So with all the internet issues going around and with Paul saying it's a router issue and your ethernet not working, there might be a simple fix if you are a pc user. If you're getting an error that says anything about contacting your Internet Service Provider (ISP) for a Domain Name Server (DNS) issue, do the following, and you should be fine. (Even if you're not sure if you have a DNS issue, you can just do this to cover all bases since it won't affect anything. Worst case scenario, it won't fix your internet issue).
- Turn off your wi-fi, and plug in your ethernet cable
- Go to the Start Menu > Accessories > Command Prompt
- Input "ipconfig /release" (no quotation marks)
- Then input "ipconfig /renew"
- Input "ipconfig /flushdns"
- Input "ipconfig /registerdns"
- Test your internet connection
