When you go into the quick toggles (two fingers down from the notification bar) it will show the Wifi symbol as orange if it is connected but no internet while it will show white when connected and internet available.
The only thing that really bothers me about it is I find myself out of habit just glancing at the white symbols and thinking, "Oh crap, what's wrong with my internet" and just about the time I start to go into the settings I remember its supposed to be like that.
