Is there a way to set preferred wi-fi networks in Android 6 Marshmallow (Galaxy S7)?

[Devon Greatwolf]

So, as the question states, I am looking to see if there is a way to set preferred wi-fi networks on my new Galaxy S7. I remember on the S2 (my last long lasting phone) there was an option to set priority for SSID's. I was hoping to find this as I frequently bounce in and out of my office at work and every time I return to my office my phone typically connects to one of the other tenants open xfinity or AT&T hotspot connections. I find this to be tedious as I have to manually reconnect to the correct network upon returning to my office in order to access our NAS and printers and for SideSync to pair with my desktop. This problem also occurs at my home as my phone tends to connect to the xfinity side of my modem instead of the private side or to my neighbors unsecured network and when I attempt to cast items to my TV, use my Vizio SmartCast app for my TV, or pair with SideSync on my desktop I am very seldom on the correct network and have to open up settings and reconnect. I have finally got my phone to forget the neighbors wi-fi, but I would prefer not to have to do the same for xfinity and /or AT&T as I tend to use those frequently when in the field. I thank you all for your time in reading this and I thank you in advance for any assistance you may provide.

Set it to not connect automatically to open networks. This is a good idea for a lot of reasons.
