On my laptop I moved at some point to NetworkManager, but decided not to
use the GUI. I only use configuration files from
/etc/NetworkManager/system-connections .

$ cat /var/lib/NetworkManager/NetworkManager.state

[main]
NetworkingEnabled=true
WirelessEnabled=true
WWANEnabled=true


Be sure to enable the parts you want enabled (wireless, wwan) here.

I configure the wired network interface(s) in /etc/network/interfaces:

  allow-hotplug eth0
  iface eth0 inet dhcp

I also have some manual settings there.

Then you need a configuration file. The name of the file can be
arbitrary, but I name it the same as the name of the connection.

$ cat /etc/NetworkManager/system-connections/example_wireless_plain
[connection]
type=802-11-wireless
id=example_wireless_plain
# You MUST set a different uuid for each connection. Don't copy it:
# cat /proc/sys/kernel/random/uuid # or whatever
#uuid=8609b858-69b1-4ca6-adbe-7dcd47cb8711

[802-11-wireless]
ssid=TheirEssID


$ cat /etc/NetworkManager/system-connections/example_wpa2
[connection]
type=802-11-wireless
id=example_wpa2
# You MUST set a different uuid for each connection. Don't copy it:
# cat /proc/sys/kernel/random/uuid # or whatever
#uuid=ca9e4d19-a06f-4c7e-b0db-9f27c1792ba1

[802-11-wireless]
ssid=AnotherEssID
mode=infrastructure
security=802-11-wireless-security

[802-11-wireless-security]
key-mgmt=wpa-psk
psk=The Password



Those two stanzas covered some 99% of the cases for me. Scanning is
still more cumbersome, though. I never did get to autemate generating a
config. Shouldn't be complicated, though.

Sadly I did not see any progress in http://bugs.debian.org/637769 .
