Re: Unable to detect LAN of RHEL 5.5 on Dell Laptop.2011-12-02T16:36:45ZThis is the accepted answer. This is the accepted answer.Have you resolved this issue? lo is the "loopback" network, which the system uses to talk to itself. It will always be present. If you type ifconfig as root what output do you receive? You have probably already checked this, but sometimes a network card will be disabled in the BIOS. You should be sure that the NIC is not deactivated. (You laugh, but I've done that!)
It could be a firmware issue. Obviously, and IBM site is going to have less information available for a Dell product, but here is a thread, "(SOLVED)No network interfaces on Dell Inspiron 14R N4010" which might have some useful information.
If you find the solution, please post it back here so others can learn from it.
