The situation when a smartphone stops detecting the home network or endlessly hangs on the “Obtaining IP address” status is familiar to many owners of devices based on the operating system AndroidThis can happen at the most inopportune moment: during an important video call, while loading a work document, or simply when you want to watch a movie. Don't panic, as in most cases the problem stems from a software glitch or incorrect settings, which can be easily fixed without calling a technician.
Before delving into complex technical issues, it's important to perform a basic hardware diagnostic. Often, the problem isn't the phone itself, but the router, which may have frozen after a power surge or been running for a long time without rebooting. It's also worth checking if other devices on your network, such as a laptop or tablet, are working to isolate the problem.
In this article, we'll walk you through the process, from simple steps to advanced settings, to help restore your connection. You'll learn how to properly reset your settings, check for IP address conflicts, and set up a static IP if your router's automatic address assignment fails. Follow the instructions carefully to get your device back online.
Initial diagnostics and basic checks
The very first step when experiencing connection issues is to simply check the physical condition of the devices and their locations. Make sure the router's lights are on. WAN And WLAN (or Wi-Fi), indicating internet access and an active wireless network. If the indicators are blinking abnormally or are not lit at all, the device may need to be rebooted or have a power issue.
On the smartphone side, it's also worth checking a few obvious but critical points. Sometimes the system Android The connection may be blocked due to airplane mode or communication module errors. Try turning the wireless module off and on again through the notification shade to initiate a new search for available access points.
If simple methods don't help, check the date and time on your device. An incorrect system date can cause security certificate errors, causing the router to reject the phone's connection, deeming it unsafe. Set automatic time synchronization via the network or set the correct values manually.
- 📡 Check that Wi-Fi is enabled in your smartphone settings and that Airplane mode is not activated.
- 🔌 Make sure the router is connected to a power source and the indicators are working properly.
- 📅 Check the system time and date on your phone with the current ones.
- 📶 Try moving closer to the router to eliminate the influence of physical obstacles.
Restart and reset network settings on Android
If basic checks fail, you'll need to perform a deeper cleanup of your device's network settings. Operating System Android Over time, errors accumulate in the network service cache, which can interfere with normal connections. A standard phone reboot often helps clear temporary files and restart services, but sometimes a forced reset of network settings is required.
The "Reset Network Settings" feature is safe because it doesn't delete your personal data, photos, or apps. It simply resets all connection-related settings to factory defaults: Wi-Fi, Bluetooth, and mobile data. After this procedure, you'll need to re-enter your home network password, but this often resolves conflicting configurations.
☑️ Network settings reset algorithm
It's important to note that after resetting your phone, all saved Wi-Fi network passwords will be deleted. Therefore, if you don't remember your home network password, it's best to check it with other users or look at the sticker on the router before performing this operation. This will save you time and frustration.
⚠️ Attention: Resetting network settings will also delete paired Bluetooth devices (headphones, watches, and earbuds). You'll need to pair them again.
To perform a reset, go to the menu Settings → System → Reset settings → Reset Wi-Fi, mobile data, and Bluetooth settingsThe path may vary slightly depending on your smartphone model (Samsung, Xiaomi, Huawei), but the essence remains the same. After rebooting, try connecting to the network again.
Forget the network and reconnect
One common reason for connection failure is changing the router's security or channel settings, while the phone continues to use the old, outdated settings. The smartphone "remembers" the previous configuration, causing a conflict when attempting to handshake with the access point. The solution is to delete the network profile from the device's memory.
To "forget" a network, go to the list of available connections, find your home network, and select "Delete" or "Forget." This will clear the saved password and encryption settings for this access point. Your phone will then treat your network as a new, previously unknown one.
When reconnecting, the system will ask for a password. Enter it carefully, paying attention to the case, as Wi-Fi passwords are case-sensitive. If after entering the password, the status changes to "Authentication Error" or "Incorrect Password," try entering it again, ensuring that you haven't mixed up similar characters (for example, zero and the letter O).
Why doesn't the phone see the network after a reset?
In some cases, the router hides the SSID (network name) or operates in compatibility mode, which the old phone doesn't recognize. Try temporarily renaming the network in the router settings so that the phone sees it as a new access point.
If the problem persists even after deleting the profile, it's worth checking the security type. Modern routers often use the standard WPA3, which may not be supported by older phone models. In this case, you can try temporarily switching the security mode to [unsupported] in the router settings (via a computer). WPA2-PSK (AES), which is the most universal.
