Many users are familiar with the situation where a phone endlessly displays the "Logging on" or "Obtaining IP address" status when connecting to Wi-Fi. The smartphone screen may turn off and then back on, but the desired connection never establishes, leaving the device without internet access. This is annoying, especially when you need to urgently resolve a work issue or finish an important conversation.
This behavior indicates that the handshake between your device and the router was not successful. The DHCP protocol, which is responsible for automatically assigning addresses, may be blocked by software glitches or hardware conflicts. As a result, the phone gets stuck in a loop of authentication attempts, receiving no response from the router.
In most cases, the problem isn't a faulty smartphone itself, but rather a buildup of software junk or incorrect router security settings. Understanding the nature of this error will help avoid unnecessary trips to the service center. We'll examine the main causes of this error and offer step-by-step solutions.
DHCP server failures and IP address conflicts
One of the most common reasons for freezing at the “Logging on to the network” stage is incorrect operation DHCP servers On the router side. This component is responsible for assigning a unique IP address to each connected device. If the address pool is exhausted or the server freezes, your phone will wait indefinitely for its network connection.
There are also often situations when a problem occurs in the local network IP address conflictThis occurs when two devices are manually or automatically assigned the same identifier. In this case, the router cannot route data packets correctly, and the connection is lost during the handshake process.
Sometimes the static IP address specified in the phone's settings may not match the router's subnet. For example, if the router assigns addresses in the 192.168.1.x range, but the smartphone's address is hardcoded to 192.168.0.5, the connection will fail. In such cases, the system will attempt to find a gateway that doesn't physically exist in the current configuration.
⚠️ Note: If you use a static IP address, make sure it is not in the router's reserved range, otherwise it will conflict with other smart home devices.
Rebooting the router to reset the address lease table is often enough to resolve the issue. If this doesn't help, it's worth checking the DHCP settings in the router's web interface. Make sure the address range is wide enough for all your devices.
Problems with saved network profile and cache
Smartphones save profiles of previously connected networks for quick login in the future. However, over time, this data can become corrupted or outdated, especially if the router's password or encryption type has changed. The phone tries to use the old ones. encryption keys, the router rejects them, but the connection is not broken - the process enters a cycle.
Accumulated caches of operating system network services can also cause crashes. Temporary files responsible for network priority and connection history sometimes contain errors. This is especially true for devices Android, where the depth of integration of system processes is high.
The best solution in this case is the "Forget Network" procedure. This completely deletes the saved profile, including all its parameters and errors. Afterwards, the connection is clear, just like the first time, eliminating the use of incorrect data.
- 📱 Go to your Wi-Fi settings and find the problematic network.
- 🗑️ Click "Forget this network" or "Delete".
- 🔄 Restart your phone to clear network services.
- 🔑 Re-enter your password and try connecting.
☑️ Checklist before resetting network settings
If deleting the profile doesn't help, the problem may be deeper and affect the OS system files. In this case, you may need to reset all network settings to factory defaults. This will affect not only Wi-Fi but also Bluetooth and mobile data settings.
Incompatibility of security and encryption standards
Modern routers support various security protocols, such as WPA2, WPA3, and the outdated WEP. If your router is running a new standard, WPA3If your phone is quite old, it may simply not understand this encryption protocol. As a result, the device will see the network but get stuck at the login stage.
The opposite situation is also possible: new smartphones iPhone or Samsung They may refuse to connect to networks using legacy TKIP encryption, requiring the more secure AES. The router may switch between modes in an attempt to ensure compatibility, which disrupts the authorization process.
A common cause is the "Secure Connection" or "Private Wi-Fi Address" feature built into iOS and Android. It generates a random MAC address for each connection. Some routers with strict security filters block such "changing" devices, preventing them from connecting to the network.
| Security protocol | Compatibility | Recommendation |
|---|---|---|
| WEP | Outdated, unsafe | Do not use |
| WPA/WPA2 Mixed | High | Optimal for older devices |
| WPA2 (AES) | Standard | Recommended option |
| WPA3 | New devices only | For maximum protection |
Check your router's wireless settings. If it's set to "802.11ax Only" or "5 GHz Only," and your phone only supports 2.4 GHz or older standards, n/b/g, there will be no connection. Switch the mode to Mixed for maximum compatibility.
