[Pkg-utopia-maintainers] Bug#1107527: network-manager: Fails To Display Available WIFI HotSpots

[Jolly Roger]

Package: network-manager
Version: 1.42.4-1+deb12u1
Severity: normal
X-Debbugs-Cc: kitchm at tutanota.com

Dear Maintainer,
I cannot get my fresh install of Debian 12 environment to display available
WiFi networks.

The computer is the Lenovo ThinkPad X1 Yoga (Gen 2) i7 7600U 2.8Ghz 14 2-in-1
Convertible Laptop.
Dual-boot; Windows 10 Pro and Debian 12

The iwlwifi firmware driver seems to be working and up to date.

Windows sees GUI of network connections and displays all available WIFI
networks.  Network working fine; both with VPN engaged and without.

Debian’s systray icon shows no WIFI connection and none available.  But network
is working.

The access point does not see any connections from the laptop (whether in
Windows or Debian), which is the only wireless device.)

The systray applet shows 'device not managed'.  Editing
/etc/NetworkManager/NetworkManager.conf and changing ‘managed=’ to ‘true’,
changes applet to show 'device not ready'.  There is no other change, but when
activated, the network gets disconnected.

Removed ifupdown package, but still referenced in conf file.  No network
connection.  Tried nm-tray, but just added another like NetworkManager Applet
and a lot of other libraries.  Had to undo manually, and put all back like it
was.  Network started working again.

Here are some details:
