I used an iPad and a MacBook to join a wifi network at work, and I just noticed that my 7+ was also connected to this network though I do not remember ever connecting to it. I selected the option to forget the network and it told me that it would no longer connect to this device or any other devices that are using the keychain. Does this mean that since I connected on my iPad it will connect using the keychain automatically on all my devices???? How do I turn this off so I can just connect on my iPad or Macbook without worrying about it also connecting my phone? Thanks.
