Model # R7450 AC2600 wifi not connecting with internet

[dolphinacf]

I have my internet connected through ethernet and have the router up and running with all options lighting up white saying good to go but when trying to connect to it through wifi i get connected but no internet.  What can i check or try to get it up an running?

I also tried resetting it and hitting the button on wifi to make sure it is all good.  I just purchased it yesterday and set it up.

As well as the questions from @plemans, wifi on what? A mobile phone? A laptop? Something else?

Where do you get this message? A browser? What is the exact wording?
