Very seldom, a computer actually has *no* network connection. Much more often, you have a network connection, but it's not very useful. For example, you might have full network connectivity... but only on localhost. Or you might be on a LAN, and fully able to access its resources, but your uplink to the rest of the internet is down. Or maybe you're a server inside Facebook, and the rest of the internet is slowly getting disconnected from you. Do you have an internet connection? Do you have what you need? *There is no way* to answer the question of whether you have internet access, other than to try the exact thing you want to do, and see if it fails. People who think that there's a binary state of "have internet" // "do not have internet" have clearly never worked in networking.... (No, I've never accidentally misconfigured a network so that we had full access to everything *except* the local network. Why do you ask? Anyway, I fixed it within a few minutes.)
