I'm not experienced with your setup, but I would ask at Centos help
boards. Also of course check cables, e.g. try a laptop on the same
network cable.

> My OS is Centos 6.7, and the version of Network manager is Applet 0.8.1. When clinking the Network manager icon at the upper right conner at the Desktop of my compuer, I can see in the pop-up manu that there are two network cards (Intel 82573E Gigabit Ethernet Controller (Copper) and Intel 82573L Gigabit Ethernet Controller) but only one link (System eth1) available. Usually when clicking the "System eth1" the Internet connection would be established. However from the last morning clicking the "System eth1" only gives connect "nectwork connectiong has been disconnected" information.
