When you receive an error message alerting you that your ethernet connection no longer has a valid IP configuration, it means that Windows is failing to receive the necessary IP address from the DHCP server, or Dynamic Host Configuration Protocol, a network protocol system that enables that server to automatically assign your computer an IP address for a specific network. This is like your home address: it makes it possible to track you through your internet usage. While devices have their own IP addresses, specific networks, like your home internet connection, all share a single IP address. Every device you own that connects to the internet can be identified by its IP address, a string of numbers assigned by your internet service provider (ISP) or mobile network provider (like Verizon Wireless or T-Mobile). Resetting Your IP Configuration Automatically.So what do you do when your ethernet-powered PC keeps delivering you error messages regarding the validity of your IP address? Let’s take a look. And usually, that’s how IP addresses work. Most consumers don’t think too much about the IP addresses powering their internet-connected electronics, and there’s a reason for that: IP addresses are boring, technical, and should mostly exist in the background.

So nothing is more frustrating than Windows alerting you to an invalid IP configuration. Ethernet makes all of this possible, while also providing a faster experience. PC gamers typically need as little interference between their computer and the network server as possible when playing online, and creative individuals working on media prefer a wired connection to upload files to the cloud remotely. Ethernet is generally more reliable than WiFi, especially when you’re actively performing a task that requires a stable internet connection. If you use a desktop PC, either for gaming or for work, you probably use an ethernet cable to supply internet to your PC.
