Configuring router – what next?

Question

Hi, I've consulted the FAQ/guide and am a little bit lost as to where to go from here – I've installed Arch base ok and want to stick KDE on top of it but my internets not yet  configured (recognized) as I get "host temporarily unavailable when I try pacman –Sy or KDE etc. So I typed in hwdetect –show-net and got up
e100 eepro100 irtty-sir sir-dev mii ppp_generic slhc ieee80211 ieee8021
1_crypt irda ipw2100
(I take it the ieee80211 is my built in wireless which I won't be doing anything with - I have an IBM Thinkpad R40)
Now that I have this information, what do I need to do (type) to get connected?

Thanks for your comments - I would like to be a more competent Linux/command line user which is why I'm not giving up with this - I read through the Rc.conf wiki and edited the Network part from the default to the following then rebooted and still can't connect, what have i missed or gotten wrong?
# NETWORKING
HOSTNAME="myhost"
# Use 'ifconfig -a' or 'ls /sys/class/net/' to see all available
# interfaces.
# Interfaces to start at boot-up (in this order)
# Declare each interface then list in INTERFACES
# - prefix an entry in INTERFACES with a ! to disable it
# - no hyphens in your interface names - Bash doesn't like it
# Note: to use DHCP, set your interface to be "dhcp" (eth0="dhcp")
lo="lo 127.0.0.1"
eth0="dhcp"
INTERFACES=(lo eth0)
# Routes to start at boot-up (in this order)
# Declare each route then list in ROUTES
# - prefix an entry in ROUTES with a ! to disable it
ROUTES=(!gateway)
# Enable these network profiles at boot-up. These are only useful
# if you happen to need multiple network configurations (ie, laptop users)
# - set to 'menu' to present a menu during boot-up (dialog package required)
# - prefix an entry with a ! to disable it
# Network profiles are found in /etc/network-profiles
#NET_PROFILES=(main)
