Fresh Install, eth0 device not found

[contraversy]

Ok, it's late, and im aggrevated, but heres what is going on.

I decided to tackle the gentoo install today, and went flawless, up until now...
With the livecd, and I followed the handbook 100% as far as I can tell, but after the install I have no network connection.

I have searched high and low on google and this forum, and have followed many threads, none of which have resolved my issue.

lpsci <-- does not work for me, get command not found
Running: linux-3.2.12-gentoo

ethernet device is Atheros AR8121 and I have it selected in my makeconfig.

networking worked great on the live cd, and I cannot emerge any packages cause of no connection, and my modprobe's seem to error also ( unless i am doing something wrong and im sure i am)

emerge dhcpd errors (assuming it requires a network connection, cause i see it using wget in the logs)


my /etc/conf.d/net:
config_eth0="dhcp"

i have ran:
# cd /etc/init.d
# ln -s net.lo net.eth0
# rc-update add net.eth0 default

my ifconfig -a shows

lo Link encap:Local Loopback

any help will be appreciated
thanks

lspci is part of pciutils
you should emerge this from a livecd after youve mounted/chrooted

the non-existent eth0 is undoubtedly something missing from the kernel, and unfortunately to tell you what it is, we need to see lspci output (or if you want to have a gander at the link in my sig, lspci -n output)

start with that - get lspci working, get us output, go from there

modprobe is for modules
if you have your NIC driver as a built-in, (=y) then it would not be something you load via modprobe

if you're certain you have the right driver selected, either as a module or as a built-in (modprobed if the former), check 'cat /proc/net/dev' and see if it's there. I doubt it is, and 10 times out of 10 if the interface is missing from /proc/net/dev it means either driver, firmware, or busted card. Since you were able to do the install from a livecd, it aint a busted card

From what Google has informed me, you should have this:

thanks man, but i have one quick question before i tackle this.

if i boot with the livecd, and emerge pciutils, does it only emerge it for that session? (like my network drivers were)
How do i emerge it from the livecd but on my gentoo installation?

contraversy,

pciutils will be installed to your gentoo installation if you're chrooted to your gentoo installation from the live cd.

Since installing gentoo, my life has become one long emerge

Ok so I chrooted using this guide: http://forums.gentoo.org/viewtopic-p-3516331.html

my prompt is {chroot} livecd / #

but when i try to emerge dhcpd or emerge pciutils it fails and outputs a log file and when i nano -w the log file it is blank..


also when i type cat /proc/net/dev
i get 2 devices "lo" and "sit0" but eth0 has '0' through all tables

my # ls /lib/modules/linux-3.2.12-gentoo/kernel/drivers/net didnt have an atheros folder, probably because i didnt select it when i did the first install and make.
now that I am on the livecd, i see the folder listed, so im going back through the menuconfig and make && make modules_install

*edit* i now have an atheros folder in /lib/modules/<kernel>/kernel/drives/net/atheros

ok im chrooted, and got net-setup to run, i now have a network ip address on eth0, and can ping my router. but emerge dhcpd is not found, and if i emerge pciutils it tries to fetch and fails connection

contraversy,

Are you mounting and binding /dev? This is how I chroot to mine when I have a catastrophic error
