The situation when Redmi 8 Pro Suddenly losing connection to the wireless network or getting stuck while obtaining an IP address can be a serious problem. A smartphone powered by the MediaTek Helio G90T processor initially boasted decent energy efficiency, but over time, software glitches or component wear can disrupt connection stability. Users often encounter a situation where the device simply ignores the router, even though other devices in the home are working properly.
Before taking your device to a service center, it's worth ruling out software errors in the operating system. MIUIIn most cases, the problem stems from a network protocol conflict or incorrect power saving settings. Below, we'll outline a step-by-step procedure that will help restore internet access without extensive system intervention.
It's important to understand that diagnostics begin with the most basic thing—checking the current settings. Sometimes, simply shaking the software is enough to get the module working again. However, if the phone won't connect to Wi-Fi Even after a reboot, a more detailed approach will be required.
⚠️ Warning: If your phone has recently been dropped or exposed to water, the Wi-Fi issue may be physical. In such cases, software solutions may not help, and opening the phone yourself will void the warranty.
Basic reboot and reset of network settings
The first and most effective step is to force reboot the communication module. Unlike a simple screen shutdown, a full system reboot Android cleans up temporary files that may have caused driver conflicts. Redmi 8 Pro This is done by long pressing the power button or through the shutdown menu.
If a simple reboot doesn't help, you'll need to reset your network settings. This will reset your Bluetooth and mobile data settings to factory defaults, deleting saved passwords and configurations. To do this, go to Settings → Connection and sharing → Reset Wi-Fi, mobile networks, and Bluetooth.
After the reset, your phone will ask for confirmation and possibly an unlock code. The system will warn you that all saved access points will be deleted. This is normal behavior and is necessary to clear the connection registry.
☑️ Primary diagnostic checklist
It's worth noting that after resetting your settings, you'll have to re-enter your home network password. Make sure you enter it correctly, taking into account the case of the letters, as authentication error often disguised as a connection problem.
Problems with the router frequency range and channel
Wi-Fi module in Redmi 8 Pro It supports both 2.4 GHz and 5 GHz bands. However, MIUI sometimes handles switching between them incorrectly, especially if the router is broadcasting the same network (Smart Connect). In this case, the phone may get stuck on the congested 2.4 GHz channel, ignoring the faster 5 GHz.
It is recommended to separate the networks on the router by giving them different names, for example, Home_WiFi And Home_WiFi_5GTry connecting to a 5 GHz network if you're close to your router. This range is less polluted by neighboring devices.
It's also worth checking the channel width. If your router's settings are set to automatically set the channel width to 40 MHz for the 2.4 GHz band, older or budget modules may not work reliably. Try setting the channel width to 20 MHz.
Why is 5GHz better for Redmi 8 Pro?
The 5 GHz band offers higher data transfer rates and is less susceptible to interference from microwave ovens and Bluetooth devices. However, it has a shorter range and is less effective at penetrating concrete walls. If your phone can't see the 5 GHz network, it may be too far from the router or in a "dead zone."
| Parameter | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Range | High | Low |
| Permeability of walls | Good | Bad |
| Speed | Up to 150-300 Mbps | Up to 866+ Mbps |
| Workload | High (neighbors, household appliances) | Low |
If you've changed your router settings, be sure to "forget" the network on your phone before reconnecting so that the device applies the new security settings and encryption protocols.
Conflict between static IP and DNS servers
A common reason why Redmi 8 Pro The error message "Connected, no internet access" is an IP address conflict. If you have a lot of devices on your network, the router may assign an address that's already taken, or the phone may attempt to use an old static address that's incompatible with the current configuration.
You need to check your IP settings. Go to the properties of the connected network, click the arrow or gear next to the Wi-Fi name. Find the "IP Settings" item and make sure the value is selected. DHCPThis will allow the router to automatically issue the current address.
If the problem persists, try setting public DNS servers from Google or Cloudflare. This often helps when your ISP is blocking access or your DNS servers are slow. In the IP settings, select "Manual" (Static) and enter "DNS 1" in the DNS field. 8.8.8.8, and in DNS 2 - 1.1.1.1.
When manually entering the IP address, make sure the gateway (router) is specified correctly. This is usually an address of the form 192.168.0.1 or 192.168.1.1An error in one digit will make connection impossible.
Impact of energy saving and background processes
operating system MIUI is known for its aggressive power-saving policy. The "Battery Optimization" feature can forcefully disable Wi-Fi if the screen is off or an app is running in the background. This often results in the phone losing its network connection after waking up.
To solve the problem, go to Settings → Battery & PerformanceFind the power saving settings and select "Unlimited" mode for Google Play system services and Android system processes. It's also worth disabling the "Wi-Fi Assistant" feature, which switches traffic to the mobile network when the signal is weak.
Sometimes third-party applications, such as VPNs or antiviruses, that create virtual network interfaces are to blame. Try temporarily disabling or uninstalling such programs to see if the connection is restored.
⚠️ Note: Disabling battery optimization may cause battery drain. We recommend reverting these settings if battery life reaches critical levels.
Firmware failure and system update
Software bugs in a specific version MIUI may cause unstable Wi-Fi drivers. Xiaomi developers regularly release security patches and bug fixes. Check for updates in the section About phone → MIUI version.
If you have a beta ROM installed, the risk of network errors is significantly higher. In this case, we recommend rolling back to a stable ROM via Recovery Mode, after backing up important data.
In rare cases, a full reset to factory settings helps (Wipe DataThis is a drastic method that deletes all user data, so be sure to back up your contacts and photos to the cloud before using it.
Wi-Fi module hardware failure
If none of the software methods helped, there is a high probability of physical damage. Redmi 8 Pro The Wi-Fi module is integrated into the main board or is a separate chip that could have become detached from its contacts during a fall. Overheating of the component, leading to its temporary failure, is also possible.
Symptoms of hardware failure include a grayed-out or inactive Wi-Fi icon in the settings, a complete failure to search for networks even after a reset, or Wi-Fi turning on for 1-2 seconds and then turning off. In such cases, diagnostics at a service center are required.
Sometimes the problem can be solved by heating the chip (reballing), but this is a temporary solution. A more reliable option is replacing the module or the entire motherboard, if repair is cost-effective.
Settings interfaces and menu item layouts may vary depending on the MIUI version (11, 12, 13, 14) and regional firmware (Global, EU, Russia). If you can't find the item you're looking for, search through your phone's settings.
Frequently Asked Questions (FAQ)
Why does Redmi 8 Pro see the network, but says "Authentication error"?
Most often, this means an incorrect password. However, if you're sure of the password, the issue may lie with the router's encryption type. Try changing the router's security method from WPA3 to WPA2/WPA2-PSK, as older modules may not work correctly with newer protocols.
What should I do if Wi-Fi turns on and then immediately turns off?
This is a classic sign of a driver conflict or hardware defect. Try booting your phone into safe mode. If the problem persists, the communication module itself or the antenna cable is likely damaged.
Can a case interfere with Wi-Fi on the Redmi 8 Pro?
Yes, if the case has a metal insert, a magnetic clasp, or is too thick, it may block the signal. Remove the case and check the reception.
Will resetting the router help if the phone won't connect?
Yes, resetting the router to factory settings will clear the list of connected clients and clear any errors in its DHCP server. Afterwards, you'll need to reconfigure the router's internet connection.
