My Wi-Fi says that it's connected but it won't load?

I have an iPhone 5s and it says that it is connected to my Wi-Fi, but whenever I try to use Instagram it says that IIm not connected to the Internet and whenever I try to search something on the Internet it says it's not connected even though it says it is.

Try to turn off Wi-Fi on your phone. Then turn it back on if that doesn't work that go to general--reset--and reset NETWORK settings. It will reset the Wi-Fi NOT your phone. You just need to put in the Wi-Fi password again. Glad to help fham

Try dis connecting, and connecting again, or try checking your Instagram, whether you have not activated to use internet for insta.
