See the screen capture of the networks on my mac below from system preferences: Can someone help me identify where all these networks came from and what they could be? If you see in the screen capture of the network tab of system preferences, I have four different ethernet connections? I am on a LAN but why would that require three different connections to be active (the ones in green). What are they all there for? I am just curious to learn really, there is no problem as such. I am just confused as to why I have so many connections that I don't seem to use. When I am at home I use the airport only. Can I just delete the others?
