Many wireless network users are familiar with the situation when a smartphone, tablet, or laptop persistently reports the "Obtaining IP Address" status and then drops the connection. This message means that your device has successfully authenticated with a password, but is unable to obtain a digital ID for data exchange within the local network. Without this IP addresses The router simply doesn't know where to send information packets from the Internet, and the connection freezes at the parameter configuration stage.
Most often, the problem lies not in a hardware failure of the gadget, but in a software conflict or an overflow of the address pool on the router. Android And Windows DHCP server timeouts may react differently, but the essence remains the same: there's a request, but no response. In some cases, a simple reboot is sufficient, but sometimes deeper configuration of network protocols or intervention in security settings is required.
In this article, we'll explore all possible causes of this error, from simple steps anyone can take to advanced methods for setting up static addresses. You'll learn how to diagnose your router's status, clear the network service cache, and set up a static IP address to ensure a stable connection even in busy networks.
Why does the device get stuck at the IP acquisition stage?
Protocol DHCP (Dynamic Host Configuration Protocol) is responsible for automatically assigning IP addresses. When you press the connect button, your device broadcasts a request. The router should respond with an address offer. If this doesn't happen, a retry cycle begins, which the user sees as an endless "Obtaining IP Address" message.
One common cause is exhaustion of the router's address pool. The standard range is typically 100 to 199 addresses. If you have many devices connected to your network simultaneously (smartphones, smart lamps, TVs, guest laptops), there may simply be no available addresses. In this case, a new device has no address to allocate and is left behind.
The problem may also stem from an IP address conflict, when two devices on the network are assigned the same identifier. This often occurs if one device was previously connected with a static address, which is now assigned automatically to the other device. The network security system blocks the connection to prevent data loss.
⚠️ Attention: If the problem occurs only on one specific device, while the others work fine, the problem is most likely with the Wi-Fi module settings of the device itself or its drivers, and not with the router.
Software glitches in the router firmware shouldn't be ruled out either. The DHCP server could freeze or malfunction due to code errors or overheating. In such cases, even the availability of available addresses doesn't guarantee a successful connection, as the allocation mechanism itself stops functioning.
Basic steps: reboot and forgotten networks
The first thing you should do when an error occurs is perform a full reboot of the router. This isn't just a formality; it clears the router's RAM and resets any frozen DHCP server processes. Unplug the router for 10-15 seconds, then plug it back in and wait for it to fully boot up (usually 1-2 minutes).
At the same time, you should perform the "Forget Network" procedure on the affected device. This action deletes the saved connection profile, including any potentially incorrect IP and DNS settings that may have been cached. After this, the phone or laptop will attempt to connect from a clean slate.
☑️ Basic connection diagnostics
If after these steps the "Obtaining IP Address" status changes to "Connected," the issue was temporary. If the problem persists, you'll need to proceed to more detailed settings, such as changing the IP address type from dynamic to static.
Setting up a static IP address on Android
The most effective solution for Android-devices is to manually enter network parameters. This bypasses the step of requesting an address from a DHCP server, which may not respond. You will need to know your current network parameters to enter them manually.
Go to your Wi-Fi settings, click on your network name (or the gear icon) and select "Edit" or "Advanced." Find "IP Settings" and toggle it off. DHCP on StaticThe system will prompt you to fill in the following fields: IP address, Gateway, Network prefix length, and DNS.
In the IP address field, enter a value that differs from your router's address only by the last digit. For example, if your router's address is 192.168.0.1, you could assign 192.168.0.125 to your device. It's important to select numbers between 2 and 254, avoiding those already occupied by other active devices.
Which DNS is best to use?
For static configuration, it's recommended to specify reliable public DNS servers, such as Google (8.8.8.8 and 8.8.4.4) or Cloudflare (1.1.1.1). This often speeds up network response times and resolves page loading issues, even if the connection is technically established.
After saving the settings, the device will attempt to connect using the specified parameters. If everything is entered correctly, the status will immediately change to "Connected." This method is especially useful for older routers that struggle with dynamic address assignment.