Using a static IP address
When a phone gets stuck at the "Obtaining IP Address" stage, it often indicates a problem with the router's DHCP server. The server may be unable to assign a new address to the device due to an address pool overflow or a software glitch. In this case, manually assigning a static IP address can be an effective solution, allowing you to bypass the automatic request stage.
To set up a static IP, go to the advanced settings of your Wi-Fi network. This is usually hidden in the "Advanced" menu or accessible by long-pressing on the network in the list of available networks. Find "IP Settings" and toggle it off. DHCP on Static (Static) You will need to enter several numerical values manually.
| Parameter | Meaning (Example) | Description |
|---|---|---|
| IP address | 192.168.1.128 | Unique phone address on the network |
| Gateway | 192.168.1.1 | Your router's address |
| Network prefix length | 24 | Subnet mask (usually 24) |
| DNS 1 | 8.8.8.8 | Google Server (Primary) |
| DNS 2 | 1.1.1.1 | Cloudflare Server (Alternative) |
Please note that the gateway address must match your router's address (often found on a sticker on the bottom of the device). Your phone's IP address should be in the same range, but not the same as the gateway address or other devices. Using public DNS servers, such as 8.8.8.8 from Google, often speeds up network response and solves DNS cache problems.
Problems with the 2.4 GHz and 5 GHz frequency ranges
Modern routers are often dual-band, broadcasting the network simultaneously in frequencies 2.4 GHz And 5 GHzOlder or budget phone models may not support the 5 GHz band, or, conversely, may attempt to connect to it with a weak signal, as this frequency has poorer penetration through walls. If your phone "sees" the network but won't connect, try separating the networks in your router settings.
The 2.4 GHz frequency offers greater range, but is slower and susceptible to interference from microwave ovens and neighboring networks. The 5 GHz band offers high speeds but has a shorter range. If you're far from your router, your phone may not be able to penetrate walls at high frequencies.
In the router settings, you can give different names to networks, for example, HomeWiFi_2G And HomeWiFi_5GThis will force your phone to select the desired network. If your phone is older, select 2.4 GHz. If it's new and you're near a router, select 5 GHz.
⚠️ Attention: Router interfaces are constantly being updated. The exact location of frequency settings may vary. Please check the manual for your router model or the manufacturer's official website.
MAC filtering conflicts and third-party applications
Sometimes the blocking is caused by a router security feature known as MAC filtering. If the network owner has previously configured the router to only work with a specific list of devices, your phone, even with the password, won't be able to access the internet. A MAC address is a unique identifier for a network interface, which can be found in the section About phone → Status.
Installed applications, such as antivirus software or VPN clients, may also be contributing to the problem. They can intercept network traffic and block connections if they detect the network as unsafe or if they malfunction. Try temporarily disabling your VPN and uninstalling third-party antivirus software to check.
In rare cases, resetting the router's date and time settings can help if it's out of sync with global time, which affects security certificate verification. However, this requires access to the router's admin panel via a computer browser.
- 🛡️ Check the MAC filtering list in your router settings and add your phone there.
- 📱 Disable VPN and antivirus applications during diagnostics.
- 🔄 Uninstall recently installed apps that may control your network.
- 🔍 Check if the Parental Control feature with time limits is enabled.
Frequently Asked Questions (FAQ)
Why does my phone say "Saved" but there is no internet?
The "Saved" status means the password was accepted correctly, but data exchange between the phone and router is not established. This could be due to an incorrect date on the phone, problems with the provider's DNS servers, or the router being frozen and not assigning IP addresses. Try setting the static DNS to 8.8.8.8.
Can an Android update break Wi-Fi?
Yes, after a major system update, network drivers sometimes get lost or power-saving settings aggressively disable the Wi-Fi module. In these cases, a full network settings reset or, in extreme cases, a factory reset can help.
What should I do if my phone sees all networks except mine?
Your router may be operating on a channel your phone doesn't support (for example, channels 12-14 in the 2.4 GHz band, which are restricted in some regions). Go to your router settings and change the Wi-Fi channel to automatic or select channels 1 through 11.
How to find out the phone's MAC address for filtering?
Go to Settings → About phone → General information (or Status). The Wi-Fi MAC address will be listed there. Please note that newer versions of Android may use a randomized MAC address for privacy reasons; this should be disabled in the specific network's properties.
