Hi. I've been noticing something that happens with all of my iOS devices. Say I have a router that all of them are connected to. I then replace that old one with a new router, and configure it with the same SSID name. My iOS devices connect to the new one automatically even though I have a password set to it. My guess maybe it has something to do with the ISP? It is a PPoE connection, if it matters. How is this possible? I've changed 3 or 4 routers and this is always the case.
