“Ethernet does not have a valid IP configuration” — have you seen this error? It’s a common issue that many users experience, preventing them from accessing the web. But what is an IP configuration? And how can you fix it?

The “Ethernet does not have a valid IP configuration” error means that Windows can’t receive the IP address from DHCP (Dynamic Host Configuration Protocol), which automatically assigns IP addresses to devices connected to the network.
Your computer needs an IP address to connect to the internet and communicate with the outside world. It’s similar to your home address. If a postman doesn’t know where you live, he can’t deliver your mail; likewise, without a valid IP configuration, the internet can’t send you data.
There could be several reasons for this error: incorrect network configurations, outdated drivers, and more. However, this is not a serious issue and can be solved with even a limited technical knowledge. Just follow these steps to get back online.
Turning your router on and off can work miracles. While this might seem a trivial solution, restarting your router usually solves nine out of 10 internet connectivity issues. When you turn off your router, make sure to count until 10 before turning it on. Additionally, you can also restart your PC.
If the problem persists, you can reset the network adapter and refresh your IP configuration:
Your device obtains an IP address automatically, but it’s worth checking if your settings are correct:
You can also change your default settings manually and see if it helps to connect to the internet:
IP address: 192.168.1.15
Subnet mask: 255.255.255.0
Default gateway: 192.168.1.1
Preferred DNS server: 220.127.116.11*
Alternate DNS server: 18.104.22.168 address.
*In this example, I’m using Google’s DNS server
This will clear your DNS cache on Windows, release your IP address, and renew it.
Windows can identify connectivity issues and fix all kinds of problems. It doesn't always help, but it’s not a bad idea to try:
If you have tried all the options mentioned above and you still bump into the “Ethernet does not have a valid IP configuration” error, contact your internet service provider (ISP) directly for technical support.
Your IP address links your online activities with your identity and location. The websites you visit, the services you use, your location history, search queries, and other sensitive information is all accessible to your ISP and other third parties.
