If this works, your general internet connection setup is actually OK, but the configured DNS server to be used by your computer may be faulty. Either there is a DNS server manually configured, that does not respond any longer. If so, remove the manual configuration (see section [[#My Little Island (Wrong IP Configuration)]] on a very similar matter). Usually the DNS server to be used is provided by your router at the same time, your client gets its IP address assigned by the routers DHCP server. So getting it automatically should usually be fine. Or the DNS server has a problem itself. | If this works, your general internet connection setup is actually OK, but the configured DNS server to be used by your computer may be faulty.

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.

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.
