Secrets to fix the IP Configuration failure

Why does your device sometimes refuse to connect to wi-fi, showing an IP configuration failure? This issue may arise from temporary glitches, configuration problems, underlying hardware, or network faults.

If your internet suddenly stops working and you see a message like IP configure failure or cannot obtain IP address your device is struggling to establish a valid address on network.This is not a technical hiccup without a correct IP address your computer,phone,or tablet cannot communicate with other devices or access the internet.

You can fix an IP configuration failure by restarting your device and router, running the Windows network troubleshooter, resetting TCP/IP address, updating or installing network adapter drivers, and checking the router's DHCP settings. 

In this blog, we will help you recognize the major causes of IP configuration failure and the secrets that fix your IP configuration problems.

What is IP Configuration?

It tells your device how to connect to networks and communicate with other devices. It is a process of configuring and managing the Internet Protocol address on the Internet. The main key points are IP address, subnet mask, default gateway, and DNS server.

IP address

An IP address is an Internet Protocol address is a unique number assigned to each device connected to a network.

Subnet mask

The subnet mask defines which part of the IP address refers to the network and which part refers to your device.

Default Gateway

It is the IP address of your router that serves as a path between your local network and the outside world.

Common causes of IP Configuration failures and their solution 

The main causes of not obtaining an IP address are incorrect network issues, router issues, faulty network adapters, software glitches, ISP issues, or IP conflicts.

You can simply fix an IP configuration failure by restarting your device and router, running the Windows network troubleshooter, resetting TCP/IP address, updating or installing network adapter drivers, and checking router DHCP settings. 

1. Incorrect Network settings

 Your device is using the wrong IP or DNS, often due to manual configuration, switching networks, or corrupted settings after a software update.

Solution:

Check the network setting, ensure that your device is set to a DHCP address automatically.

On Windows 10/11

Step 01:Open  network and internet settings, change adapter options

Step 02: Right-click your connection, then click on properties.

Step 03:Select Internet Protocol version 4 (TCP/IPv4). Obtain an IP address automatically.

ON  Android 

You can find your IP address on your phone by clicking on wifi, scrolling down, and you will see the IP address. You can also change the IP address, scroll down, and change the IP setting from DHCP to static apply to save.

Here`s the step for network settings to solve IP configuration problems:

Step 01:Open the settings and click on General management.

Step 02: Next, tap on the reset option.

Step 03: Select reset password, mobile, and Bluetooth. Confirm by tapping the reset setting.

Step 04:Then click on reset settings to confirm it. Restart the phone and reconnect to Wi-Fi.

 2. Router issues 

Sometimes router DHCP servers fail to assign IP addresses due to bugs, outdated firmware, overload, or misconfiguration.

Solution:

• Restart the router or device. 
• Update router firmware from the manufacturer`s website
• Ensure DHCP is enabled in router settings.
• If too many devices are connected, increase the DHCP range or disconnect unused devices.
• Faulty Network adapter 

3. Faulty Network adapter 

The network adapter is the hardware responsible for connecting to the network if it's physically damaged, replace it or if it's damaged or driver software is corrupted, it cannot properly negotiate an IP address.

Solution:

Update or reinstall network adapter drivers.

Step 01:On Windows, open Device Manager 

Step 02: Then click on the network adapter from the options.

Step 03:Right-click on the Problematic device, more options appear.

Step 04:Then click on update driver or uninstall, then restart.

4. ISP problems

ISP (internet service provider), sometimes the problem is not in your device or at the router, it's with the ISP. If their equipment cannot authenticate your connection or they are experiencing an outage, your IP assignment will fail.

Solution :

• Contact your ISP to check for outages
• Restart your modem or router
• It can occur if DHCP assigns the same IP to two devices due to a bug. This confuses the router and prevents proper network communication.
•  Restart both devices. Most routers assign new IPs automatically
• Manually set a different static IP in the network settings.

Obtain a new  IP BY Command Prompt

Enter a new IP address using the command prompt.

Step 01: Press Win+R to open the command prompt.

Step 02:Enter ipconfig/release, then enter the current IP.

Step 03: After it types ipconfig/renew, press enter to obtain a new IP address. Then enter exit to close the window.

Conclusions 

By identifying the root cause, whether it's a DHCP error, outdated drivers, a faulty router, or IP conflict, you can apply targeted fixes to restore your internet connection. Addressing IP configuration promptly through correct settings, driver updates, and network maintenance minimizes downtime and preserves consistent connectivity.
