Extend Airport Extreme Network via Ethernet to Airport Express
I have an Airport Extreme and recently purchased 2 Airport Express units (the new ones that sit on the table top). I was successful extending the network wirelessly but as soon as I introduce the Ethernet Cable (using the Airport units for Audio speakers so want to extend via ethernet) I continue to get the same problem when setting them up "Unexpected Error...Try Again". I cannot figure out where I am going wrong.
Can someone please give me "dummy" instructions on how to extend the network via Ethernet. I want to create multiple "Airport Express" zones that are hard wired via Ethernet. Any insight or direction would be appreciated.
Thank you.
