I don't know why this is downvoted. This is Hacker News, a hacker always uses the least amount of effort (the least number of lines of code for example) to achieve his goal.
Windows key + R / "cmd" / Return / "nslookup google.com" then when that fails, "ping 8.8.8.8" and when that fails, "Ipconfig /ALL", then ask "Do you use Dhcp or are ip's assigned?" as I reboot the computer and check the physical connections at the same time.
