Associated with Wi-Fi, But No Internet Access in Windows?  IT Idiots network tricks

                        

Command Prompt Commands
 Windows features several networking commands in the Command Prompt. You should attempt a few of them when you have no internet access in Windows 10. Type cmd into the Start Menu, then right-click on it and choose Run as administrator to open an elevated Command Prompt window.

To reset some of the files Windows keep to access the internet, use these two commands:

netsh winsock reset
netsh int ip reset

If that doesn't work, try releasing your computer's IP address and obtaining a fresh one with these two commands, one at a time:

ipconfig /release
ipconfig /renew

Finally, refresh your computer's DNS settings with this command:

ipconfig /flushdns

It doesn't hurt to reboot your PC again at this point. If you still have no internet access, there are a few more steps to try.
