Hello,

on Leap 15.2 on my laptop network (eth and wlan) was working just normal.
Updated yesterday to Leap 15.3 and I have massive networking problems:

Feb 04 01:44:38 machine4 systemd[1]: Reloading wicked managed network interfaces.

Feb 04 01:44:40 machine4 firewalld[1364]: WARNING: NOT_ENABLED: wlan0

I've never seen this "NIC Link is Down" message, when the cable is plugged in and the switch is on.
On Windows 10 all is ok and this was working on SuSE Leap 15.2 just before update.
:-(

What is wrong here?
Reinstall?
Try tumbleweed?
Take another distribution and leave SuSE?
