Owners of smartphones and tablets Xiaomi, Redmi or Poco often face an unpleasant situation when the device stops connecting to the wireless network. IP-The address, and the Internet is not available, and this problem can occur suddenly, for no apparent reason, or after a firmware update. MIUI hyperos.
The problem is that your gadget can't properly "agree" with the router to allocate a unique network ID, without this address, data exchange is impossible, often the culprit is a failure in the DHCP protocol or address conflict on the local network.
Don't panic or take the device to the service center. In most cases, you can fix the IP configuration error yourself by doing several sequential steps, and we'll take a look at all the effective methods, from simple reboots to manually configuring network settings.
Why is there an error of receiving IP-address
The fundamental reason is that the handshake process between the client (your phone) and the server (router) is broken. When you select the network, the device requests an address, but the router either does not respond or sends an address that is already occupied by another device. The Dynamic Host Configuration Protocol (DHCP) is responsible for automatic address distribution, and failure is the most common culprit.
Another common scenario is a pool overflow: If you have a lot of Xiaomi Home smart devices, light bulbs, cameras and phones at home, the range of available addresses on the router may run out, in which case new gadgets simply have nothing to give away, and outdated WiFi drivers or cached network data that contain errors can also cause the problem.
Security systems sometimes conflict. Antivirus programs or the built-in MIUI firewall can block a request for an address, deeming it suspicious. In addition, incompatibility of encryption standards (for example, switching from WPA2 to WPA3) also leads to the phone seeing the network but not being able to connect.
⚠️ If the error only appears on one particular network and everything works on others (such as work or friends), the problem is 90% in your home router settings, not in the smartphone itself.
Understanding the nature of the bug helps you choose the right treatment, and if you've had a malfunction after you upgraded your system, it's probably a software conflict, and if you've had a phone fall or you've been exposed to moisture, you might have a hardware failure on your communications module, although it's less common.
Basic methods of network reset and reset
The simplest and often ignored way is to completely reboot the chain of devices, not just turn off the screen, but reboot the system, which clears the RAM and resets temporary network services that may have been getting stuck.
The second critical step is to reboot the router, and even if it's working normally, its internal NAT table or DHCP pool could overflow. Turn the router off power for 30-60 seconds, then turn it on again and wait for the indicators to load fully.
If a simple reboot didn’t work, try Forget Network, which deletes the saved password and all configuration files associated with a particular SSID, and then connects to the new network from scratch.
- 📱 Go to Settings. → Wi-Fi.
- 🗑️ Click on the arrow next to your network name and select Delete or Forget Network.
- 🔑 Enter the password again and try to connect.
In some cases, switching between frequency bands helps. If your router is dual-band, try connecting to a 5GHz network instead of 2.4GHz or vice versa. 2.4GHz frequency is more long-range, but often overloaded by neighbors, causing address collisions.
Manual adjustment of static IP-address
When automatic address acquisition doesn't work, the method is to manually prescribe the parameters. DHCP-You need to know the gateway address (usually the router's address) that you can look at on another connected device.
To go manual, open your WiFi settings, tap your network (or the arrow next to it), and find the IP Settings option. The default is DHCP, it needs to be changed to Static. The system will prompt you to enter the numbers manually.
IP- Address: 192.168.1.128
Gateway: 192.168.1.1
Length of prefix: 24
DNS 1: 8.8.8.8
DNS 2: 8.8.4.4Note the third digits. If your router's address is 192.168.0.1, your phone must be on the same subnet, such as 192.168.0.150. The main thing is that the last digit (host) does not match any other device on the network. Choose a larger number, such as 100 to 200, to avoid conflicts.
💡
Use Google’s public DNS (8.8.8.8) or Cloudflare (1.1.1.1) in manual settings – this often speeds up network response and solves problems with “hanging” during the IP acquisition phase.
Static IP is a temporary but reliable solution that allows you to use the Internet while you are looking for the cause of the router's unstable operation. However, if you change networks frequently (cafe, office), remember to return the setting to DHCP mode, otherwise the Internet will not work elsewhere.
Resetting network settings on Xiaomi
If point methods don't work, you should use the nuclear option for network modules, which is network reset, which brings all the parameters of WiFi, Bluetooth and mobile data back to factory values. Importantly, this action will remove all the saved passwords from WiFi and a couple of Bluetooth devices.
On current versions of MIUI 12/13/14 and HyperOS, the path to this feature may be different, usually in the Advanced Settings section. Before performing the procedure, make sure you remember passwords from important networks or they are stored in the Mi Account cloud.
☑️ Checklist before network reset
The reset process takes a few seconds, after which the phone can restart, which corrects deep errors in the system configuration files that may have been damaged during a failed update or power failure.
Sequence of actions for discharge:
- 🔧 Go to Settings. → Connection and sharing.
- 🔄 Find the Reset point Wi-Fi, mobile networks and Bluetooth.
- ✅ Confirm the action and wait for the process to be completed.
After this procedure, the phone will be clean in terms of network connections. Try to connect to your network again. If the IP configuration error has disappeared, then the problem was the software failure of the operating system.
Router settings: DHCP and compatibility
Often the root of the evil is hidden in the settings of the router itself. Go to the router's admin panel (usually through the browser at 192.168.1.1 or 192.168.0.1). LAN or DHCP Server.
Check the size of the address pool. If the range is too small (e.g. 1 to 10) and the devices in the house are larger, new gadgets will not have enough addresses. Expand the range to 192.168.1.100 – 192.168.1.200. It also makes sense to increase the time of renting an address (Lease Time) so that devices less often request a new IP.
| Parameter | Recommended value | Description |
|---|---|---|
| DHCP Server | Enable (Included) | Must be active for auto-distribution |
| Start IP Address | 192.168.1.100 | Beginning of address range |
| End IP Address | 192.168.1.200 | End of range (maximum customer) |
| Address Lease Time | 120 minutes (or more) | Validity time of the issued address |
Another important aspect is the type of encryption. Some older Xiaomi devices are not friendly with WPA3. Try switching security to WPA2-PSK (AES), which is the most stable and compatible standard at the moment.
⚠️ Note: Changing your router settings can temporarily temporarily temporarily temporarily allow Internet access on all connected devices. Make sure you don’t break your provider’s PPPoE login/password settings unless you know them by heart.
Additional solutions and hidden MIUI functions
There are hidden optimization features and features in the MIUI shell that can interfere or help. For example, the WiFi Assistant feature may try to switch networks in the background, causing conflicts. Try disabling Wi-Fi Assistant in additional wireless network settings.
It's also worth checking the date and time. If the device has a time lost, the security certificates may not be validated, and the router will reject the connection request. Set Automatic Date and Time over the network.
Secret code for diagnosis
If nothing helps, try to change. MAC-In modern versions of Android and MIUI randomized MAC-address for each network (privacy function). Some routers block such requests. In the settings of a particular network (cog or arrow), find the item "Privacy" or «MAC-address" and select «MAC-Device address instead of random MAC».
The final argument is a factory reset of the phone, which is an extreme measure that requires backup, and if that didn't work, it's probably a problem with the physical damage to the antenna module, and you need to visit the service.
💡
Shift. MAC-addresses from random to device address often solves the problem on routers with strict filtering or software.
