I have a Time Capusle in my basement connected to my internet model. It's connected via wire to some home theatre products (the reason it's in the basement) and then putting out it's wireless network for my laptops. I also have an Airport Express. I would like to put the AE upstairs and extend the network, so I have a little more signal up there. It is NOT possible for me to hardwire the AE into my TC. So I have two options. 1. Can the AE accept the TC wifi network AND extend it without using ethernet in any way? 2. I can use ethernet to connect the AE directly to the model. In my mind, that creates two competing networks, one from the TC, one from the AE. Any way to merge and extend that way? Any help would be appreciated.
