So, the wifi on my 5S has been behaving differently lately. Basically, it's connecting to any unprotected network it can. Before, it would only connect to wifi networks that I had explicitly told it to remember, and ignore everything else. Now anytime I walk by a Starbucks or something, it connects. This is annoying because these networks inevitably have some kind of a browser based login thing, and the connection doesn't actually work until you do that. So, if my phone happens to connect to one of these networks, my data basically ceases to work. I have but one theory as to why this is happening now: iCloud Keychain. Is it possible that I've connected to a Starbucks network with my MacBook at some point, and my phone is automatically connecting to it as a result? Do I have the right idea here? Has anyone else run into this? Any other ideas? Thanks!
