Alternative would be knowing that a lot of 'old' control panel UIs are accessible through the new one, so: go into the new settings UI to network-related stuff (Win-x, w or Win-X, n and start typing 'network') and there will be 'change adapter settings' somewhere. Or possibly you can change the setting you want from the new UI.
Which indeed shows this particular par was turned into a mess. But as the OP says: I haven't actually been bothered by it a lot myself. Likewise for some UI parts looking different: it has been like that since as long as I can remember on computers, no matter which OS or whether it's a CLI, TUI or GUI: if you use more than a couple of tools there are always going to be tools which look and/or do things in a different way. So people kinda get used to that anyway. Not that it's an excuse for doing this to an OS, but just looking at it from the practical side.
Also -- it looks great! Why isn't that an option somewhere in Control Panels?
The wifi and hotspots are in metro ui setting app.
Interfaces are in its own standalone app. (win7 style)
However... The firewall are in a xp style standalone app.
Can't they combine them into one app or at least make a folder that contains link to them?
