How complicated can it be? (Wi-Fi)

[kpanic]

Hi,

I was looking for the services, which start when the boot process reaches the
graphical target and found this:

Code:

systemctl list-unit-files --state=enabled

And the output looks like this, when sorted by directly network related services:

Code:

dbus-fi.w1.wpa_supplicant1.service         enabled  1
wpa_supplicant.service                     enabled  1
dbus-org.freedesktop.network1.service      enabled  2
systemd-networkd.service                   enabled  2
dbus-org.freedesktop.resolve1.service      enabled  3
systemd-resolved.service                   enabled  3
dbus-org.freedesktop.nm-dispatcher.service enabled  4
NetworkManager-dispatcher.service          enabled  4
network-manager.service                    enabled  SL
NetworkManager.service                     enabled  SL
networkd-dispatcher.service                enabled
resolvconf-pull-resolved.path              enabled
resolvconf.service                         enabled
networking.service                         enabled
NetworkManager-wait-online.service         enabled
systemd-networkd-wait-online.service       enabled
apport-forward.socket                      enabled
systemd-networkd.socket                    enabled
pppd-dns.service                           enabled
dns-clean.service                          enabled

....

I mean, how hard can it be to setup one wlan interface?
Years ago there was one init script under /etc/init.d which configured the
interface and that was it. But now we have this mess of mumbo-jumbo that
I don't understand.

Can someone check if this configuration has "some" overhead in it, please?
I use a laptop and my intention is just to get my wlan interface configured via dhcp.
Do I really need all of these units and services?

I added a number after those services which are related dbus < systemd
The "SL" means that the other is a symlink to the other one.

Thank you in advance!
