Ethernet doesn't have a valid IP configuration (Solved)
The error "Ethernet doesn’t have a valid IP configuration" is a common issue faced by Windows users and occurs when the computer fails to obtain a valid IP Address from the router.
An IP address is a unique identifier number that is assigned to every device connected to a network, including computers and smartphones. Without a valid IP address, the device cannot communicate with other devices on the network and, therefore, cannot access the internet.
The mentioned error can appear on both Wireless (Wi-Fi) adapter and Ethernet (LAN) adapter and can be caused by various factors such as corrupted network adapter driver, incorrect network adapter settings, router problem or temporary network outage. Regardless of the cause, resolving the error is critical to getting the network back up and running.
This guide contains fourteen (14) different methods to help you fix the problems:
- Wi-Fi doesn’t have a valid IP configuration
- Ethernet Fi doesn’t have a valid IP configuration
How to FIX: Ethernet or Wi-Fi doesn’t have a valid IP configuration on Windows 10/11.
Suggestion: Sometimes a normal restart of the computer is enough to fix the problem. So try it before you go any further.
Method 1. Check that the Required Services are running.
The first step to fix the "Wi-Fi doesn’t have a valid IP configuration" error, is to ensure that the required Network services are running.
