Install El Repo
yum install nano kmod-e1000e && sudo nano /etc/modprobe.conf && reboot
Need to download the RPM? I realize now that in my first trial, I had one nic missing, but another that worked, but installing via YUM is hard without internet, what I did the second time I ran into this was create an ISO then load that into VM and mount it and install drivers....
