DISABLE LOOPBACK ON LINUX PC

Can anybody tell me how to disable the loopback on the fibre card in a Linux PC? The network has become inaccessible and we think that is the problem as it showing enabled now?

Thanks in advance for the help.

The NIC shows loopback enabled and he no longer has access to the network, is it because the loopback is enabled?

loopback being enabled has nothing to do with network being inaccessible. What exactly do you mean by network is inaccessible?

It's quite confusing, could you paste the output for the following commands:

"ifconfig -a"
"route -n"

And also let us know what kind of access are you trying to do.
