Take an existing wireless network and create your own

[apatel87]

Hi I have a general wireless network as part of my apartment complex that is shared over the entire apartment complex. It works well independently with my separate devices but I have a NAS that I would like to get on my own network and my computer and iOS device does not see my Apple TV on the same network even though it is for Airplay. I have an Airport Extreme and I want to capture the current wireless signal and create my own network. This will allow me to connect my NAS to my devices and allow me to Airplay. I can extend a network but I do not think this is the same as creating my own network. Thanks! Any help would be much appreciated.
