The situation when smartphone stops detecting wireless networks, often catching you off guard, depriving you of access to important information. Owners of devices of this brand LG This can occur either after a system update or spontaneously. Typically, the problem stems not from a hardware failure, but from a software glitch or a settings conflict.
First, it's important to determine the scale of the problem: is the network down on just one device or has it stopped working on all devices in the house? If router If the error is functioning normally on other devices, then the root cause needs to be addressed within the phone itself. A simple hardware restart, which clears temporary cache errors, often helps.
In this article we will examine in detail all the possible reasons why LG phone The device may be ignoring the WiFi signal. We'll cover everything from simple steps like checking airplane mode to complex IP address manipulation and resetting network settings. Careful adherence to these instructions will allow you to restore your connection without calling a service center.
Basic diagnostics and equipment testing
Before delving into the system's deep settings, it's important to rule out trivial external factors. Users often forget that the wireless module could have been accidentally disabled or blocked by system restrictions. Check if the mode is currently activated. On the plane, which forcibly jams all radio modules.
The second important factor is your physical distance from the access point. If you're too close, your phone may simply not have a strong enough signal to show up in the list of available networks. Try moving closer to the router and refreshing the list of networks by swiping down in the WiFi menu.
It's also worth paying attention to the router's status. If the lights on the provider's device are flashing unusually or are red, the problem may be with the service provider. In this case, even a working router LG smartphone will not be able to find the network because it is not broadcast.
Sometimes switching between frequency bands helps. If your router is dual-band, it can broadcast both 2.4 GHz and 5 GHz networks. Older phone models LG may not support the 5 GHz frequency, so they simply will not see the corresponding network in the list.
Software failures and module reboots
Android operating system installed on devices LG, tends to accumulate software junk during operation. This can lead to the WiFi module driver no longer correctly processing airwave scan requests. The first step in this situation is a full device reboot, not just turning off the screen.
If a regular reboot doesn't help, try a soft reset of the radio interfaces. To do this, turn off WiFi, wait 10 seconds, and then turn it back on. In some cases, sequentially turning the mode on and off may be more effective. On the plane.
- 📱 Log in Settings and find the "Connections" or "Network and Internet" item.
- ✈️ Activate airplane mode, wait 10-15 seconds, then turn it off.
- 🔄 Tap the WiFi icon to force a search for available hotspots.
There is also a hidden testing menu available on many models. LGBy entering the code in the dialer ##4636## (does not work on all firmware), you can get into the testing menu, where the option is available WiFi InfoThere you can try disabling and re-enabling the module at a deeper level.
IP address conflicts and DHCP settings
One of the common reasons why the phone LG If the network is visible but not connected to it (or remains stuck in the "Obtaining IP address" status), there is an address conflict. Two devices on a local network cannot have the same address. IP addressIf the router assigns an address that is already taken by another device, a connection error will occur.
To fix this, you need to change the IP settings from dynamic to static for a specific network. Go to WiFi settings, click on the desired network (or the gear/arrow icon next to it), and find the option IP SettingsBy default it is there DHCP.
Switch the value to Static (Static). You'll need to enter the information manually. Usually, changing the last digit in the IP address field is sufficient (e.g., 192.168.1.5 to 192.168.1.158). The gateway and network prefix usually remain unchanged.
| Parameter | Value for DHCP | Meaning for Static IP |
|---|---|---|
| IP address | Automatically | 192.168.1.X (where X is from 2 to 254) |
| Gateway | Automatically | 192.168.1.1 (usually) |
| Prefix length | Automatically | 24 |
| DNS 1 | Automatically | 8.8.8.8 (Google) |
After saving the settings, the phone will attempt to reconnect using the new address. This often resolves the issue where the device gets stuck at the authorization stage.
Reset network settings to factory defaults
If manipulating IP addresses does not help, the system may have accumulated critical errors in the configuration of network protocols. Function Reset network settings Restores all connection-related settings to their original state. This is a safe operation that does not delete your personal photos or contacts.
To perform this procedure on smartphones LG you need to go to the menu Settings → General → Reset. There select the item Reset network settings (Network settings reset). The system will warn you that saved WiFi passwords, Bluetooth settings, and mobile network settings will be deleted.
☑️ Checklist before resetting the network
After confirming the action, the phone will reboot. You will need to re-enter your home network password. This method is especially effective if the phone stopped detecting WiFi after an unsuccessful firmware update or installing questionable apps.
⚠️ Attention: Resetting network settings will delete all saved WiFi passwords and Bluetooth pairings. Make sure you remember your home network password or have it written down on your router before performing this operation.
Date, time, and security issues
Few people realize it, but an incorrect date and time can block connections to secure networks. Security protocols WPA2/WPA3 use certificates that have an expiration date. If the time on the phone LG is very different from the real one, the security server will reject the connection.
Check the date and time settings in the menu General Settings → Date and TimeMake sure "Auto-detect" or "Use network time" is checked. If automatic detection doesn't work, set the time manually, down to the minute.
It's also worth checking the encryption type on your router. Some older phone models LG do not support new encryption standards such as WPA3If the router is configured only for WPA3, the phone may simply not see the network or return an error when attempting to log in.
How do I change the encryption type on my router?
Access your router settings via a browser (usually 192.168.0.1). Find the Wireless Security section. Change the security mode from WPA3 to WPA2/WPA Mixed or simply WPA2-PSK (AES). Save the settings.
Hardware malfunctions and service maintenance
If none of the software methods helped, and the phone LG If the device still doesn't detect any WiFi networks (even open ones), there's a high probability of hardware failure. This could be a loose antenna cable inside the case or a faulty WiFi module on the board.
Such problems often occur after the device has been dropped or exposed to water. Even if the phone continues to function, a microcrack in the module's solder joint can disrupt contact. In this case, a software reset or reflashing the firmware will no longer help.
- 🔍 The phone sees networks, but the WiFi button is grayed out and inactive.
- 📉 The signal is only received in close proximity to the router (1-2 meters).
- 🔥 The device gets very hot in the camera area when trying to turn on WiFi.
In this situation, diagnostics at a service center are required. Technicians will check the voltage on the module and, if necessary, replace the antenna or reball the chip. Self-repair without experience and soldering equipment can result in complete inoperability of the smartphone.
⚠️ Attention: If your phone is under warranty, do not open the case yourself. Breaking the seals will result in denial of a free repair, even if the phone is defective.
Frequently Asked Questions (FAQ)
Why can my LG phone see my neighbors' WiFi but not my network?
Most likely, your router is operating on a channel or frequency that your phone isn't currently scanning, or the SSID is hidden. Try rebooting the router or changing the broadcast channel in its settings to a more standard one (1, 6, or 11).
Can a virus block WiFi on Android?
Yes, some malware can modify system files responsible for network connections. It is recommended to scan your device with an antivirus program, such as Google Play Protect or a third-party solution.
Will factory reset delete all data?
A hard reset will erase all data. However, the "Reset Network Settings" mentioned above only removes WiFi and Bluetooth passwords, leaving photos and contacts intact.
Does the case affect WiFi signal reception?
Metallic cases or cases with magnetic closures can block the signal. Remove the case and check if the network appears in the list of available networks.
