Prevent iPhone from joining company wifi
I have a company issued MacBook Pro 15" Retina and a personally owned iPhone 6+ running iOS 8.2. My MBP automatically connects to the company's Wifi but my iPhone automatically connects as well. I've tried on the iPhone going to Settings --> Wifi ---> Clicked on wifi name and Forget This Network. But when I do this, the next morning, my MBP does not auto connect to the Wifi. If I join the Wifi Network on the MBP, my iPhone then automatically connects. I know everytime I go to work, I can turn off Wifi on my iPhone... but it's becoming a hassle... because I have a lot of home automation e.g. Lyric, Hue etc..
Is there a way, for my MBP to only connect to my company's wifi and not have my iPhone connect to it as well without turning wifi off?
Thanks in advance.
