Wired ethernet not getting detected

philo_ · Post by **philo_** » 2012/04/26 22:00:55

Hello Everyone,

I have installed CentOS 6.2-x86 on my Lenovo Z465 laptop.

[b]I'm unable to detect my wired ethernet.[/b]

I tried searching for it extensively but I think I was unable to make sense out of the posts already present.

I know this has something to do with the need to install the correct drivers.

Also posting the output of few popular commands which I'm sure I would be asked to execute.

==========================================
[b]sudo ifconfig -a[/b]

Output :
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1
...........
...........

No other interfaces were detected apart from loopback.
================================================
[b]lspci[/b]

Output :
...........
...........
02:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)
03:00.0 Ethernet controller: Atheros Communication Inc. AR8152 v1.1 Fast Ethernet (rev c1)
=================================================
[b]ifup eth0[/b]

Output :
/sbin/ifup: configuration for eth0 not found
=================================================
Please let me know if you need any more information.

Looking forward to some pointers on this issue.

Welcome to the [i]CentOS[/i] fora.

You were [i]so near[/i] to providing the necessary information . . . if only you had posted the output returned by executing the following, we would then be able to advise you! :-)

[code]
[b]lspci -nn | grep -i net[/b]
[/code]

# lspci -nn | grep -i net

I'm glad to hear your reply.

Use the link to ELRepo in Alan's sig and you'll find a driver there for 1969:2060. You want kmod-atl1e.

Thanks ~~~
The wired network is running now,
via the driver kmod-atl1e.

but ,how about the wireless one?

Unluckily, The wireless one doesn't work still.

Did you try kmod-compat-wireless? What exactly are the symptoms of "does not work"?

Hi All, this is my first time installing CentOS on a development server at work. CentOS installed successful however the wired network connections are disconnected.
I ran the following commands:

lspci -nn | grep -i net
00:19.0 Ethernet controller [0200]: Intel Corporation Ethernet Connection I217-LM [8086:153a] (rev 05)
03:00.0 Ethernet controller [0200]: Intel Corporation I210 Gigabit Network Connection [8086:1533] (rev 03)

ifup eth0
/sbin/ifup: configuration for eth0 not found.

Any suggestion would be greatly appreciated. Thanks!

Please don't hijack old threads and reuse them. Start a new thread and refer to the old one if you think it's relevant. This thread is now locked.

Both of those PCI vendor:device ID pairings should be supported by CentOS 6.4, the i217 by the e1000e module and the i210 by the igb module. If you didn't install CentOS 6.4 then you should do so! If you've done extensive customisation of the system already then you could probably run a `yum --enablerepo=c6-media update` with the 6.4 DVD ISO media mounted on one of the three locations mentioned in /etc/yum.repos.d/CentOS-Media.repo but otherwise it's probably easier just to reinstall. If you are already running CentOS 6.4 then mention that in the new thread you create.
