I used Maui since inception on both desktop and laptop computers. Using an ‘USB Aircard’ (mobile broadband) connection or Wi-Fi was as easy as pie as all the relevant connection services were displayed in Network Connections together with a number of other network connections within close vicinity of my router.
It was not necessary to create a new connection as they were already displayed in the Networks window and needed only a click of the mouse to change.
The network connection manager in Netrunner 19.01 (Edit your Network Connections) does only display my wired connection and won’t sense/detect any other available Wi-Fi connections.
It seems that either your wifi chip was not detected or the firmware for it is missing.
Best to find out is running inxi -v4
and see what it lists as network devices. If your Wireless Network device appears its a good sign as it detected the card in general.
Maybe you can post the output here and I will do a research to see if this Wifi Chip is going to work on Netrunner.
Usually it should when it was working fine on Maui before, so you only need the right firmware files which might be missing.
I found the solution to this pesky problem.
The puzzler was solved in a blink of an eye after enabling the Wireless radio button in System Settings --> Power Management. Available Wi-Fi conections are now showing in the Networks drop-down menu.
