It's extremely common for a Redmi smartphone to successfully connect to your home network, display the Wi-Fi icon, but still not connect to the internet. This condition is often referred to as an "authorization error" or "addressing conflict." The phone's screen shows that the radio module is working properly and a connection to the router is established, but data packets aren't transmitted further to the ISP. Users see the status "Connected, no internet access" or an endless wait for pages to load in the browser. This doesn't always indicate a malfunction of the smartphone itself.
Device owners Xiaomi, Redmi And Poco People encounter this issue due to aggressive system optimization in MIUI and HyperOS. The operating system may incorrectly detect signal quality or save incorrect network profiles. Sometimes the cause lies in a malfunctioning DHCP server in the router, which simply fails to assign the correct IP address to the phone. In other cases, static DNS settings, which may have become corrupted after a firmware update, are to blame. Understanding the nature of the failure is the first step to restoring the network.
Before taking your device to a service center, it's worth checking the basics. Make sure the internet connection is stable on other devices using the same network. If the problem is only with your phone, then it's a problem with its settings. If the internet connection drops on all devices, the problem lies with your ISP or router. In this article, we'll cover specific troubleshooting steps for this ecosystem. Xiaomi.
Basic diagnostics and service restart
The simplest and most often overlooked method is a complete reset of the network stack. Many users simply turn Wi-Fi off and on using the slider in the Wi-Fi settings, but this isn't enough to reset the network services cache. Android. A deeper action is required. Go to Settings, find the item Wi-Fi Click the gear icon next to your network, then select "Delete" or "Forget Network." This action will erase the saved password and current connection settings.
After deleting the network profile, reboot your smartphone. Don't skip this step, as processes may remain in RAM that are blocking reconnection. After turning on the phone, try reconnecting by entering the password. If the icon appears but the internet still doesn't work, the problem is deeper. There may be a software issue with the communication module.
It's also worth checking to see if airplane mode is accidentally enabled. Sometimes the system gets stuck in this state, and even after turning off airplane mode, the Wi-Fi module doesn't activate correctly. Swipe down from the top of the screen to open the Control Center and make sure airplane mode is turned off. If the Wi-Fi icon is lit but pages aren't loading, try opening a website in incognito mode. This will eliminate the possibility of browser cache or ad blocker extensions interfering.
Problems with IP addressing and DNS servers
One of the most common reasons why Wi-Fi is connected but there's no internet on a Redmi is an IP address conflict or incorrect DNS settings. The router acts as a DHCP server, distributing addresses to all devices. If the address pool is mixed up or the phone receives an address already taken by another device, access to the global network is blocked. The default Wi-Fi settings on the Redmi are set to obtain an IP address automatically, but manual settings can sometimes help.
To check and change settings, go to the Wi-Fi menu, click on the name of your network (or the arrow to the right of it). Find the section IP settingsBy default it is there DHCPTry switching to StaticYou will need to manually enter the IP address (usually 192.168.1.X or 192.168.0.X, where X is a number from 2 to 254), gateway (router address), and network prefix length (usually 24). A critical point is the registration of DNS servers: use 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare), since the provider's DNS may not respond.
⚠️ Attention: When manually setting up a static IP, make sure the chosen address isn't already in use by another device on the network. It's best to choose numbers at the end of the range, such as 192.168.1.200, to avoid conflicts with guest phones or smart devices.
Changing DNS servers often solves the problem when the router is working properly, but domain names aren't resolving to website IP addresses. This happens due to provider issues or when using parental controls. After entering the new DNS servers, click "Save" and reconnect. If the internet is restored, then the problem was precisely the inability to resolve website addresses.
Reset network settings on Redmi and Poco
If manually adjusting the IP address doesn't help, you should try a more radical but effective method: a complete network reset. This will return all Wi-Fi, mobile data, and Bluetooth settings to factory defaults. It's important to understand: this action will not delete Your personal files, photos, and apps will be deleted. Only saved Wi-Fi network passwords and Bluetooth pairing settings will be erased.
You can perform a reset through the settings menu. The path may vary slightly depending on the MIUI or HyperOS version. Typically, it's located at: Settings → Connection and sharing → Reset Wi-Fi, Mobile Networks, and BluetoothIn some firmware versions, this item is hidden in the menu. Advanced settingsA warning will appear on the screen informing you that all network settings will be deleted. Confirm the action and wait for the interface to reboot.
After this procedure, the phone will be "clean" in terms of network configurations. You will need to re-enter your home network password. Often, accumulated software junk in system configuration files prevents a proper handshake with the router. If the problem persists after the reset, the issue is not with the phone's software settings, but with compatibility issues with encryption standards or hardware.
☑️ Checklist before resetting the network
Router settings and encryption standards
The problem may not be with the phone, but with how the router communicates with devices. XiaomiModern smartphones support Wi-Fi 5 (802.11ac) and Wi-Fi 6 (802.11ax) standards, as well as 2.4 GHz and 5 GHz frequencies. Sometimes the router's automatic channel or mode selection causes a conflict. Go to the router's web interface (usually 192.168.0.1 or 192.168.1.1) and check the wireless settings.
Try changing your security mode. If you have mixed mode enabled WPA2/WPA3, your Redmi phone may try to connect via a less secure protocol, while your router blocks access for security reasons, or vice versa. Try setting it strictly WPA2-PSK (AES)This is the most compatible standard. It's also worth disabling MAC filtering if it's enabled, as your phone may be blocked at the router level.
Another important parameter is frequency separation. If your router broadcasts the same network with the same name for 2.4 GHz and 5 GHz (Smart Connect), try separating them by giving them different names (for example, Home_2G and Home_5G). Then connect your Redmi to the 2.4 GHz network to test. The 5 GHz frequency has a shorter range and penetrates walls less effectively, which can create the illusion of a connection without actually transmitting data.
| Parameter | Recommended value | Why is this important? |
|---|---|---|
| Security mode | WPA2-PSK (AES) | Maximum compatibility with old and new devices |
| Wi-Fi channel (2.4 GHz) | 1, 6 or 11 | These channels do not overlap, reducing interference levels. |
| Channel width | 20 MHz (for 2.4 GHz) | Increases signal stability in apartment buildings |
| DHCP Lease Time | 120 minutes (or more) | Prevents frequent IP changes and connection breaks |
⚠️ Attention: Router interfaces from different manufacturers (TP-Link, ASUS, Keenetic, MikroTik) vary greatly. The exact names of the options may vary, but the meaning of the settings (Security Mode, Channel Width) remains the same.
What is MAC addressing and randomization?
Modern versions of Android use a random MAC address for each Wi-Fi connection for privacy purposes. Some older routers or configured filters may block these "changing" addresses. In the Wi-Fi settings on Redmi, you can select "Use device MAC address" instead of "Random MAC address," which often resolves the access issue.
The Impact of VPNs, Proxies, and Third-Party Apps
Users often forget that they have apps installed to bypass blocking or speed up the internet. VPN services Proxy servers can create virtual network interfaces that intercept traffic. If the VPN server is unavailable or the connection to it is lost, and the app remains running in the background, the entire internet connection on the phone can freeze, even if Wi-Fi is technically connected.
Check your list of installed apps. If you're using a VPN, try disabling it completely or uninstalling it. Also, go to the connection settings for a specific Wi-Fi network (by clicking the gear icon or arrow next to the network name). Find the option Proxy (Proxy). There should be a value there. No (None). If any address is specified there or the "Manual" mode is selected, the internet will not work, as the phone is attempting to send requests through a non-existent server.
Antiviruses and firewalls can also block the connection. If you've recently installed security software, try temporarily disabling its network protection. Redmi owners should also check the built-in antivirus software. SecuritySometimes its Wi-Fi Protection feature may mistakenly flag a secure home network as risky and restrict data transfer.
Hardware faults and the Wi-Fi module
If software solutions, resetting settings, and checking the router fail, a hardware issue cannot be ruled out. The Wi-Fi module in Redmi smartphones is integrated into the main board. Dropping the device, getting wet, or simply over time can cause the antenna cable to become loose or the chip itself to fail. A hardware failure is often indicated not only by a lack of internet, but also by a grayed-out (inactive) Wi-Fi icon in the settings or its complete disappearance.
Try moving your phone closer to the router. If the internet connection appears 10 centimeters away from the antenna, but disappears 1 meter away, the antenna module is damaged or corroded. It's also worth checking to see if the top of the phone is overheating when attempting to connect. Overheating can cause the radio module to throttle (decrease performance) and eventually shut down.
In rare cases, a firmware update can help. If the problem appears after a system update, the new version may contain a bug. You can try rolling back to the previous version or, conversely, installing a more recent build. However, if the phone is under warranty, it's best not to tamper with the software yourself; instead, take it to an authorized service center.
Why did my Wi-Fi connection disappear after updating MIUI?
System updates often change network drivers or security policies. After an update, old configuration files may conflict with the new rules. Solution: perform a full network reset (as described above) or forget the network and reconnect. Clearing the Google Play Services cache can sometimes help.
Can date and time affect connection?
Yes, it can. If the date on your phone is incorrect (for example, if it's set to 2020), website and router security certificates will be invalid. SSL connections won't be established, and the browser will display "No internet connection." Check if automatic time detection is enabled in your settings. Date and time.
What should I do if only rebooting the router helps?
This indicates that the router's DHCP table is full or that it's overheating. The router stops issuing new IP addresses. Try increasing the address pool in the router settings (for example, from 192.168.1.100 to 192.168.1.250) or upgrade to a more powerful device if you have a lot of smart devices.
