Netctl fails with "link is not ready"

Question

Hi all
I was hoping that you can help me out! I'm new to archlinux so please accept my apologies if I've missed something obvious.
I've just setup a new archlinux system on my HP N40L according to the archwiki beginner's guide and this btrfs guide.
I want to automatically connect to the internet with a static ip via ethernet cable.
netctl setup
cp /etc/netctl/examples/ethernet-static /etc/netctl/ethernet
nano /etc/netctl/ethernet
netctl start ethernet
netctl profile
Description='A basic static ethernet connection'
Interface=enp2s0
Connection=ethernet

#Routes=('192.168.0.0/24 via 192.168.1.2')
Gateway='192.168.1.1'

I can connect if I use these commands so there's no physical problem with hardware.
ip link set enp2s0 up
ip addr add 192.168.1.200/24 dev enp2s0
ip route add default via 192.168.1.1
or
systemctl start dhcpcd@enp2s0
I also tried to bring the interface up first.
ip link set enp2s0 up
netctl start ethernet

LOAD = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB = The low-level unit activation state, values depend on unit type.
58 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.
My modem router (192.168.1.1) handles DNS and DHCP (192.168.1.2 - 192.168.1.254).
I tried change the address pool to 192.168.1.2 - 192.168.1.253 and setting my computer's ip to 192.168.1.254 to avoid possible conflicts but this made no difference.
I have only installed packages from the base group and the packages openssh, amd-ucode and btrfs-progs.
thanks for the help - hopefully it's something simple I've missed
EDIT
I've found out that the following works
pacman -S ifplugd
systemctl start [email protected]
does anyone know why the beginner's guide wasn't working for me? is there a bug with netctl?

Answer 1

Thanks for the pointer Lone_Wolf.
I've opted for the method you linked to as it means I can remove netctl and ifplugd.
[Unit]
Description=Wired Static IP Connectivity
Wants=network.target
Before=network.target

ExecStart=/usr/bin/ip route add default via 192.168.1.1
ExecStop=/usr/bin/ip addr flush dev enp2s0
ExecStop=/usr/bin/ip link set dev enp2s0 down
[Install]
WantedBy=multi-user.target
I guess this is a solution sorts, although the original issue remains unsolved.
Is it worth cross posting to netctl on git?
