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.
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:
Every Wi-Fi tool shows you numbers. Signal, noise, a channel number, maybe a chart. Then it leaves you there because the numbers were never the question. The question is is my Wi-Fi the problem?
