No eth0 interface
 

There's no wired interface. Wireless is working fine. Ubuntu 10.04. (Can't go more recent than that, because the Intel wireless driver won't work in newer versions.)
lshw contains the following:
I added the last two lines in this next bit. First used eth0, then eth1.

Hi,

What does this command tell you?

and this one:
Also, what is your hardware (make/model)?

Run in terminal
Now it shows your current using 'eth'

Enable this eth,(Suppose it is eth4)

nugat,

This is a Sony VAIO Model PCG61A14L.

pavi_kanetkar,

The output of ifconfig -a is in my first post. There is no eth device shown.

Thanks for your help. (Background--I first installed Mint Cinnamon 13, where wired, eth0, was working but no wireless. There's a thread over in the Laptops forum about that. Trying SUSE and Fedora disks I had from a recent conference, with many suggestions I got from that forum, I eventually had to go back to this Ubuntu 10.04 version to get wireless to work. Now I have wireless but not wired with this version, which overall would be my preference if I can only have one. But I'm trying to get both working.)

Seems to lead you to some links that may help here. http://www.linuxquestions.org/questi...1083-a-930325/

Thanks for the link. I read through that thread and tried some of the suggestions. It ends with someone saying they solved it, but not telling how!

I get the same response below from both 'networking restart' and 'ifup eth0'
I mentioned that I had also installed Mint Cinnamon 13, where I had wired but no wireless. I went to that installation, looked at /etc/udev/rules.d/70-persistent-net.rules, and copied this into my Ubuntu 10.04:

I'm going to reboot to see if this does anything, so I need to post what I've accumulated here or lose it.

Thanks again for suggestions.

According to this, that Atheros chip is supported by Linux kernels >= 2.6.38, which is probably more recent than a 10.04 kernel. Is that so? You can try getting a more recent kernel via PPA sources described here.

Or you could just download a more recent version of Ubuntu, run it in Live mode, and see if the Atheros NIC works. That would tell you if the kernel driver is the culprit.

Can you please post output of
dmesg | grep 'eth'

Method -II
**********
Run following commands

modprobe -r tg3
modprobe broadcom
modprobe tg3
ifconfig

So if the chip is supported at 2.6.38, I'm just a little behind. The thing is that I know my Intel wireless device stops working somewhere between 10.04 and 12.04. Maybe 10.10 is my sweet spot?

The dmesg command returns nothing, . I thought I had posted that earlier, but don't see it.

that would suck. but maybe if you try an updated kernel, just to see if the Atheros Chip works, maybe you'll get lucky with the wireless, too?

The instructions were:

To install kernel 2.6.38:

sudo add-apt-repository ppa:kernel-ppa/ppa
sudo apt-get update
sudo apt-get install linux-headers-2.6.38-1-generic linux-image-2.6.38-1-generic

I ended up with: E: Couldn't find package linux-headers-2.6.38-1-generic

See anything wrong with what I did here?

It looks like that kernel has been removed from kernel-ppa:

http://www.ubuntuupdates.org/package...aders-2.6.38-1

but there is a 3.x kernel available, I think. you could always try that. do a search for them, e.g.:

that gave me a list of linux-image and linux-header packages. i picked the latest one and installed with:
