CentOS 7 not showing wired connection as well as server not found at firefox

[Ekta Banik]

Not yet but about to install. What after that ? Kindly let me know

Unable to install with the command
Sudo yum install kmod-e1000

Not surprising if you don't have a network connection:
Download it on another machine, transfer it and then use rpm to install it.
And if you have network, first install ELRepo.

if you have network, first install ELRepo.

I.e. run: yum install elrepo-release

use rpm to install it

Use yum. When you have the RPM-file, run: yum install kmod-e1000e*.rpm
(If yum does not like the lack of network connection, then yum --disablerepo=* install kmod-e1000e*.rpm)
