 If you cannot reach the Google DNS server, your internet connection may indeed be down. But that must not be the case. (Yes, Google may also be down, but that is very unlikely.

 The greyed out elements are the network cards currently deactivated. If you find, that your LAN or W-LAN adapter is actually just deactivated, that would also explain, what is going on. (In the example, the wireless connection is deactivated, the wired connection is active.) In such a case, just activate it (right-click --> //Activate//, may need administration privileges) and recheck. The greyed out elements are the network cards currently deactivated.

 If your computer does answer to itself, then the computer is (usually) just fine. So it's either the router, that does not answer, or you still have a configuration problem of your IP settings. It may also be possible, that you have to configure your IP connections manually. But that usually is done by someone managing your network. So you will have to refer to that person. If your computer does answer to itself, then the computer is (usually) just fine.

-There is still one other direction this can go. You can open //<nowiki>www.google.com</nowiki>// just fine, but other hosts IPs are simply not usable. It's not the DNS server, it resolves just fine. As you ruled out that others have the same issue (first step), this problem my lie in a firewall or proxy server or maybe a parental control put in place, that prevents you from reaching specific hosts on the internet. Usually there is not much you can do about that, unless you administrate that kind of infrastructure yourself. (But then again, you would not have come here for solutions on your problem in the first place...) If this is actually somehow malfunctioning (you don't see any reason why this specific service or page is being blocked for you), try and contact your network administrator about the issue.+There is still one other direction this can go.

 So your router responds and the web interface is accessible, but the internet connection still refuses to work. This is usually a problem of your ISP. You may have to live with it, until they fix it. If it does not go away, even after a few hours, try contacting your ISP on the problem. Usually it is nothing you can influence. Worst case scenario: The wiring of your home or of your carrier is defective, which requires a technician to fix the problem. Or the Router is damaged, and needs to be replaced. So your router responds and the web interface is accessible, but the internet connection still refuses to work.
