This is a problem that occurs often (but not always) on my Windows 10 laptop... I turn it on and connect to a wi-fi network; and I get the icon that means "connected, but no internet". When this happens, I go to the "Network connections" and look at the Wi-fi properties. Under TCP/IPv4, I find that it is set to "Obtain IP address automatically"; but the DNS server address has reverted to an old (and incorrect) DNS address that I had once entered manually. I click the box that says "Obtain DNS server address automatically", click OK, and then all is fine -- until this happens again.
How can I get my system to forget that old, wrong DNS address once and for all?
@naarzan This will purge the DNS cache but not change the configured DNS server – Benjamin Hastings – 2017-02-20T22:23:51.063

Before you setup your DNS as Static or Dynamic from your PC run this command, to clear the "cash" if something stuck it will solve that, check this documentation https://technet.microsoft.com/en-us/library/cc794721(v=ws.10).aspx
– Narzan Q. – 2017-02-20T22:26:47.3171Thanks. I did this (@benjamin hastings: after I had reconfigured TCP/IP so that it works correctly) and received the message you indicated. Since this solution looks very promising, I went ahead and accepted this answer. You can be sure I will angrily uncheck it if the problem recurs :-) in the future! – Russ Lenth – 2017-02-20T22:32:22.253
