Let me know if I can help any...but here is some of my config, obviously change the IP's
from the UI Network Config page (the last line I think was also important in making it work unplugged) - this file is /etc/netctl/eth0:
Description='eth0 static configuration'
Interface=eth0
Connection=ethernet
IP=static
Address='192.168.1.221/24'
Gateway='192.168.1.1'
DNS=('4.2.2.1')
SkipNoCarrier=yes
For wireless the file is /etc/netctl/wlan0-SSID_here (note: this isnt secure as the password is in clear-text. there is a way to encrypt the password to use....look it up
):
Description='A simple WPA/WPA2 encrypted wireless connection using a static IP'
Interface=wlan0
Connection=wireless
Security=wpa
ESSID='YOUR_SSID_HERE'
Key='In_normal_ASCII'
IP=static
Address='192.168.1.222/24'
Gateway='192.168.1.1'
DNS=('4.2.2.1')
# Uncomment this if your ssid is hidden
#
Hidden=yes
