Dell Precision 3440 Ethernet Connection is not working

[tuski]

I have installed CentOS 7.9 on my Dell Precision 3440 with GUI. But the ethernet is not working. I am new to CentOS.
The current kernel version is

Code: Select all

uname -r

Code: Select all

nmcli d

What should I do to activate ethernet connection? Thanks in advance.

You need kmod-e1000e from the ELRepo yum repo along with their elrepo-release package.

As I am new to CentOS is there any blog post or youtube video regarding this?
Or could you explain a little bit more?

Google "ELRepo". They are a third party yum repo specialising in hardware support. They have an rpm package called kmod-e1000e that contains a copy of the e1000w driver that is newer than the one in the CentOS 7 kernel and supports your card. Download the kmod-e1000e package from their repo manually, copy it to the machine then yum --disablerepo=\* install /path/to/kmod-e1000e...rpm
