The situation when the smartphone Xiaomi Redmi suddenly stops seeing the home network or hangs endlessly at the "Obtaining IP address" stage, familiar to many users of the ecosystem MIUIThis problem can occur after a scheduled operating system update or for no apparent reason, rendering the device useless and unable to access the internet. Most often, the problem stems from a software conflict with network modules or incorrect router settings that the phone cannot automatically handle.
Before taking your gadget to a service center, it's worth ruling out simple software errors that can be easily fixed yourself. Security protocol, power saving settings, and even accidental changes to your router can block your connection. In this article, we'll detail a step-by-step process to restore stable internet access to your device using proven diagnostic methods.
Basic diagnostics and module reboot
The first step should always be the basic, but often overlooked, procedure of rebooting the hardware. In the operating system Android, on the basis of which the shell works MIUINetwork drivers can accumulate cache errors. Simply turning your smartphone off and on again can clear temporary files and re-initiate the handshake with the router. If this doesn't help, you should reboot the router itself by unplugging it for 15-20 seconds.
Users often forget about the "Airplane Mode" feature, which forcibly disables all radios. Enabling this mode for 10-15 seconds and then turning it off acts as a "soft reset" for the Wi-Fi antenna. This is especially effective if the phone indicates that a network is found, but a connection fails.
Pay attention to the behavior of other devices in your home. If your laptop or tablet also can't see the network, the problem isn't with your phone. Xiaomi, but rather the problem lies with your provider or the router itself. If you have internet access on other devices, the conflict is localized in your smartphone's settings.
⚠️ Attention: If after rebooting the phone does not see any Wi-Fi networks at all (the list is empty), there may be physical damage to the antenna module or a cable that has come loose after a fall.
It's important to check if you have any data or power saving features enabled, which could be blocking background connections. In newer versions MIUI Power-saving algorithms are aggressive and may put the Wi-Fi module to sleep at inopportune moments. Disable "Ultra Battery Saver" mode and see if this improves the situation.
☑️ Primary network diagnostics
Forget network and re-pair
One of the most common reasons why Xiaomi Redmi If your Wi-Fi connection fails, there may be a conflict with saved connection profiles. Over time, your phone's memory accumulates network data, passwords, and encryption configurations, which may no longer match your router's current settings. For example, if you change your router password or change the encryption type from WPA2 on WPA3, the phone may try to use old data, going into a crash cycle.
To resolve this issue, you need to completely delete the network profile. Go to Wi-Fi settings, tap your network name, and select "Delete" or "Forget this network." Then, find the network again in the list of available networks and enter the password. This action forces the phone to re-authorize and receive a fresh one. IP address from the router's DHCP server.
Sometimes changing the network name (SSID) on the router itself helps. If you rename the network, the phone will treat it as a completely new device and create a clean connection profile without any legacy errors. This is especially true if you recently updated your router's firmware or replaced it.
There's a caveat with the "Private MAC Address" feature, which was introduced in Android 10 and above. Some routers, especially older models, may block connections from devices with random MAC addresses. In your phone's Wi-Fi settings, try changing the "Privacy" setting from "Use randomized MAC address" to "Use device MAC address."
Why does MAC address randomization cause problems?
Some proprietary router filtering systems are configured to work only with real physical addresses. When Xiaomi generates a virtual address to protect privacy, the router may perceive this as an unauthorized access attempt or simply not know how to assign access rights to the new "guest," even if the password is entered correctly.
Date, time, and region settings
It might seem like a non-obvious parameter, but an incorrect date and time often cause connection failures to secure networks. Security protocols WPA2/WPA3 and encryption certificates are sensitive to time desynchronization. If your Xiaomi Redmi The date is off by several years, the handshake with the security server won't work, and the phone will return the error "Failed to connect."
Check that the "Use network time" option is enabled. It's best to set automatic synchronization so your phone gets the exact time from your mobile operator. Also, make sure your time zone matches your geographic location.
Regional settings also play a role. Some countries restrict the use of certain Wi-Fi channels (for example, channels 12 and 13 in the 2.4 GHz band). If your phone is set to the US region and your router is on channel 13, your smartphone simply won't see the network. Try temporarily changing the region in your phone's settings or force channels 1-11 in your router's settings.
Reset network settings and DNS configuration
If standard methods don't help, you should reset your network settings. This will return all Bluetooth, mobile data, and Wi-Fi settings to factory defaults. It's important to understand that this won't delete your personal files, photos, or contacts, but you will have to re-enter passwords for all Wi-Fi networks and re-pair your Bluetooth headsets.
