+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.
+</WRAP>
+----
+===== Load Drivers =====
+Try the following drivers:
+  * igp
+  * em
+----
+===== Try load em driver =====
+Load the **em** driver as a module at boot time by placing the following line in **/boot/loader.conf**.
+<file bash>
+if_em_load="YES"
+</file>
+<WRAP info>
+**NOTE:**  There are other tunables too.
+See https://www.freebsd.org/cgi/man.cgi?query=em&sektion=4
+</WRAP>
+Then reboot and see if that makes a difference.
+----
+===== Try load intel igp driver =====
+It may be that the **igp** driver is not loaded.
+The **igb** driver supports Gigabit Ethernet adapters based on the Intel 82575 and 82576 controller chips:
+  * Intel Gigabit ET Dual Port Server Adapter (82576)
+  * Intel Gigabit VT Quad Port Server Adapter (82575)
+  * Intel Single, Dual and Quad Gigabit Ethernet Controller (82580)
+  * Intel i210 and i211 Gigabit Ethernet Controller
+  * Intel i350 and i354 Gigabit Ethernet Controller
+<WRAP important>
+**WARNING:**  The **igb** driver is often complied into the FreeNAS kernel so these next steps might not work.
+If this does not work then just comment out the loading of the "igp" driver within **/boot/loader.conf** file.
+</WRAP>
+Place the following line in **/boot/loader.conf**:
+<file bash /boot/loader.conf>
+if_igb_load="YES"
+</file>
+<WRAP info>
+**NOTE:**  There are other tunables too.
+See https://www.freebsd.org/cgi/man.cgi?igb(4)
+</WRAP>
+<WRAP info>
+**NOTE:**  You might need to reboot to be certain the driver is loaded.
+You could also try to load it manually:
+<code bash>
+kldload if_igb
+</code>
+Check if the driver is loaded
+<code bash>
+kldstat

+kldstat reports that **if_igb** isn't loaded, so it must be compiled in.
