Netfox's Wi-Fi tool puts a padlock beside every network: green and closed when the traffic is encrypted, red and open when it isn't. Version 0.29.0 added a third case, Enhanced Open (OWE): a network you join without a password whose traffic is still encrypted. It deserves the green lock, and the join sheet tells you so.
A day after shipping it, I filtered the list to "No password" and saw two networks with a green closed padlock. One, by the look of its name, was a neighbour's smart vacuum showing its setup hotspot. Its radio didn't even do 802.11n, and it was supposedly speaking a protocol from 2018. system_profiler SPAirPortDataType agreed with my suspicion: Security: None. Netfox said Enhanced Open, Open.
New module shipped, and it answers one question without a terminal, a router admin page or a speed test: is my connection the problem, or is it something past my door?
Until now the Wi-Fi tool could tell you your channel was busy or your signal weak and then send you off to the menu bar to do something about it. Not anymore:
Netfox has always found devices by listening. This release lets it ask.
Your network has things on it that never say a word. A printer asleep. A camera that only ever talks to its own cloud. A Pi you set up in March and forgot. They are powered on and perfectly reachable, and until now Netfox could not show them to you not because it was hard, but because everything it knew came from whatever announces itself, or whatever has already spoken to your Mac.
