So I have been having this problem for a while now. I'm going to give you guys a step-by-step process that I did in order to be as understandable as possible. Earlier today I was doing some school work on my computer. As I was working I was disconnected from the Internet. My computer usually randomly disconnects sometimes, but most of the time I would fix this by using the troubleshooting option in the Settings menu. I did this and I reconnected. However, I was still getting the connection error message. So I decided to open up the command prompt and renew/release the IP. However, whenever I entered ipconfig /release I was disconnected. This happens every time I execute ipconfig /release. I then troubleshooted and was reconnected with connection errors still popping up. I then decided to troubleshoot while repeatedly typed ipconfig /release into the command prompt. The troubleshooter finished and said that Ethernet doesnt have a valid IP configuration. Please help I'm not sure what to do now!
