Network Connectivity Fails to Start On Boot

I've acquired a new Lenovo IdeaPad 320S, Intel Quad Core i5.

I set to install Arch, using notes I've used on previous machines many times and updated each time.  I've had issues getting WiFi to work before, but always had a RJ45 wired connection to fall back to, where I'd set up a netctl profile, enable it, and issue

sudo dhclient

. It always worked fine, even after boot.

I did the same here, but it would not work.  Now I've manage to get it working, reliably, but not after each reboot, without

ip link set interface X down

,

wifi-menu -o.

How can I get the wifi to work on boot.  My progress/attempts are below.  I've tried to get as ,much info, following the main Network Config Arch Wiki and the Wireless Wiki.  They get me UP, but I can't seem to get WiFi working on boot.  Let me know if there's anything else I can provide to complete the picture.

pacman -S iproute2 wpa_supplicant

Get name of Wireless Interface

iw dev

Bring interface up

ip link set wlp2s0 up

Check Interface/Connection

ip link show wlp2s0

   link/ether 64:6e:69:f8:71:b3 brd ff:ff:ff:ff:ff:ff

Check for Access Points

iw dev wlp2s0 scan | less

Find Specific Wireless Connection

iw dev wlp2s0 scan | WiFiConnection

Disable Power Saving on Interface

iw dev wlp2s0 set power_save off

Connect to WiFiConnection

wifi-menu -o

Successfully connects, creates profile in /etc/netctl, sometimes requires following line first:

ip link set wlp2s0 down

Edit Profile

Enable Connection

sudo netctl enable wlp2s0-WiFiConnection_5Ghz               
The profile ‘wlp2s0-WiFiConnection_5Ghz’ is already enabled

Connection is stable, lets reboot to check status afterwards…
After Reboot

ping google.co.uk
Temporary failure in name resolution
ping 8.8.8.8
connect: network is unreachable

Re: Network Connectivity Fails to Start On Boot

Please paste the output of `systemctl list-unit-files -state=enabled`.

Not an Installation issue, moving to NC...

Re: Network Connectivity Fails to Start On Boot

netctl@.service is not in the list.  What is the status of wlp2s0-WiFiConnection_5Ghz now?

Re: Network Connectivity Fails to Start On Boot

I've now also tried

systemctl --type=service

, showing

netctl-auto@wlp2s0.service    loaded active running

, but at the time it was FAILED, FAILED. 
There was also an enabled entry for the netctl profile, which is FAILED/FAILED on boot, but if I bring the interface down, then do

wifi-menu -o

it works.  I disable the netctl profile, leaving just the netctl-auto.

I then (five min ago) came across a StackExchange https://unix.stackexchange.com/question … atic#83108 which mentioned ensuring wpa_actiond is installed, which I've not seen mention anywhere.
I've installed wpa_actiond and rebooted and hey presto, it works on reboot.  Even within KDE.
