en1 is your wireless connection. If you turn the wireless off, then this should go away. But if you want to connect wirelessly to the AirPort base station, then you should leave it on and set up passwords. To connect the base station to the modem, you should plug the LAN port of the modem to the WAN port of the base station. Then you can connect your Mac from one of the LAN ports on the base station and open the AirPort Admin in your Utilities folder and set it up. When choosing a password, make sure it is long and randomly pick numbers and letters so that it'll be hard to figure out, That is about all I can tell you, as I have never used an AirPort base station.
