eth0 not working

startover · 02-04-2011, 08:57 PM

I get

Code:

myhost dhcpcd: eth0: interface not found or invalid

during the boot and when I enter

Code:

$ ifconfig -a

eth0 does not show up in the out put.

it seems that the kernel is not seeing the ethernet chip at all.

I tried to modprobe whatever module I thought helpful, but no luck

We are going to need a lot more information to be of any use. For starters, what network hardware are we even talking about here? Is it Ethernet or WiFi? USB or onboard?

If it is built in, post the output of "lspci". If USB, then run "lsusb". Once we know what the hardware is, we can look at getting it working in the kernel.

It works now by reinstalling a newer version of kernel

Code:

$ lspci | grep Eth
02:00.0 Ethernet controller: Atheros Communications AR8151 v1.0 Gigabit Ethernet (rev c0)

newer image of Arch linux from http://releng.archlinux.org/isos/ solved the problem

Well, you could just do that too. If this problem is resolved, then mark the thread as "SOLVED" for future reference.

It would also be nice if you could post information about the hardware in question and the kernel versions involved, so that others who may have this same problem can find this thread.
