Wired ethernet not getting detected

Hello Everyone,

I have installed CentOS 5.11-x86_64 on my Lenovo T420 laptop. I'm unable to detect my wired ethernet.

I tried following an instruction from an older CentOS 6 post (viewtopic.php?t=8023) with a similar issue and managed to get the following results.

Code: Select all

[root@localhost Desktop]# lspci -nn | grep -i net
00:19.0 Ethernet controller [0200]: Intel Corporation 82579LM Gigabit Network Connection [8086:1502] (rev 04)
03:00.0 Network controller [0280]: Intel Corporation Centrino Advanced-N 6205 [Taylor Peak] [8086:0085] (rev 34)
Is there any particular ElRepo kmod drive that I should install to get this working?

Would appreciate any help on this issue.

That card should already be supported by the e1000e driver.

Why would you install CentOS 5 now? It has 2 months of life left before all support for it ends.

I'm unable to detect my wired ethernet.
What do you mean? The interface is not available (as say eth0, or you don't get an IP address, or you can't communicate with other hosts)????
And as TrevorH said, if you're implementing a new host, just don't use C5, just don't.....

Hi all, thanks for the replies. I am using Centos 5 as a test machine to test a system which (as I understand) is also implemented in CentOS 5

TrevorH, you're right that the driver was already installed. It was a hardware issue on my end.

On a similar note, is there any particular driver I need for the wireless to work? I believe that it is using Intel Centrino 6205 as shown below. This is currently not showing up under Network Configuration.

Code: Select all

03:00.0 Network controller [0280]: Intel Corporation Centrino Advanced-N 6205 [Taylor Peak] [8086:0085] (rev 34)

That card doesn't appear to have a driver on CentOS 5. On el6 it uses iwlwifi.

Why aren't you using a VM for this purpose, instead of trying to get CentOS 5 run on a hardware too modern for it?

Thanks all. The VM is a good idea - probably what I should have done in the first place. I'll try to get this going.
