Many users are familiar with the situation where your smartphone, tablet, or laptop displays an endless loop with the words "Obtaining IP address" or "Registering on network" instead of the familiar Wi-Fi icon. This means that the wireless device has successfully found an access point and exchanged passwords with it (if the network is secure), but is unable to obtain a digital address from the router for full internet access.
At this moment network interface The device is in a suspended state: it appears to be connected, but no data is being transmitted. The problem could be a software glitch on the device itself, an overloaded router, or an IP address conflict within the local network.
Most often, the process gets stuck at the protocol execution stage. DHCP, which is responsible for automatically distributing addresses. If the router doesn't respond to the device's request or its address table is full, you'll see the registration message indefinitely until the system returns a connection error.
Don't panic and take your equipment to a service center right away. In most cases, diagnostics shows that the problem can be solved by simply rebooting the equipment or resetting network settings, which only takes a couple of minutes of your time.
The technical essence of the problem: protocols and addresses
To understand why the error occurs, you need to understand the handshake process between your gadget and the router. When you select a network from the list of available networks, the authentication process begins. If the password is correct, the device sends a broadcast request to receive IP addresses.
A router acting as a DHCP server must allocate a free address from the pool and inform the device of the subnet mask, gateway, and DNS servers. If this dialogue is interrupted or the router ignores the request, the "Registering on Network" status appears. This may occur due to incompatible encryption standards or a router buffer overflow.
⚠️ Note: If the problem occurs only on one specific device, it's most likely due to its network module or saved network profile. If all devices in the house are freezing, the problem lies with the router or ISP.
Sometimes the problem is caused by a static address conflict. If you previously manually assigned an IP address to a device, and now the router is trying to assign the same address to another device, a collision will occur. In this situation network stack will not be able to complete the connection correctly.
Basic steps: reboot and reset
The most effective and universal solution is to perform a full hardware reboot. This clears the router's RAM of temporary errors and resets frozen DHCP processes.
Don't just press the power button. To fully discharge the accumulated electrical charge in the capacitors, unplug the router from the power outlet for 15-20 seconds. Only then plug it back in and wait until it fully boots up and all the indicators light up.
☑️ How to reboot your router correctly
On the client side (smartphone or laptop), it's also helpful to reset network settings. On Android, you can do this through the "Backup and reset" menu and select "Reset network settings." This will delete saved Wi-Fi passwords and Bluetooth settings, but it often resolves the registration freeze issue.
For iPhone owners, a similar operation is located in the section General → Transfer or reset iPhone → Reset → Reset network settingsAfter this procedure, the device will behave as new in terms of wireless connections.
DHCP settings and address pool in the router
If rebooting doesn't help, the problem may be a limited DHCP address pool. By default, many routers allocate a small range of addresses, such as 100 to 150. If you have many guests or smart devices connected to your network, there may simply not be enough available addresses.
To resolve this, you need to log into the router's web interface. This is usually done at 192.168.0.1 or 192.168.1.1. Find the section LAN or DHCP ServerHere we need to expand the range of distributed addresses.
| Parameter | Default value | Recommended value | Description |
|---|---|---|---|
| Start IP | 192.168.1.100 | 192.168.1.2 | Pool starting address |
| End IP | 192.168.1.150 | 192.168.1.254 | Pool end address |
| Lease Time | 120 min | 60 min | Address rental time |
| Max Users | 10 | 32 | Maximum clients |
Reducing the lease time also helps more quickly release addresses no longer in use by disconnected devices. This is especially important for sites with a large number of transient clients.
⚠️ Important: When changing DHCP settings, make sure that your static IP (if used to access the router) is not in the dynamic range to avoid address conflicts.
In some cases, temporarily disabling the DHCP server and manually assigning an IP address to the affected device can help. However, this solution is only suitable for experienced users who understand their subnet structure.
How to manually enter an IP address on Android?
Go to Wi-Fi settings, click on the desired network, and select "Edit." In the advanced settings, change the IP from DHCP to "Static." Enter the IP address (e.g., 192.168.1.155), gateway (192.168.1.1), and DNS (8.8.8.8). Save the settings.
Wi-Fi frequency and channel conflicts
In apartment buildings, the airwaves are often oversaturated with signals from neighboring routers. If your router is operating on a channel that is heavily jammed by neighbors, data packets may be lost, and the registration process will take forever due to timeouts.
It is recommended to switch the router to work in the range 5 GHz, if your devices support it. This band is less crowded and provides a more stable connection. If you're using 2.4 GHz, try changing the channel manually.
Use Wi-Fi analysis apps (eg. WiFi Analyzer) to find the least congested channel. Typically, these are channels 1, 6, or 11, but in densely populated areas, any other channel may be available.
It's also worth checking the security type. Outdated encryption standards, such as WEP or WPA/TKIP, may cause problems with modern devices. Set the mode WPA2-PSK (AES) or WPA3, if the router allows it.
Problems on the operating system side
Sometimes the root of the problem lies in the wireless adapter drivers or OS system bugs. On Windows, it's worth trying resetting the TCP/IP stack via the command line. Launch Terminal as administrator and enter the following command:
netsh int ip resetAfter running the command, be sure to restart your computer. This operation resets TCP/IP protocol settings to factory defaults, removing any invalid registry entries.
On mobile devices, a common cause is the "Randomized MAC Address" feature, implemented in Android 10 and iOS 14 to protect privacy. Some older routers don't work correctly with changing MAC addresses.
Try going to your phone's Wi-Fi settings and finding "Privacy" or "MAC Address Type" and switching it from "Random" to "Device MAC Address." This will force the device to use its permanent physical address, which often resolves the registration issue.
When is it time to update your router firmware?
Router manufacturers regularly release firmware updates that fix DHCP server bugs and improve compatibility with new devices. If none of the above methods help, check for new firmware.
Usually the update section is located in the menu System Tools → Software Update. Modern routers (TP-Link, ASUS, Keenetic) can check for updates automatically via the Internet.
⚠️ Important: Do not interrupt the firmware update process! Do not unplug the router or close the browser until the progress bar reaches 100%. Doing so may damage the device.
If automatic updates don't work, you can download the firmware file from the manufacturer's official website. It's important to download the version that strictly matches your router model (including the hardware revision indicated on the sticker).
After successfully installing the new firmware, it is recommended to reset the router to factory settings (button Reset on the case) and reconfigure the network. This will prevent old configuration files from interfering with the new software version.
Detailed FAQ on connection errors
Why does my laptop connect, but my phone says "Registering on the network"?
Most likely, the phone has MAC address randomization enabled, which the router sees as a new device and is unable to assign it an IP address due to pool overflow or filtering. It's also possible that the phone's time is incorrect, preventing it from passing security certification.
Can antivirus software block Wi-Fi connections?
Yes, some aggressive firewall settings in third-party antiviruses can block DHCP requests. Try temporarily disabling your antivirus's firewall and see if network registration works.
What should I do if the error only appears at a certain time of day?
This is a sign of channel congestion from neighbors or an overheating router. During peak hours (evenings), the airwaves are congested, and the router may not be able to handle the number of connections. Changing the channel, installing a router cooler, or switching to 5 GHz may help.
Does resetting network settings delete my photos and contacts?
No, the "Reset Network Settings" feature only affects connection settings: Wi-Fi passwords, Bluetooth, and mobile network settings. Your personal files, apps, and contacts will remain intact.
The router is new, just from the store, but it's stuck registering. What should I do?
The factory firmware may be buggy. Try updating it via an Ethernet cable, connecting your computer directly to the router. If this doesn't help, the device may be defective—you should contact the store for a replacement.
