Hi,
this is strange, because "dhcpcd" should be called automatically.
You can try to enable the service:
systemctl enable dhcpcd
If this does not work you can try switching to "dhclient":
pacman -Sy dhclient
and then add DHCPClient='dhclient' to your wifi profiles.
Description='wlan0 connection'
Interface=wlan0
Connection=wireless
DHCPClient='dhclient'
ForceConnect=yes
Security=wpa-configsection
IP=dhcp
WPAConfigSection=(
'ssid="NETGEAR"'
'psk="xxxxxxxxxxxxxxxx"'
'key_mgmt=WPA-PSK'
'proto=WPA'
'group=TKIP'
'pairwise=TKIP'
'priority=3'
)
