[Pkg-utopia-maintainers] Bug#841392: loses WLAN if location changes while suspended

[Marc Haber]

Package: network-manager
Version: 1.4.2-2
Severity: normal

Hi.

I am at home, connected to my home WLAN. I suspend the box (to RAM),
carry it to work. I wake up the box from suspend.

In this situation, nmtui reliably does not offer any WLAN connections.
nmcli says that wlp3s0 is "unmanaged".

After I restart Network-Manager, wlp3s0 is "disconnected" and can be
connected with nmtui.

I am using KDE, but have plasma-nm unistalled to keep KDE/Plasma
from interfering with network-manager to make sure this behavior is a
genuine network-manager issue.

I am prepared to debug if you can tell me what to do.

Greetings
Marc
