The situation when Xiaomi The problem of the Wi-Fi indicator not detecting the wireless network or getting stuck on the "Obtaining IP address" stage is familiar to many owners of these smartphones. The problem can manifest suddenly: yesterday everything was working perfectly, but today the Wi-Fi indicator is either gray or completely absent. Users often panic, believing the communication module has burned out, but in 90% of cases, the problem is caused by a software glitch or incorrect router settings.
Before taking your device to a service center, you need to perform a basic check diagnostics software. Errors may be related to a firmware update. MIUI or HyperOS, which changed the WPA3 protocol security standards, or with a DNS server conflict. Sometimes, simply rebooting the router is enough to restore the connection.
In this article, we'll explore all possible causes, from simple system glitches to complex broadcast channel settings. You'll learn how to properly configure a static IP, reset network settings, and check if your router is blocking your device by MAC address. Follow the instructions carefully to restore your smartphone's internet access.
Basic diagnostics and module reboot
The first step should always be a simple reboot. This isn't a cliché, but a real way to clear the cache of network services that may be stuck in the background. Xiaomi If your Wi-Fi connection isn't detected, try turning your phone off completely and turning it back on after 10-15 seconds. This will force a restart of the wireless module drivers.
If a simple reboot doesn't help, it's worth checking the router itself. Often, the problem isn't with your phone, but with overheating or a frozen router. Try connecting to the same network from another device—a laptop or tablet. If other devices also can't see the network, the problem is definitely with your ISP or hardware.
⚠️ Note: If your router operates in dual-band mode (2.4 GHz and 5 GHz) and uses the same network name (SSID) for both bands, older Xiaomi models may lose connection. Try temporarily separating the network names in your router settings.
There's also a hidden feature in Android that allows you to reset network settings without deleting your personal data. This will reset all Bluetooth and mobile settings to factory defaults. Go to Settings → Connection and sharing → Reset Wi-Fi, mobile networks, and BluetoothAfter this procedure, the phone will behave like new in terms of connections.
Setting up static IP and DNS
One of the most common reasons why a phone sees the network but doesn't connect to the internet is an IP address conflict. A router can assign the same addresses to different devices, causing Xiaomi It kicks you out of the network. The solution is to manually assign a static IP address.
To do this, click the gear icon or arrow next to your network name in the list of available connections. Find "IP Settings" and switch it from "DHCP" to "Static." You'll need to enter the address manually, which is usually 192.168.1.128 or 192.168.0.128, depending on your router's gateway.
Pay special attention to the DNS fields. ISPs often block access or process requests slowly. Replacing the default DNS with public servers from Google or Cloudflare can work wonders. In the DNS 1 field, enter 8.8.8.8, and in the DNS 2 field - 8.8.4.4This will speed up the response of the domain system.
☑️ Checking static settings
It's important to understand that if you change your router or move to a new office, you'll have to reset these settings again, as the address range will be different. If you're unsure of the numbers, it's best to leave DHCP mode enabled, but make sure there are no duplicates in the router's list of connected clients.
Problems with the broadcast frequency and channel
Modern smartphones Xiaomi 5 GHz networks work great, but in apartment buildings, this range is often overcrowded. If your phone constantly loses signal or can't detect the network at all, it's possible it's on a crowded channel. Routers often default to "Auto," which isn't always effective.
Access your router settings (usually through a browser at 192.168.1.1) and find the Wireless Settings section. Try manually changing the 2.4 GHz channel to 1, 6, or 11. For the 5 GHz band, it's best to choose channels in the 36-48 range or above 149 if they're clear of neighboring networks.
| Parameter | Recommended value | Description |
|---|---|---|
| 2.4 GHz channel | 1, 6, 11 | The only non-intersecting channels |
| Channel width | 20 MHz | For stability in noisy airwaves |
| Standard | 802.11 n/g mixed | Maximum compatibility |
| Region | Russia / Europe | Compliance with legislation |
It's also worth paying attention to the channel width. In densely populated areas, the width setting 40 MHz or 80 MHz may lead to unstable operation. Reducing the width to 20 MHz will reduce the speed, but will significantly increase the stability of the connection and the signal range.
Why is 5 GHz reception worse?
The 5 GHz band has less penetration through walls than 2.4 GHz. If there are many walls between the router and the phone, the phone may simply not see the high-frequency network.
Date, time, and regional settings are incorrect.
It might seem like time has nothing to do with Wi-Fi. However, security protocols like WPA2 and WPA3 rely on certificates that expire. If your Xiaomi If the date is incorrect (for example, it is set to 2015), the security system will consider the connection unsafe and block access.
Check the settings in the menu Settings → Additional settings → Date and timeMake sure "Use network time" is enabled. If automatic setting doesn't work, manually set the current date and time. This often resolves the "Authentication Error" error on your phone.
Another nuance is the device's region. Some Xiaomi models intended for the Chinese market (CN Version) may have restrictions on the use of certain Wi-Fi channels that are permitted in China but prohibited in Europe or the US. Changing the region in the phone settings (Settings → Additional settings → Region) to "Russia" or "Germany" can unlock hidden frequencies.
⚠️ Note: The MIUI and HyperOS interface may differ depending on the Android version. If you don't find the "Date & Time" option in the specified path, search for "Time" in Settings.
MAC address conflict and router filtering
Modern versions of Android implement MAC address randomization to protect privacy. Each time a phone connects, it presents itself to the router under a new "name" (MAC address). If the router has whitelist filtering configured, the new address will be blocked.
To fix this, you need to fix the MAC address. Go to Wi-Fi settings, select your network (or click "Add new" if it's not connecting), and find "Privacy" or "MAC Address." Change the setting from "Random MAC" to "Device MAC Address."
After this, copy the displayed address and add it to your router's security settings if filtering is enabled. It's also worth checking that the "Guest Network" mode you're trying to connect to isn't enabled by default with restricted access.
Wi-Fi module hardware failure
If all software methods have been exhausted, and Xiaomi If the network still doesn't see any networks (the list is empty or the wheel is spinning), there's a high probability of hardware failure. Most often, the Wi-Fi/Bluetooth module itself fails due to overheating, impact, or a soldering defect.
Symptoms of hardware failure:
- 📱 Gray Wi-Fi icon that won't activate.
- 📡 The phone only sees 1-2 networks out of dozens of neighboring ones.
- 🔌 At the same time, Bluetooth stopped working (since the modules are often combined).
- 📉 The upper part of the smartphone gets very hot when trying to turn it on.
In such cases, the only solution is resoldering the module or replacing the motherboard at a service center. Self-repair without specialized equipment (soldering station, hair dryer, microscope) is impossible and can lead to permanent failure of the device.
Why doesn't Xiaomi detect 5 GHz Wi-Fi?
Not all Xiaomi models support the 5 GHz band. Budget Redmi series and some Mi models may only have a 2.4 GHz module. Furthermore, if the router is configured for DFS (radar) channels, the phone may not see the network until the router scans the air for radars.
How to reset network settings without losing photos?
Reset network settings (Settings → Connection & Sharing → Reset Wi-Fi...) only deletes saved Wi-Fi passwords, Bluetooth, and mobile network settings. Your photos, contacts, and apps will remain intact.
Can a case block the signal?
Yes, if your case has a metal base, magnetic closure, or thick metal walls, it may shield the antenna. Try removing the case and checking the signal strength.
