Here's something a bit strange that I didn't notice before. I have both 2.4ghz and 5ghz wifi networks in my house. I like to use the 2.4 band for my iPhone and the 5G band for my mac. When my iPhone reconnects it chooses the 5G because I have that set on my Mac. OK, so I forget the 5G band on the iPhone and connect to 2.4G band. Later when I open my Mac and connect it chooses the 2.4G band. So I go and choose the 5G band and it asks for a password. Is there a reason why the wifi settings are syncing between the iPhone and Mac? If so can I turn that off.
