Hi JadeTheDog1,
Thanks for trying out our beta and you shouldn't worry about responding to your own post (its helpful!). We've idenitified an issue with adapters such as this, and the problem should be fixed in our next update. When this update comes, such adapters will still default to a "Public" setting due to the nature of such adapters, but if you change it to a "Home/Work" network, the firewall settings should change appropriately.
If the problem persists, or you believe your problem is different from the other "Identifying" adapters issue, please send us your support logs as per the instructions here: https://connect.microsoft.com/site/sitehome.aspx?SiteID=168
Thanks again!
-John
