[SOLVED]eth0 and wlan0 do not exist

ifconfig -a gives me me lo only. This is after a clean install with the new installation. With the previous installation everything worked fine until i updated the kernel and then my eth0 and wlan0 would disappear. I have looked at this thread http://bbs.archlinux.org/viewtopic.php?id=94929 but it did not help. I am using an asus eee 900a.

Re: [SOLVED]eth0 and wlan0 do not exist

For wlan0 to appear, wireless-tools needs to be installed. Its on the cd if you dont have internet access. The only reason eth0 wouldn't exist is because there is no ethernet port. I there is, the kernel / udev is incorrectly identifying it. Not sure what to do in that case.

Right. I have wireless-tools, but right now i don't really care about it right now because i'm wired. This exact setup has worked for everything prior to the recent kernel.

Re: [SOLVED]eth0 and wlan0 do not exist

When you do: modprobe atl1e
What does this show?: dmesg
What does this show?: ifconfig

Not sure what you're looking for in dmesg, could you be a little more specific? ifconfig -a gives shows lo only.

Re: [SOLVED]eth0 and wlan0 do not exist

So lsmod now shows that atl1e is loaded?  Is dmesg now showing that eth0 (or eth1, etc.) was enumerated?  (dmesg | grep eth)  If so, what happens when you run 'ifconfig eth0 up' ? (or eth1, etc.)

lsmod does show atl1e is loaded. dmesg has no eth. ifconfig eth0 up gives

eth0: unknown interface: No such device

Re: [SOLVED]eth0 and wlan0 do not exist

soloport, and anyone else who's thinking of helping you, would like to see the messages displayed by dmesg immediately after atl1e is loaded.

Re: [SOLVED]eth0 and wlan0 do not exist

What's the output to the following? lspci | grep -i eth
Also can you dump the following? cat /proc/interrupts
What is the exact Model Number (label on bottom of laptop)?

Re: [SOLVED]eth0 and wlan0 do not exist

Try: sed -i /etc/rc.conf -e 's|^\(MODULES=[^)]*\))|\1 !eeepc+laptop)|'
And (important step!) reboot.

The driver should be fixed in the next kernel release.

Doing this did nothing as far as i can tell. By the way, thank you for taking the time to try and help me out.

How do things behave when you reboot, stop grub's default action and select Arch Linux Fallback ?

Re: [SOLVED]eth0 and wlan0 do not exist

When I reboot everything acts normal except starting network immediately fails saying eth0 unknown device. Same with Arch Linux Fallback.

Re: [SOLVED]eth0 and wlan0 do not exist

Are you able to burn CD-ROM or thumb drive and try, say, Ubuntu, Fedora or Knoppix Live CD?  (Once in a while a PHY will go dark -- i.e. HW issue.)
Have you poked around in BIOS setup?  Is it possible to Enable/Disable the interface in the BIOS?

Re: [SOLVED]eth0 and wlan0 do not exist

If i install the previous release of arch and tell pacman to ignore kernel26 and update it and it works just fine. However as soon as i update the kernel eth0 disappears. I've been using arch on this netbook for over a year.

Re: [SOLVED]eth0 and wlan0 do not exist

Ok i've solved my problem by downloading the latest kernel26 http://www.archlinux.org/packages/core/i686/kernel26/ (for i686) along with the dependencies and manually installing them using the "pacman -U kernel26-2.6.34-2-i686.pkg.tar.xz" and doing the same for the dependencies first.
