Comment # 20 on bug 1163771 from Freek de Kruijf

> Would you please try the latest Tumbleweed? 

I used 
openSUSE-Tumbleweed-ARM-XFCE-raspberrypi4.aarch64-2020.03.25-Build1.36.raw.xz.
Used tty1 <Ctrl>+<Alt>+<F1> to configure the system. Used "yast network" to
configure the wireless interface. wlan0 did not become active. So still a
problem. The configuration via yast showed management via wicked.
"iwlist wlan0 scan" did work and showed my access point, however no connection.

I created a user and started a XFCE session. There is a system tray icon for
the network. Started it and to my surprise - the configuration via yast is
still management via wicked - I could configure a wireless connection, which
did work. This connection is gone after leaving the XFCE session. This looks as
if NetworkManager is also active.

I hope this answers your request for more information.
