unable to connect to wired Ethernet

Post by sleepless cupcake » 2017/02/14 20:11:41

Hello All. I just recently joined the Linux community due to work, and my boss has me building a CentOS machine for him so he can run a particular program. For it he needed me to create the system as a CentOS 6.5. I successfully managed to install the OS, but now I can't connect it to the internet. I have an ethernet cable plugged into the back of the computer, but when I type "ifconfig -a" into the terminal, all I get is

lo. Link encap:Local Loopback

There is no eth0 despite it being hardwired into the back of the machine.
When I run "lspci -nn | grep -I net" I get:

00:1f.6 Ethernet controller [0200]: Intel Corporation Device [8086:15b7] (rev31)

I have downloaded and run the rpm for kmod-atl1e and it didn't work to make the computer recognize the ethernet I had wired into it. Please let me know if there is any more information you need from me to help me solve this problem on my computer!

As far as the driver is concerned, it [8086:15b7] is supported by the e1000e driver which is part of the kernel. So there is no need to install any kmod.

Were you able to configure the network with no apparent issue?

I cannot configure the network at all. It is not registering that there are any networks connecting to the computer. When I try to go through the reinstall process, the configure network button is greyed out and unable to be clicked and the program version of configure network doesn't download.

Not sure if it helps, but I am installing the OS on a Dell Precision Tower 3620
