+It could be that the network driver that is needed is not loaded.
+<WRAP info>
+**NOTE:**  Some drivers, such as **if_igb** is nowadays compiled into the kernel, so not needed as a module, so this will not appear in the list.
+So even if the driver is not seen, this does not necessarily mean this is the problem.
