I have installed Linux CentOS 5.5.  During installation, I configured the LAN driver and gave it an IP address. After installation, I checked the network connection but it shows not connected. I then tried to enable dhcp (from broadband) but system-config-network shows  Determining IP information for eth0... failed; no link present. Check cable I checked the cable and everything is OK with it. I then addedcheck_link_down(){return 1;}to /etc/sysconfig/network-scripts/ifcfg-eth0 but system-config-network still shows the same message.I have checked service NetworkManager status and service network status all is fine but I still can't connect to the network.
