NIS 2017- How to set laptop firewall to Public, and...?

Win7- NIS Newbie

I have 2 non-networked/Public FW (at least I don't think they are?)  computers on my cable router.

My desktop (I know is Public, with a buggy ESS IS AV (I will switch to NIS, once I get it figured out!)), and my NIS laptop (WiFy is disabled).

1. I am going on vacation, and want to use WiFy/Public FW- I can find nowhere in settings/PDF that tells you what your FW status is, or how to change it?

2. I also can't find out if I'm Networked, or Not (ESS does not like networking, and feels it is a security risk?).
