I am running the latest iOS9 and El Capitain betas on my iPhone and mac. I would like to forget a wifi network on my phone but not my computer. We are on satellite internet at the office that is brutally slow with limited bandwidth so I don't want my phone connecting to it. If i try to forget the network on my phone, it boots me off on my mac. Is there a way to forget the network on the phone but keep the computer connected?
