Hi all, I have an Asus RT-N56U router that is currently setup in the living room. However, my desktop in the bedroom which is located in the 2nd floor is not getting good signal. Here's what I would like to do.. and was wondering if they are doable. 1. Can the airport TC be added to the current setup and extend the network coverage? 2. Is it possible to create a second network out of this? How can I be able to do this and also prevent people on the same network to access the data on my airport TC?
