I have a new install of CentOS 6.4 on an HP Pavilion 500-27c with one mother board nic card. results of lspci : 01:00.0 Ethernet controller: Atheros Communications Inc. AR8161 Gigabit Ethernet (rev 10) 04:00.0 Network controller: Ralink corp. Device 539b results of ifconfig -a lo Link encap:Local Loopback wlan0 Link encap:Ethernet HWaddr 70:18:8B:80:AE:71 There is no /etc/sysconfig/network file present. The install was performed without incident from a DVD. I would surely appreciate your help in trying to activate this network. Is this a problem with the 6.4 disc or do I have a network card on this machine that is not supported by 6.4 -- Greg Ennis PoMec Corporation www.PoMec.Net
