You might have seen that ethernet doesn’t have a valid IP configuration on your computer. It shows when your system doesn’t get a valid IP address from the router. And, actually, it comes from your DHCP server). It can be the modem, the switch, or the wireless router.
When you connect your system with a network connection, it will obtain details of the subnet mask, default gateway, IP address, DNS server, and more automatically. It is necessary to process your request for a webpage. However, all the requirements can’t be obtained for some reason, which causes problems because the ethernet does not have a valid IP configuration.
That is why you have to deal with some annoying errors. Sometimes, it can be a limited connection, no internet access, etc. This type of error is not permanent and can be easy to resolve. It comes from software, and you can get rid of them easily.
With that in mind, we are here to help you. Let us tell you which solutions do you need for the ethernet ip configuration error on your Windows PC.
Causes of Errors
Before starting the Ethernet, doesn’t have a valid IP configuration cause you should know about IP. Internet Protocol address offers you to communicate with the internet. Using an IP address, you can communicate with the Internet and access what you want.
However, there are many IP addresses such as public, private, statics, and dynamic. Moreover, there are two types of IP addresses as IPv4 and IPv6. All addresses come in this range.
However, you might face the error message “Ethernet does not have a valid IP configuration”. It means that the Ethernet connection is no longer for IP configuration and Windows OS is down. It receives the IP address from the DHCP.
This network protocol system is responsible for enabling a server to auto-assign an IP address. It uniquely assigns an IP address to your PC for a specific network. Doing so, if you are using a computer and facing an Ethernet problem, then you are not able to connect to a network.
There are lots of reasons behind this, such as faulty, outdated, incorrect network adapter drivers, and more. You can fix them by applying the methods we are going to discuss. Also, you can reinstall the driver, or update network drivers. You have to configure your network settings and try other fixes.
How to Fix Ethernet Doesn’t Have a Valid IP Configuration
Since we have told you that there are lots of reasons behind this problem. These can be
- DHCP issues
- Incorrect configuration in the Network Adapter
- Faulty network driver
- Expired cached files
- Cable Issues
No matter what type of issue you are facing, here we have solutions for all. However, before proceeding, we recommend you restart your Windows PC. Sometimes, rebooting can help you to eliminate most of the issues. After that, you need to follow these steps:
– Reset TCP/IP Settings and Winsock Protocol
The first thing that you need to do is to Reset TCP/IP Settings and Winsock Protocol. This process helps most Windows errors to get rid of the Internet connection, DNS, or IP. So you have to press WINDOWS+X and then select the Command Prompt option from the pop-up menu.
After that, you have to perform this command to reset the Winsock protocol on your Windows computer. When reset has been done, you have to execute these commands to reset the TCP/IP settings:
- netshinttcp reset
- netshintip reset
When you have done it, reboot your system, and that’s all.
Still, if you are facing any issues, then you can follow the following method.
– Clear all the Cached Files
Sometimes cache files take storage and cause invalid IP configuration. If the issue does not resolve, then you have to clean up all the network cached files on your PC. For this purpose, you need to follow these steps. You have to open the command prompt to process the following commands.
- Ipconfig /release
- ipconfig /flushdns
- ipconfig /renew
When you have done these commands, then restart your system. Then you have to connect to the internet or check if your device is working or not. If it is not working, then you have to follow the following step.
– Manually Configure TCP/IP Settings
After completing the above two steps, you need to follow this step to resolve Ethernet’s no valid IP configuration. To do so, you need to follow these steps:
- First of all, you have to right-click on the Network Connection Icon on your taskbar.
- Then you need to select the Open Network and Sharing Center option.
- After that, you have to click on the Ethernet network adapter and click on the properties.
- Then you have to select the TCP/IPv4 then double click on the Internet Protocol Version 4.
- However, if you are using IPv6, then click on it.
Now you have two cases such as:
First of all, you have to configure the Ip address and some other details. It enables you to access the Internet, but it doesn’t or shows the Ethernet valid IP configuration message. You have to switch back to the automatic configuration method. Regarding that, you have
- Select obtain an IP address automatically.
- Then select the DNS server address automatically.
Then you can choose the second case that needs to configure those settings with the static details. It brings a subnet mask, LAN IP address, default gateway, and DNS server. For instance:
- IP address: 192.168.1.112
- Subnet mask: 255.255.255.0
- Default gateway: 192.168.1.1
- DNS server: 184.108.40.206 and 220.127.116.11
After that, you have to remember that your IP and gateway are set to default.
IP Address: You can set any IP address but if you are using the default address, then make sure your IP must be 192.168.11.xxx. But you have to make sure that the IP address that other devices have used will lead to an IP conflict issue.
Default Gateway: It is the IP address of your modem. It depends on the DHCP server.
Lastly, you have to fill in all the needed details, and then you have to click OK. Then you have to reboot your system. Hopefully, the issue will be resolved. If you don’t, you have to follow the next step.
