many software errors is to reboot the device, which clears RAM and resets temporary network configurations that may have been corrupted. Don't ignore this step, thinking it's too banal. In Android, network services can freeze, and a full restart often brings them back to life.
If the reboot didn't work, try "forgetting" the problem network, which will delete the saved connection profile with all its parameters, including possible authentication errors. Go to the Wi-Fi settings, click on your network name and select "Delete" or "Forget" and then connect again, entering the password.
☑️ Checklist of rapid diagnosis
When you reconnect, the system will ask for a password again. Make sure you enter it correctly, considering the register of letters. Sometimes users accidentally change the layout or do not notice any extra characters. MAC-Addresses that may block access to new or modified devices.
⚠️ Note: If after deleting the network, the phone continues to write "Authentication Error" or "Receiving" IP-The problem may be incompatibility of encryption protocols. Try changing the type of security on the router (for example, with the help of a computer). WPA3 on WPA2), If you have access to it.
Static IP and DNS configuration
Often the reason for the lack of access lies in the conflict. IP-Addresses when the router gives your phone an address that is already occupied by another device on the network, in which case it helps to translate the settings. IP dynamically (DHCP) It fixes the address behind your device and eliminates routing confusion.
To do this, go to the Wi-Fi settings, click on the arrow or your network name to reveal additional settings. IP" and change the meaning of c DHCP You'll need to type in a few values manually, and usually you just need to change the last number in the field "IP-address" to any free number from 2 to 254 (e.g. 192.168.1.55).
What DNS servers should I use?
Pay special attention to the fields "DNS 1" and "DNS 2.” Providers often provide their own services DNS-And if you replace them with public addresses from Google or Cloudflare, you can significantly speed up the response of the network. DNS 1 enter 8.8.8.8 and in DNS 2 — 8.8.4.4.
Once you've entered all the settings, save the settings. The phone will reconnect to the network. If the Internet came along, then the problem was dynamic address allocation, or DNS, which is especially relevant for older routers or networks with more connected devices.
Reset network settings and advanced settings
If manipulation with IP-And you have to go to a more radical, but more secure, network reset, and it's important to understand that this operation won't delete your personal files, photos or contacts, and it will only affect stored Wi-Fi networks, Bluetooth passwords and mobile network settings.
To perform the reset, go to Settings → Connection & Sharing → Reset Wi-Fi, mobile networks and Bluetooth. Confirm the action and wait for the process to complete. After that, the phone will restart, and you will have to re-enter passwords from all your Wi-Fi networks.
| Parameter | What's being dropped | Impact on data |
|---|---|---|
| Resetting network settings | Wi-Fi, Bluetooth, Mob. | User data is stored |
| Resetting all settings | All system settings | User data is stored |
| Full reset (Wipe) | The whole system and data | Complete deletion of data |
| Resetting applications | Application settings | Application data may be lost |
In the advanced Wi-Fi settings, you can also find the item "Use random" MAC-Address. In some cases, routers block access to randomized devices MAC-Try switching this option to "Use" MAC-Device address in the settings of a particular network.
💡
Network reset is a secure procedure that eliminates deep software conflicts of network modules without affecting the user’s personal files.
Problems on the side of the router and provider
It is not excluded that the smartphone is working, and the problem lies in the configuration of the router. Overflowing memory of the router, outdated firmware or overheating can lead to the fact that new devices do not get access to the Internet. Try to restart the router through the web interface or physically by turning off the power.
Check the number of connected customers. If the device limit on your network is exhausted, the new gadget will not be able to get the new one. IP-Also worth checking is whether parental control or filtering is enabled. MAC-Addresses that can block Xiaomi’s access to the global network, leaving local access to the network.
⚠️ Note: If a router has been running for several years without interruption, it may have accumulated errors in logs.
In some cases, providers use a link to MAC-If you change your router or reset your router, the Internet may not work until you clone it. MAC-address of the old device or do not call the provider to update the data.
MIUI specifics and system constraints
MIUI has an aggressive energy saving system that can limit background activity of network services. Check if traffic restriction is worth limiting for system applications. Go to Settings → Applications → All applications, find Wi-Fi or System Services and make sure that network access is unlimited.
It is also worth paying attention to the established VPN-They can intercept network traffic and block the connection if their servers are unavailable or there is a certificate conflict.
In rare cases, the problem may be due to the frequency of Wi-Fi channels. if the router is running in the 5 GHz band on channels that your smartphone does not accept well (for example, DFS-There may be permanent breaks, try settings on the router to lock the channel to 36, 40 or 44, or switch to 2.4 GHz to check for stability.
💡
Use the Wi-Fi Analyzer app (or analogs) to see the congestion of channels in your home. Choosing a free channel on your router will greatly improve connection stability.
