Cannot find eth0 in ifconfig

dipankar · 2013-10-04 13:38:14

Hi friends,

I have installed crunchbang on my lenovo g400s laptop. But I cannot connect to the wired network. ifconfig shows no eth0.

I am running Linux Mint in parallel. Here everything is fine eth0 is detected automatically. Have I done anything wrong during installation?

^ try

$ ifconfig -a

Maybe, it will show your eth0 ...

Also, in connection manager, check if 'Connect automatically' checkbox is checked for your particular wired connection.

I have tried that .. but still cannot find it. When I edit my wired connection I find the entry device mac address blank. Stll waiting for a solution ..

Well, next what you can check is

$ lspci -v | grep -i Ether # I show my output
09:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8040
PCI-E Fast Ethernet Controller (rev 12)

to see if your network card is recognized.

Here is my output

Maybe your download was faulty, check its md5sum.

I have installed crunchbang from the same source on a different machine and it's running fine, no ethernet problem. The problem might be with the lenovo g400s model. I have searched for it .. seems like something called alx driver have to be installed. But I cannot figure a way out.

maybe this (yet another atheros ethernet issue (solved, just fyi post)) will help you‽

dipankar · 2013-10-08 08:33:52

Visited the above link posted by shem. Followed the steps. When I run "sudo make defconfig-alx" I get the following error

can't find file Kconfig
make[1]: *** Error 1
make: *** Error 2

My kernel version is the same as in the link posted by shem. The output of "uname -r" is 3.2.0-4-amd64

Any ideas?

Hi dipankar and welcome to the forum! I've moved this to Help & Support (Stable).

Maybe this will help :-

I apologize for resurrecting an old thread, but I didn't want to clutter the board with the same question.

I don't see that this was ever solved, but I have the exact same problem that dipankar has. I have no eth0 interface, even when doing ifconfig -a. Wireless works fine though.

My lspci -v | grep Ether output is the exact same thing he has too:

03:00.0 Ethernet controller: Atheros Communications Inc. Device 10a0 (rev 10)

Does anyone happen to have any input?