You can perform a reset through the menu Settings → Connection and sharing → Reset Wi-Fi, mobile networks, and BluetoothAfter this procedure, the phone will be "clean" in terms of network interactions, which often solves problems with hidden driver conflicts.
Another common issue is incorrect operation of the provider's DNS servers. The phone may connect to the router, but pages won't load, or the connection will constantly drop. In this case, setting up static DNS addresses, such as those from Google or Cloudflare, can help.
To change your DNS, go to your Wi-Fi settings, click the arrow next to your network, scroll down to "IP Settings," and switch from "DHCP" to "Static." Enter the following values in the DNS 1 and DNS 2 fields:
- 🌐 DNS 1:
8.8.8.8(Google Public DNS) - 🌐 DNS 2:
1.1.1.1(Cloudflare) - 📶 Gateway: Enter your router's address (usually 192.168.0.1 or 192.168.1.1)
- 🔢 Network prefix length:
24
Problems with DHCP and static IP
One of the most annoying errors on Xiaomi devices is the endless IP address acquisition. This means the phone tries to contact the router, but it either doesn't respond, or the assigned device is already taken by another device on the network. On a local network, each device must have a unique identifier. If there's an address conflict, the connection is blocked.
Manually assigning a static IP address may be a solution. You can enter the address manually in the same menu where you changed the DNS (IP Settings → Static). Routers typically assign addresses in the range of 192.168.1.2 to 192.168.1.254. Try selecting an address at the end of the range, for example, 192.168.1.200to avoid interference with main devices.
⚠️ Attention: Make sure the IP address you select isn't already in use by another device. It's best to assign static addresses outside the DHCP range specified in your router's settings.
It's also worth checking your router settings. If you have many smart devices connected (lights, sockets, cameras), the DHCP address pool may be exhausted. In this case, you'll need to increase the range of addresses allocated in the router settings or reduce the lease time to release addresses from devices that are currently offline.
Diagnostics of the 2.4 GHz and 5 GHz frequency ranges
Modern routers often operate in two bands: 2.4 GHz and 5 GHz. Not all models Xiaomi RedmiMost phones, especially budget or older ones, support the 5 GHz frequency. If your router only broadcasts on this frequency (or has combined them under a single name with 5 GHz as the priority), an older phone may simply not see the network or be unable to connect to it.
It is recommended to separate networks in the router settings by giving them different names, for example, Home_WiFi_24 And Home_WiFi_5GTry connecting your phone to a 2.4 GHz network. This range has better wall penetration and is more compatible with devices.
On the other hand, if you're very close to the router and the 2.4 GHz network is congested by neighbors, your phone may attempt to connect to 5 GHz, but the signal will be unstable due to the propagation characteristics of that frequency. The table below summarizes the key differences to help you choose the right network for troubleshooting.
| Parameter | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Transfer speed | Up to 450 Mbps | Up to 1300 Mbps and higher |
| Penetration ability | Tall (breaks through walls well) | Low (does not pass through obstacles well) |
| Airtime congestion | High (a lot of interference from neighbors) | Low (cleaner ether) |
| Compatibility | Works on all devices | Only on 5G-enabled devices |
Third-party apps and factory reset
If software settings don't help, third-party applications interfering with the network stack may be the cause. Antiviruses, VPN services, ad blockers, or internet speed boosters can all be blocking the connection. Try uninstalling recently installed applications or temporarily disabling your VPN and antivirus.
It's also worth checking for system updates. Xiaomi sometimes releases patches that fix network module bugs. Go to Settings → About phone → MIUI version and check for updates.
As a last resort, if all else fails, the only drastic option is a full factory reset. Before doing this, be sure to back up all important data, as this will return your phone to its factory-fresh state. This eliminates any software errors caused by users or malware.
Can a virus block Wi-Fi on a Xiaomi?
Yes, some types of malware can modify system files responsible for network connections or redirect traffic, resulting in connection failure. Scan your phone with an antivirus or use MIUI's built-in security scanner.
Why does Wi-Fi work but it says "No Internet Access"?
This means there's a connection between the phone and the router, but the router can't access the external network. The issue could be with the provider's cable, an outstanding balance with the operator, or the PPPoE/Static IP settings on the router itself.
Does the case affect signal reception?
Metallic cases or cases with magnetic closures can block the antenna signal, which is often located at the top or bottom of the case. Remove the case and check the signal strength.
Is it worth reflashing your phone if Wi-Fi doesn't work?
Reflashing the firmware may help if the problem is a software glitch. However, if the issue is hardware-related (like a burned-out Wi-Fi module), reflashing the firmware won't help, and in the worst case, it may hinder diagnostics at a service center.
