I am trying to connect communication between 2 buildings. In the main building, I have a Cisco aironet 1100 connected to the wired Lan. In the other building I am trying to install a Cisco 1242AG. I am in the setup interface of the 1242Ag under the section where I need to choose the role of the 1242AG. The 1242AG will need to communicate wirelessly with the 1100 AP and will be connected to a switch inside of the building. What role should i choose?
