Settings to join two Airport extremes via ethernet to extend a network
I have two airport extreme routers. One in my house and one in my garage some 200 feet away They are hardwired via ethernet cable. The one in the house is set to create a wireless network. The AE in the garage is also set to create a wireless network. I have a number of POE cameras on a POE switch in the garage that I cannot seem to get online. What should my settings be on the the AE in my garage?
