+===== Force the speed of the network cards and set the Duplex mode =====
+Navigate to **Interfaces -> LAN**.  This is the Physical Interface.
+  * Speed and Duplex:  **Select the desired speed and duplex from the drop-down menu**.
+  * Click **Save**
+  * Click **Apply Changes**.
+Natigate to **Status -> Interfaces** and check the Media line for the interface in question.
+If the selected speed and duplex are listed, then the setting has been applied as expected.
+----
+===== Switch back to autoselect =====
+To switch back to autoselect, use the same settings and select **Default** under **Speed and Duplex**.
+<WRAP info>
+**NOTE:**  Some network cards do not support manually configuring their speed and duplex.
+Notably, this is an issue with many Realtek cards, including network interfaces which utilize the re(4) driver.
+The settings appear to apply, but the card remains in a duplex mismatch state.
+In these cases you can work around the problem with a small managed switch.
+Set the speed and duplex of one port to match the upstream, and then set the port facing the affected NIC to autoselect/autonegotiate.