Troubleshooting on Windows laptops and PCs
In the operating system Windows The procedure is similar, but has its own interface peculiarities. If the laptop displays "Obtaining IP address" and won't connect, resetting the network settings via the command line or changing the adapter settings often helps.
Open Settings → Network & Internet → Change adapter settings. Right-click your wireless connection and select Properties. Find Internet Protocol Version 4 (TCP/IPv4) in the list, select it, and click Properties.
By default, it's set to "Obtain Automatically." Try switching to "Use the following IP address." Enter your gateway (router) address and assign any available IP address to your computer. You can also try the reset command in the command prompt running as administrator.
ipconfig /releaseipconfig /renew
ipconfig /flushdns
These commands forcibly release the current address (even if it's invalid) and request a new one from the server, as well as flush the DNS cache. In most cases, this resolves the issue of freezing during the network identification phase.
Router Settings: DHCP and Address Pool
If the problem occurs on all devices or a large number of them, you need to change the settings directly on the router. Go to the web interface (usually at 192.168.0.1 or 192.168.1.1) and find the section LAN or DHCP Server.
Check the address pool size. If the range is set, for example, from 192.168.0.100 to 192.168.0.110, only 10 devices can operate simultaneously. Extend the range to 192.168.0.200 to increase the number of available slots.
| Parameter | Recommended value | Description |
|---|---|---|
| Start IP Address | 192.168.0.2 | Start of the issuance range |
| End IP Address | 192.168.0.254 | End of range (maximum) |
| Lease Time | 120 minutes | Address rental time |
| DNS Server | 8.8.8.8 | Primary DNS |
Also pay attention to the "Lease Time" parameter. If it's set too high (e.g., a week), the router will consider the address occupied even after the device is powered off. Reducing this time to 1-2 hours will allow addresses to be released more quickly for new connections.
⚠️ Attention: Interfaces of routers from different manufacturers (TP-Link, Asus, Keenetic) may vary. Look for sections with the words LAN, DHCP, or Network Settings.
Reset network settings and update drivers
When software glitches accumulate, a complete reset of the network settings on the device helps. Android This can be done through the "Backup & reset" menu → "Reset network settings." Please note: this will delete all saved Wi-Fi passwords and Bluetooth settings, but will not affect your personal files and photos.
On computers running Windows A similar function is located in the network settings. It's also critical to keep your wireless adapter drivers up-to-date. An outdated driver may not process DHCP packets correctly, especially on newer routers with the following standards: Wi-Fi 6.
Go to "Device Manager," find your network adapter, and select "Update Driver." If the automatic search doesn't produce a result, download the latest version from the official website of your laptop or motherboard manufacturer.
Additional factors: MAC filtering and power saving
Sometimes the connection is blocked by security settings. Check if your router has filtering enabled. MAC addressesIf your device isn't whitelisted, the router will accept the connection request but won't issue an IP address, formally rejecting the device.
Another hidden enemy is Wi-Fi power-saving mode. On many smartphones, the system limits the communication module's performance when the battery is low. Try disabling power-saving mode and reconnecting to the network. You can also disable the "Randomize MAC Address" option in the advanced Wi-Fi settings on Android and choose to use the device's MAC address, as some routers don't handle randomization correctly.
Why does changing the Wi-Fi channel help?
Airwave congestion from neighboring routers can cause DHCP packet loss. Changing the channel in your router settings to a less congested one (e.g., 1, 6, or 11 for 2.4 GHz) can improve connection stability and server response speed.
Can antivirus block IP address acquisition?
Yes, some aggressive firewall settings in antivirus software can flag DHCP requests as suspicious activity. Try temporarily disabling the firewall to test.
What to do if nothing helps?
If neither a static IP, nor a reset, nor a router firmware update helps, there may be a hardware failure in the Wi-Fi module in the device or a critical firmware error in the router, requiring hardware replacement.
Does password length affect IP address acquisition?
The password itself does not affect DHCP, but complex characters (special characters) in some older routers can cause encoding errors when transmitting the hash, which leads to a break in the authorization stage, which the user perceives as an IP problem.
