my network/interfaces file

interfaces

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# NOTE: there MUST be only ONE (1) gateway, even over wirless, dhcp, static...
#		there is a workaround, assigning different gateways "metrics" (qv). dragons

#sdm# this is reccomended on https://wiki.debian.org/WiFi/HowToUse which is the
#		least-resistance path to getting wifi going

# The loopback network interface
auto lo
		iface lo inet loopback
 
# auto eth0
# iface eth0 inet dhcp



# auto eth0
# iface eth0 inet static
#         address 192.168.1.66
#         netmask 255.255.255.0
#         network 192.168.1.0
#         broadcast 192.168.1.255
#         gateway 192.168.1.1

##If you want NetWorkManager to manage your wireless connection, 
## then you need to clean up the /etc/network/interfaces so that the file
## only contains the following 2 lines:
##
## auto lo
## iface lo inet loopback
##
## If you add more configuration lines, 
##  then the NetworkManager icon will not work correctly anymore.
