Hi! I've found that iOS7 seems to prefer to connect to secure APs even though these have weaker signals. My main AP one uses a MAC filter as security (we live out in the country side) however my iPhone 5 keeps choosing the other APs we have that are weaker. iOS6 didn't do this but rather tried to stay on the last one or strongest signal. It is a little bit frustrating. Does anyone know of any way to change this? It would be great if there was a way. Thanks in advance!
