A situation when your smartphone Redmi Suddenly losing track of the home network or staying stuck on the "Obtaining IP address" status forever can be frustrating for any user. This is a common problem in the ecosystem. Xiaomi, which is often rooted not in hardware failure, but in a software conflict or network settings glitch. In most cases, restoring internet access takes no more than 10-15 minutes if you follow the steps consistently.
Modern routers and smartphones use complex encryption protocols, and the slightest mismatch in parameters can lead to a connection break. Android Devices running MIUI or HyperOS sometimes manage power consumption aggressively, which can lead to Wi-Fi module shutdowns in the background. Before taking your device to a service center, it's worth checking the basic settings and ruling out software glitches.
In this article, we'll cover all possible scenarios, from simple reboots to manually setting DNS servers. You'll learn why security systems might block connections and how to properly reset network settings without losing important data. It is critically important to check the router's operating mode (2.4 GHz vs. 5 GHz), as older Redmi modules simply do not see the new frequencies.
Basic diagnostics and module reboot
The first step should always be a basic hardware check. Often, the problem lies in a simple freeze in the smartphone's network adapter or the router itself. Turn off Wi-Fi on your phone, wait 10 seconds, and then turn it back on. If that doesn't help, try rebooting the device itself. Redmi, as this clears RAM and resets temporary network configurations.
Don't ignore your router's status. Even expensive equipment can accumulate errors in its logs and overheat. Unplug the router for 30 seconds, then plug it back in and wait for all the indicators to fully load. After that, check if your phone can see the network.
⚠️ Note: If after rebooting the router the WAN or Internet indicator lights red or does not light at all, the problem is with your ISP, not your Redmi smartphone.
Sometimes, forgetting the network helps. Go to Wi-Fi settings, tap your network name, and select "Delete" or "Forget." Then, re-enter the password. This forces the system to go through the handshake and authentication process again.
Checking date, time, and regional settings
One of the most common and subtle reasons for connection failure is time desynchronization. Security protocols WPA2/WPA3 Require the client device's time to match the server's time. If the date is incorrect, the security certificates are considered invalid, and the router rejects the connection.
Check the settings in the menu Settings → Additional settings → Date and timeMake sure the "Use network time" switch is enabled. If the time is set manually and differs from the actual time by even a few minutes, the network may not function correctly.
It's also worth paying attention to the region. In some firmware versions MIUI Different countries have different restrictions on Wi-Fi channel usage. If you recently changed your phone's region settings, try resetting it to the default or selecting the country that matches your location.
Router settings: frequencies and channels
Modern dual-band routers can create conflicts with older or budget models. RedmiIf your phone only supports the 2.4 GHz band and your router only broadcasts a 5 GHz network (or combines them into one using smart switching), your device may not connect.
Go to your router settings (usually at 192.168.0.1 or 192.168.1.1) and check your wireless network mode. For the 2.4 GHz band, it's recommended to set the mode to mixed (b/g/n) and the channel width to 20 MHz for maximum compatibility. For 5 GHz, it's best to select 40 or 80 MHz.
The channel number is an important parameter. In apartment buildings, the airwaves are clogged with neighboring networks, causing interference.
- 📡 For 2.4 GHz, use static channels 1, 6, or 11 - they do not overlap.
- 📡 For 5 GHz, choose channels in the 36-48 or 149-165 range, avoiding DFS channels if your phone has difficulty seeing them.
- 📡 Avoid the "Auto" channel mode if you have many networks in your home, as the router may jump frequently, causing disconnects.
⚠️ Note: Router interfaces from different manufacturers (TP-Link, Asus, Keenetic) vary. The exact names of the options may vary, so please consult the instructions for your specific router model.
What are DFS channels?
These are channels in the 5 GHz range, which are also used by weather and aviation radars. If the router detects a radar signal, it is forced to change the channel, which results in a brief loss of connection. Older Wi-Fi modules in Redmi devices may not respond correctly to such channel changes.
Reset network settings on Redmi
If simple methods don't help, it's possible that the system has accumulated network protocol configuration errors. Android has a feature called "Reset Wi-Fi, mobile data, and Bluetooth settings." This won't delete your photos, contacts, or apps, but it will clear all saved Wi-Fi passwords and Bluetooth pairings.
