So I noticed my new Note 2 would automatically connect to any nearby att hotspot, whether it was a good connection or not. Like last night at a restaurant with a starbucks nearby. I was too far away for a meaningful connection, but close enough for a signal that made the phone connect automatically. I finally dug in enough and found a check box under wifi advanced settings that allowed me to uncheck the auto connect for this. Hopefully someone will find this helpful, I was unhappy with it because I dont like to connect to any public wifi spots if I can help it.
