According to your other thread, sounds like the WiFi is connected, but it's got some sort of landing or login page. What's that stuff about "Terms and Conditions". That doesn't sound like regular home WiFi. Who's T&C? Is this in a restaurant, mall, hotel, airport or something? Might be worth you contacting the admin of whomever is running it, see what's going and what might be needed. Sure you got the right password. The connect might be greyed until you've entered a minimum number of characters for the password, or whatever other credentials it needs.