To perform this procedure, follow the path Settings → Connection and Sharing → Reset Wi-Fi, Mobile Network, and BluetoothClick the "Reset settings" button and confirm the action with the screen unlock code or PIN.
☑️ Checklist before resetting the network
After rebooting, your phone will be as good as new in terms of connections. Try connecting to your home network again. This method resolves the issue in 80% of software glitches.
Manual IP and DNS configuration
Sometimes the router's DHCP server can't correctly assign an address to the device, causing it to get stuck in a connection loop. In this case, manually assigning a static IP address can help. In the Wi-Fi settings menu, click the arrow next to the network name or select "Advanced."
Switch your IP settings from "DHCP" to "Static." You'll need to enter the gateway address (usually 192.168.1.1 or 192.168.0.1) and the phone's IP address, which should differ from the gateway address only by the last digit (e.g., 192.168.1.15).
| Parameter | Example of meaning | Description |
|---|---|---|
| IP address | 192.168.1.128 | Your Redmi's network address |
| Gateway | 192.168.1.1 | Your router's address |
| Prefix length | 24 | Standard value for home networks |
| DNS 1 | 8.8.8.8 | Google Server (Primary) |
| DNS 2 | 1.1.1.1 | Cloudflare Server (Backup) |
Pay special attention to your DNS servers. Providers often use their own DNS servers, which can be slow or block requests. Replace them with Google's public DNS servers (8.8.8.8) or Cloudflare (1.1.1.1) often speeds up network response and solves the "Connected, but no internet access" problem.
Impact of power saving and third-party applications
Aggressive battery optimization in shells MIUI And HyperOS It can kill the Wi-Fi connection if the screen is off or the app is running in the background. Check the battery settings for network-related system services.
Go to Settings → Battery → Battery protectionMake sure system processes aren't set to "No Limits" or, conversely, to "Severe Economy" if you notice a pattern in disconnections. Also, check your installed antivirus or VPN applications. They may intercept traffic and block connections due to certificate errors.
If you have an app installed that "speeds up your internet" or "cleans memory," try uninstalling it. These programs often make changes to system files. hosts or network priorities that conflict with the standard operation of Android.
Hardware problems and factory reset
If software solutions have failed, a physical fault with the Wi-Fi module cannot be ruled out. This could be due to a drop, exposure to water, or a manufacturing defect. Symptoms of a hardware problem include a gray Wi-Fi icon that won't turn on, or a complete lack of network listings even after a reset.
The final software step is a full factory reset (Hard Reset). Before doing this, be sure to back up your data to the cloud. Mi Cloud or to a computer, as all information will be deleted.
- 🔒 Go to
Settings → About phone → Factory data reset. - 🔒 Select "Erase all data".
- 🔒 Once turned on, the phone will be like new. If Wi-Fi doesn't work on a clean system, it's 99% likely a hardware issue.
⚠️ Important: Before performing a hard reset, make sure you remember your Google and Mi Account passwords. Without them, you won't be able to activate your phone after the reset due to anti-theft protection.
In the event of a hardware failure, the only solution is to replace the Wi-Fi module at a service center. However, statistics show that most problems are resolved by configuring the router or resetting the network, as described above.
Can an Android update break Wi-Fi?
Yes, sometimes new firmware versions contain bugs that disrupt driver functionality. If the problem appears immediately after an update, you should wait for a patch or, for advanced users, roll back to the previous software version using Mi Flash Tool.
Why does Redmi say "Saved, protected" and won't connect?
This means the phone sees the network and is trying to connect, but the password doesn't work or the encryption type doesn't match. Check if MAC address filtering is enabled in the router, or try changing the router's security type from WPA3 to WPA2/WPA2-Personal.
What should I do if Wi-Fi works, but the internet doesn't load?
The issue is most likely with your DNS or date settings. Also, check if your data plan has run out or if your router is blocking your device with parental controls. Try opening the website in incognito mode.
Does Airplane Mode Help with Wi-Fi Problems?
Yes, turning on airplane mode for 10-15 seconds completely disables all radio modules and restarts them when you turn off the phone. This is a quick way to reset the network stack without rebooting the phone.
Does the case affect Wi-Fi signal reception?
Metallic cases or cases with magnetic closures can block the signal, especially the antennas located at the top of the Redmi device. Remove the case to check the connection quality.
