I am newbie and I got first Time Capsule. Current version. I am trying add it to existing network but I can't seem to. I not sure if plug in WAN or LAN in Time Capsule? I open Airport Utility and pick "Other Options" button and give list of option. I want use "Add to an existing network" then press next. It always come back to "This AirPort Time Capsule will create a network". I thought it should give me drop down pick current network I want to add existing network. That what online guide seem tell me. Like this one: http://pinoyitsolution.com/2013/12/...g-network-on-osx-10-9-mavericks/#.WBtd8necaV4 I don't know what wrong here???
