I have problems with my network connection eth0 I created /ifcfg-eth0 file since it was not present at /network-scripts. I tried ifconfig which does not display eth0. I have wlan0 which gets connected at ease.

I have checked service NetworkManager status and service network status all is fine.

I also ran:

$ lspci | grep -i net
03:00.0 Ethernet Controller: Qualcomm Atheros QCA8171 Gigabit Ethernet(rev 10)

  • Did you actually create /ifcfg-eth0? What's /network-scripts? Do you mean /etc/network-scripts or similar? What are the contents of this file you created? Are you connecting over wireless or ethernet? What kind of hardware? Can we see the output of ifconfig? Basically, we need a lot more detail than this.

  • Is your network interface visible if you do sudo lspci|grep net?

  • Is it possible that CentOS uses another naming convention for Ethernet interfaces? My Fedora installation calls the Ethernet interface p5p1 whereas my Debian installation calls it eth0 (same interface).

  • @terdon /etc/sysconfig/network-scripts/ifcfg-eth0 was created by since it was not present
