Hello guys, this article will explain to you about an error message of Ethernet doesn’t have a valid IP configuration which specifies that your computer Ethernet connection has no valid IP configuration.
This means the operating system is not able to receive an IP address from the DHCP (dynamic host configuration protocol) server.
The DHCP server is a network protocol that assigns an IP address to your computer for a specific network.
If it fails to assign an IP address you will get the error message of Ethernet invalid IP configuration with a yellow triangle ⚠️mark on your network icon.
Note:- Discord no route error can also be because of local area connection doesn’t have a valid ip configuration
What can cause Ethernet doesn’t have a valid IP Configuration
- An issue with Network Interface Card (NIC)
