Hi, i've asked before for help on this and tried following the guide that was given. Though i'm still coming up short with a solution. I'v re-installed gentoo and found a lot of errors i had, unlike before i did not genkernal all to config my kernel i configured it myself using gentoo wiki for my laptop (1000HE asus). I also read a few other topics about wpa_supplicant and got that thing figured out. Here is what im dealing with.

eth0 and wlan0
Code:
*  ERROR: interface eth0 does not exist
*  Ensure that you have loaded the correct kernel module for your hardware
*ERROR: net.eth0 failed to start
*ERROR: cannot start netmount as net.eth0 would not start

Code:
*  ERROR: interface wlan0 does not exist
*  Ensure that you have loaded the correct kernel module for your hardware
*ERROR: net.wlan0 failed to start
*ERROR: cannot start netmount as net.wlan0 would not start


Code:
lspci -k

heres the website to see it.
http://bpaste.net/show/115298/

Also did this command
Code:
touch /etc/udev/rules.d/80-net-name-slot.rules


and my genkernel --menuconfig all is set to this *helped set up by Donahue*

Code:
[*] Networking support --->
-*- Wireless --->
--- Wireless
<M> cfg80211 - wireless configuration API
[*] cfg80211 wireless extensions compatibility
<M> Generic IEEE 802.11 Networking Stack (mac80211)

<M> RF switch subsystem support --->

[*] Atheros bluetooth coexistence support (NEW)
<M> Atheros 802.11n wireless cards support
[*] Atheros ath9k PCI/PCIe bus support (NEW)
[*] Atheros ath9k rate control (NEW)


Code:
wgetpaste /mnt/gentoo/usr/src/linux/.config

website to it
http://bpaste.net/show/115299

ive also did
Code:
emerge pciutils iw wireless-tools wpa_supplicant dhcpcd linux-firmware


set up this thanks to *Donahue*
[quote="DONAHUE"]when back up you should have
Code:
ifconfig -a
showing eth0 and wlan0 or new names courtesy of udev. presuming eth0 and wlan0 are still in use:
Code:
cd /etc/init.d
ln -s net.lo net.eth0
ln -s net.lo net.wlan0
rc-update add net.eth0 default
rc-update add net.wlan0 default
nano /etc/conf.d/net
edit to
Quote:
modules_wlan0="wpa_supplicant"
wpa_supplicant_wlan0="-Dnl80211"
wpa_timeout_wlan0=30
iwconfig_wlan0_mode="Managed"
config_wlan0="dhcp"

config_eth0="dhcp"
and
Code:
nano /etc/wpa_supplicant/wpa_supplicant.conf
edit to
Quote:
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
update_config=1
then
Code:
/etc/init.d/net.eth0 restart


I get this
Code:
*Bringing up interface eht0
*   ERROR: interface eth0 does not exist
*   ENSURE that you have loaded the correct kernel module for your hardware
*ERROR: net.eth0 failed to start


any help would be greatly appreciated

EDIT: when i do the following command upon reboot (gentoo is installed just trying to get the internet up and going)
Code:
# ifconfig -a
lo: flags=73<UP, LOOPBACK, RUNNING> mtu 65536
     inet 127.0.0.1 netmask 255.0.0.0
     inet6 ::1 prefixlen 128  scopeid 0x10<host>
     loop txqueuelen 0 (Local Loopback)
     RX packets 0 bytes 0 (0.0. B)
     RX errors = dropped 0 overruns 0 frame 0
     TX packets 0 bytes 0 (0.0 B)
     TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

The ifconfig - a results suggest that drivers are not in your kernel for ethernet and wifi NIC's. Boot installed gentoo. Mount the /boot partition. Edit your menuconfig to include the following:
Quote:
[*] Networking support --->
-*- Wireless --->
--- Wireless
<M> cfg80211 - wireless configuration API
[*] nl80211 testmode command
[ ] enable developer warnings
[ ] cfg80211 regulatory debugging
[ ] enable powersave by default
[ ] cfg80211 DebugFS entries
[*] cfg80211 wireless extensions compatibility
<M> Generic IEEE 802.11 Networking Stack (mac80211)
Default rate control algorithm (Minstrel) --->
[ ] Enable mac80211 mesh networking (pre-802.11s) support
-*- Enable LED triggers
[ ] Export mac80211 internals in DebugFS
[ ] Trace all mac80211 debug messages
[ ] Select mac80211 debugging features --->

<M> RF switch subsystem support --->

Device Drivers --->
[*] Network device support --->
[*] Ethernet driver support --->
--- Ethernet driver support
[*] Atheros devices
<M> Atheros L1E Gigabit Ethernet support

[*] Wireless LAN --->
--- Atheros Wireless Cards
[*] Atheros bluetooth coexistence support (NEW)
<M> Atheros 802.11n wireless cards support
[*] Atheros ath9k PCI/PCIe bus support (NEW)
then recompile the kernel, recopy the kernel to /boot, reboot.

ok so if i used system rescue cd to install gentoo i boot into system rescue cd and mount my /boot partitions which would look like this? (would i need to chroot?)

Code:
mount /dev/sda1 /mnt/gentoo
mount /dev/sda3 /mnt/gentoo/boot


from there i do the following?
Code:
make menuconfig


fix my menuconfig to look like the one quoted and recompile it.

how do i recopy the kernel to /boot?

after my menuconfig has saved, I use
Code:
make && make modules_install && make install
which compiles kernel and installs the kernel in /boot using a name like vmlinuz-3.10.1-gentoo
the handbook uses cp arch/x86/boot/bzImage /boot/<whatever name you choose but suggesting a form like kernel-3.10.1-gentoo> note that some bootloaders look for the kernel using vmlinuz or kernel as keywords
as your post said the installed gentoo was bootable I had assumed you would boot it, however using the chroot is perfectly fine for your purpose. step by step for each:

Either:

boot the installed gentoo
Code:
mount /boot

Code:
cd /usr/src/linux

Code:
make menuconfig

make changes and exit saving configuration
Code:
make && make modules_install && make install

edit /boot/grub/grub.conf to add an entry for the new kernel

Or:

boot the sysresccd,
Code:
mount /dev/sda1 /mnt/gentoo
mount /dev/sda3 /mnt/gentoo/boot
enter the chroot:
Code:
mount /dev/sda3 /mnt/gentoo
mount /dev/sda1 /mnt/gentoo/boot
mount -t proc none /mnt/gentoo/proc
mount --rbind /sys /mnt/gentoo/sys
mount --rbind /dev /mnt/gentoo/dev
chroot /mnt/gentoo /bin/bash
source /etc/profile
export PS1="(chroot) $PS1"
edit menuconfig
Code:
cd /usr/src/linux
make menuconfig
compile and install the kernel
Code:
make && make modules_install && make install
edit grub.conf to add an entry for the new kernel, then make a graceful exit
Code:
exit
cd
umount -l /mnt/gentoo/dev{/shm,/pts,}
umount -l /mnt/gentoo{/boot,/proc,}
reboot

edit grub.conf to add an entry do i # the current /boot/kernel and write a new one?

just add a new menu item with anew title and a new kernel name example:
original:
Quote:
default 0
timeout 5
#splashimage=(hd0,0)/boot/grub/splash.xpm.gz

title Gentoo 3.9.10
root (hd0,0)
kernel /boot/vmlinuz-3.9.10-gentoo root=/dev/sda3

title Gentoo 3.10.1
root (hd0,0)
kernel /boot/vmlinuz-3.10.1-gentoo root=/dev/sda3

then boot the second choice on the reboot
if it fails you still have the first known working choice as a backup