What is MAC filtering?
This is a router security setting that allows network access only to devices with specific physical addresses. If your phone has changed its MAC address (via randomization) or its address isn't whitelisted, the router will allow it to continue logging in indefinitely but won't allow internet access.
The Impact of System Updates and Firmware Bugs
The release of new versions of operating systems often brings not only new features, but also software bugs. After updating iOS or Android Users often notice issues with Wi-Fi stability. Developers may change the algorithms of network modules, which conflicts with the firmware of certain router models.
Sometimes the problem lies in the router firmware itself. If the router hasn't been updated in a while, its software may not correctly process requests from new smartphone versions. This is especially common with budget models, whose manufacturers rarely release security patches.
In rare cases, the failure is caused by third-party applications accessing the network. Antivirus programs, VPN services, or data-saving programs can intercept the connection and block it, creating the illusion of a permanent connection. Disabling such applications helps diagnose the problem.
If the problem appeared immediately after updating your phone, it's worth waiting for a patch from the manufacturer. However, if you don't have time to wait, you can try resetting your network settings. This will return the network modules to their original state, eliminating the effects of the failed update.
⚠️ Note: Settings interfaces and menu item names may vary depending on your OS version and phone model. If you don't find an exact match, look for sections labeled "Network," "Connections," or "Wi-Fi."
Diagnosing hardware problems and interference
Physical causes also cannot be ruled out. If the phone's Wi-Fi module is damaged (for example, after a fall or exposure to water), it may become unstable. In this case, the device will detect networks, but the signal strength or antenna functionality will not be sufficient to complete a handshake with the router.
Strong electromagnetic interference can also disrupt connections during the initial setup phase. Microwave ovens, wireless baby monitors, and even densely populated areas can create noise in the 2.4 GHz band. While the phone will try to penetrate the noise, data packets will be lost.
You can check the module's integrity by connecting to another Wi-Fi network (for example, by sharing internet from another phone). If the same problem occurs there, the issue is most likely with your smartphone's hardware. If everything works at home but not when you're away, the issue is with compatibility with other routers.
- 📶 Check the signal level in different parts of the apartment.
- 📵 Turn off Bluetooth as it operates in the same frequency range.
- 🔌 Try unplugging your router for 10-15 minutes.
- 📱 Check Wi-Fi on other devices in your home.
Drastic measures: Reset network settings
If none of the above methods help, the last software option is a full network settings reset. This operation deletes all saved Wi-Fi passwords, Bluetooth pairings, and mobile network settings. This is guaranteed to eliminate any software configuration conflicts.
You can perform a reset through your phone's settings menu. On Android, the path usually looks like this: Settings → System → Reset settings → Reset Wi-Fi, mobile networks, and BluetoothOn iPhone: Settings → General → Transfer or reset iPhone → Reset → Reset Network Settings.
After this procedure, the phone will reboot. You'll have to re-enter the passwords for all your Wi-Fi networks. However, in 90% of cases, this completely resolves the endless "Logging in to network" issue.
Frequently Asked Questions (FAQ)
Why does Wi-Fi connect, but it says "No Internet access"?
This means there's a connection to the router, but the router itself doesn't have access to the external network. Check your provider's cable, the service status in your account, or your balance. The issue could also be incorrectly set DNS addresses.
Can an antivirus block access to a Wi-Fi network?
Yes, some Wi-Fi Protection features or antivirus firewalls can block connections if they deem the network unsafe. Try temporarily disabling protection and testing the connection.
What should I do if my phone sees the network, but doesn't respond to the "Connect" button at all?
Most likely, the network module is frozen. Restarting the phone may help. If that doesn't help, turn Airplane Mode on and off to restart the radio modules.
Does date and time affect Wi-Fi connection?
Yes, if the phone's time is significantly different from the actual time, security certificate errors may occur, and the router will disconnect. Set automatic time synchronization.
