This maybe what you see after you have selected the Network Preference Pane. What is actually shown to you is dependent on what you used in the second drop down last time you were here. Mine shows the list of active or inactive Networks (mine has got several turned off in the "Network" Port Configuration" found in that second drop down)

You can use the second drop down to select your connection method (mine will list Built-in Ethernet: see next pic), but double clicking on the item in the list also works.
