start wireless service on boot

[keesie]

I wrote a script called netup_boot to enable wireless on boot with systemd service.

This is the code of the netup_boot script:
$this->bbcode_second_pass_code('', '

#!/bin/bash
wpa_supplicant -B nl80211,wext -i wlan0 -c <(wpa_passphrase "my_essid" "mypasswd")
iw dev wlan0 link
dhcpcd wlan0

')

- I granted execution rights on the script
- chowned it to owner root:root
- copied the file to /usr/bin
- did $this->bbcode_second_pass_code('', 'systemctl enable dhcpcd.service')
- did $this->bbcode_second_pass_code('', 'systemctl start dhcpcd.service')
- created a service file in $this->bbcode_second_pass_code('', '/etc/systemd/system/netup.service')
- did $this->bbcode_second_pass_code('', 'systemctl enable netup.service')
- did $this->bbcode_second_pass_code('', 'systemctl start netup.service')

After (re)boot the status of $this->bbcode_second_pass_code('', 'systemctl status netup.service') shows:

$this->bbcode_second_pass_code('', '

')

The contents of the $this->bbcode_second_pass_code('', '/etc/systemd/system/netup.service') script are:

$this->bbcode_second_pass_code('', '
[Unit]
Description=Netup script

[Service]
ExecStart=/usr/bin/netup_boot

[Install]
WantedBy=multi-user.target

')

I know there are workarounds with wicd, wifi-menu, however I want to learn how to setup wireless networking this way.
I guess it is a runlevel issue? Or?
