 Many people confuse not being able to connect to the internet with >>my website is not loading<< or >>my game cannot connect to its servers<<. But there are actually a lot of things, that can be wrong instead.

-The first step is finding out, if you are actually able to use other addresses or services. E.g. try browsing another website, start another program, that uses the internet. If it works, it is very likely not your internet connection, but the problem lies on the other end. If you want to check, whether others have the same problem, check out the page on [[https://downforeveryoneorjustme.com/]]. When a lot of others have the same problem, it is very likely not you, meaning you cannot do a whole lot about it. Either the server is down, your ISP has routing problems, or the server's network has issues. Bottom line is: If a lot of others have the problem, you just have to sit this one out. If seems to be just you, go to the next step.+The first step is finding out, if you are actually able to use other addresses or services.

 So you tried a few pages, but >>nothing on the internet works<< for you at the moment. The question is, can you actually reach anyone on the net? For this open a console of your choosing (on Windows that will probably be the cmd.exe or possibly the Power Shell). So you tried a few pages, but >>nothing on the internet works<< for you at the moment.

 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. So we just assume it is not down.) Head on to the next step. If you cannot reach the Google DNS server, your internet connection may indeed be down. But that must not be the case.

-You could not reach the Google DNS via its IP address but others don't seem to have you initial problem. The next step is finding out, whether the Internet connection is down, or something else along the way to the internet. If you for example cannot reach your own router (which routs the internet traffic to your computer and vice versa), you of course cannot reach the internet either.

 If the router actually does respond but you still cannot reach the internet, it means, that your local network seems to be just fine, but somehow the router is not routing any more. Very likely it is just the internet connection itself, that is down. You may have to open your router's configuration interface and try and reconnect to the internet. If the router actually does respond but you still cannot reach the internet, it means, that your local network seems to be just fine, but somehow the router is not routing any more.

-If the router is still not reachable, you may try restarting any switch, that is used in-between (they sometimes also hang). And if that also fails, you may try using another router (if you have a spare one). If someone messed up the settings, resetting it to factory settings and configure it anew might be necessary, too. If that does not help either (or you don't have a replacement at hand), there is on quick test, to see, if at least your computer isn't the problem: [[#Am I Listening to Myself? IP Stack Damaged]].+If the router is still not reachable, you may try restarting any switch, that is used in-between (they sometimes also hang).

 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 or ISP 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.
