[SOLVED] Systemctl start works, but systemctl enable displays FAILED

Hello again Arch forums!

I use wpa_supplicant to my wireless network. I created a systemd unit that works fine when I start it myself but gives me

[FAILED] Failed to start wireless network connectivity (wlp2s0).
See "systemctl status network-wireless@wlp2s0.service" for details.

when I enable it.
I ran

systemctl -l status network-wireless@wlp2s0.service

and got

● network-wireless@wlp2s0.service - Wireless network connectivity (wlp2s0)
   Loaded: loaded (/etc/systemd/system/network-wireless@.service; enabled; vendor preset: disabled)

Mar 14 16:05:39 archbox systemd[1]: network-wireless@wlp2s0.service failed.

I don't think this is an issue with my systemctl unit because

sudo systemctl start network-wireless@wlp2s0.service

works as it should.
I basically copied my systemctl unit from the wiki page, but here's what mine looks like:

[Unit]
Description=Wireless network connectivity (%i)
Wants=network.target
Before=network.target
BindsTo=sys-subsystem-net-devices-%i.device
After=sys-subsystem-net-devices-%i.device

[Service]
Type=oneshot
RemainAfterExit=yes

ExecStart=/usr/bin/ip link set dev %i up
ExecStart=/usr/bin/wpa_supplicant -B -i %i -c /etc/wpa_supplicant/Network_I_Am_Connecting_To.conf
ExecStart=/usr/bin/dhcpcd %i

ExecStop=/usr/bin/ip link set dev %i down

[Install]
WantedBy=multi-user.target

Here's what the wpa_supplicant conf looks like:

ctrl_interface=/run/wpa_supplicant
update_config=1
fast_reauth=1
ap_scan=1
network={
        ssid="Network_I_Am_Connecting_To"
        #psk="Wifi_Key"
        psk=27bef67e26069e38d40aec5981b47431bf442f2b76b84539d51edc8996548faa
}

Why isn't this working during startup, and how can I fix this?

[...]
Mar 14 16:05:39 archbox dhcpcd[403]: dhcpcd[403]: dhcpcd already running on pid 387 (/run/dhcpcd-wlp2s0.pid)

What is the output of:

ls -l /etc/systemd/system/multi-user.target.wants

Here's what came out of it:

Note that I rebooted at about 16:47, my time.

Re: [SOLVED] Systemctl start works, but systemctl enable displays FAILED

You need to disable the dhcpcd .service

# systemctl disable dhcpcd@wlp2s0.service

Then you should be able to `enable` your .service.
Then your .service should start up on boot.

EDIT: And the wpa_supplicant.service as well:

# systemctl disable wpa_supplicant@wlp2s0.service

They are all conflicting with each other -- you should only have one networking .service `enable`d at a time.
