Wow mine connects fast enough for me never to notice if was off in the first place. I haven't had to go into settings to connect after initial set up.
This has been my experience as well. I use WiFi at home and at work every day and my Lumia switches seamlessly between the two from sleep without me doing anything, it takes a few seconds to connect, but not long, literally like 2 sec.
Not sure if it's related to the update Nokia pushed out last week, but have you tried that?
It's possible it may have something to do with your schools wireless network too, I suppose.
