This can happen due to various reasons, such as network connectivity issues, misconfigured network settings, DHCP server problems, or IP address conflicts<\/a>.<\/p>\n\n\n\n When your IP configuration is wrong, your device may not be able to connect to the network or access the internet.<\/p>\n\n\n\n Keep reading, all the troubleshooting steps are listed below.<\/p>\n\n\n\n Your device may encounter this issue due to several issues. The causes of the issue are listed here.<\/p>\n\n\n\n Network connectivity issues<\/strong>: Connection problems, such as loose cables or damaged ports, can prevent the device from communicating with the network.<\/p>\n\n\n\n Network adapter issues<\/strong>: The damaged driver on your devices or hardware malfunctions can also lead to IP setup failure.<\/p>\n\n\n\n Misconfigured settings<\/strong>: Incorrect IP address settings, such as entering the wrong IP address, subnet mask, or default gateway, can cause the device to be unable to connect to the network<\/a>. What\u2019s more, subnet mask and default gateway errors can result in communication issues between devices on the same network.<\/p>\n\n\n\n DHCP server problems<\/strong>: DHCP server outages or network disruptions can prevent the device from obtaining a valid IP address. If the device fails to renew its IP address lease from the DHCP server, it may result in the DHCP lease expiring, which in turn prevents your DHCP server from obtaining an IP address.<\/p>\n\n\n\n IP address conflict<\/strong>: If another device on the network is assigned the same IP address as your device, it can cause network communication issues.<\/p>\n\n\n\n Firewall or security software<\/strong>: In some cases, firewall or security software settings may block the device from obtaining an IP address from the DHCP server, causing the device to get the wrong IP address.<\/p>\n\n\n\n Sometimes, simply restarting the device can resolve the IP setup failure by resetting network settings and clearing any temporary glitches.<\/p>\n\n\n\n Restart your Android.<\/strong><\/p>\n\n\n\n Restart your router.<\/strong><\/p>\n\n\n\n You may need to check all network cables to make sure they are securely plugged in and not damaged, because any loose connections or faulty ports may cause network connectivity issues.<\/p>\n\n\n\n You can download and use a VPN to resolve the IP configuration failure because it offers you various IP addresses. You can use LightningX VPN<\/strong><\/a> because it allows you to enable IPv6. Here’s how to use LightningX VPN to enable IPv6<\/a>.<\/p>\n\n\n\n Reconnecting to a network can help your device get the correct IP address. However, this method only solves the temporary issue. Check the steps below.<\/p>\n\n\n\n Manually assigning a static IP address<\/a> to your device might help you solve the \u201cIP configuration failure\u201d issue. However, this is a temporary method. Check the detailed steps below.<\/p>\n\n\n\n Turning your Airplane mode on and off can restart your phone settings. This might help your device get the proper IP configuration.<\/p>\n\n\n\n MAC address filtering is a security access control method in computer networking that uses the MAC address assigned to each network interface controller to regulate network access.<\/p>\n\n\n\n For example, if you\u2019re trying to connect your phone to the computer that has a MAC filter through the port, the MAC filter might prevent your device from connecting to it and may cause the no valid IP configuration issue.<\/p>\n\n\n\n If you own the network and router, you can connect to the router and turn off the MAC filter for your Android.<\/p>\n\n\n\n Sometimes your router\u2019s built-in firewall may be changed or enabled by someone. This will cause your IP configuration to be wrong. You can check if your router\u2019s built-in firewall runs well. Here are the detailed steps.<\/p>\n\n\n\n Step 1. Open a browser window.<\/p>\n\n\n\n Step 2. Log in to the router\u2019s administrative console, which needs your router\u2019s IP address (The IP addresses of different routers are listed below).<\/p>\n\n\n\n Step 3. Check if \u201cSecurity\u201d or \u201cFirewall\u201d exists on the IP configuration page. If they exist, it indicates that your router\u2019s built-in firewall is turned on, and it doesn\u2019t affect your IP configuration.<\/p>\n\n\n\n Related: How to Find IP Address on Windows 10\/11, Mac, iPhone, Android.<\/a><\/p>\n\n\n\n If all the methods can\u2019t solve your problem, you can try to reset your device. Resetting your factory data will delete all the data on your phone and bring the phone back to its factory state. You must back up all the important data before resetting it.<\/p>\n\n\n\n![\"DHCP](\"https:\/\/lightningxvpn.com\/blog\/wp-content\/uploads\/2024\/08\/fix-ip-configuration-failure-1-724x1024.png\")
