Netctl, ip and drivers issue for ethernet and wlan

Question

Hi,
I recently installed the version of archlinux with netctl instead of netcfg.
During the installation I think I've used netcfg and it was all running smoothly. Then I wanted to configure my connection on the system, but it's impossible in all the ways I tried. I followed the beginner's guide then copied the wireless-wpa profile from the examples folder to the netctl folder, then
sudo netctl start profilename
. I've also
sudo ip link set wlp4s0 up
but then i got with the show option:
3: wlp4s0: <NO-CARRIER, BROADCAST, MULTICAST, UP> mtu 1500 qdisc state DOWN mode DEFAULT qlen 1000
link/ether 68:a3:c4:df:17:8e brd ff:ff:ff:ff:ff
I get the same result with enp2s0. I've already run dhcpcd.
Then I controlled drivers. I have a ralink rt5390 card and it's using rt2800pci. Ethernet card it's realtek rtl8111/8168 and is using r8169. How can I connect to the internet? I need it, thanks in advance.
Ps: sorry for my terrible English, I'm Italian

I'm not on my Arch machine at the moment, but let's see if we can fix this.
For the moment, try setting up your wired connection first. If you are sure your wired device's name is [enp2s0] then (run as root):
You might want to kill DHCPCD before starting.
# systemctl start dhcpcd@enp2s0 <---this is to enable DHCP for your wired connection
# systemctl enable dhcpcd@enp2s0 <---this is to enable DHCP automatically at boot
# dhcpcd
