Currently, I have an AirPort Extreme at one end of the house. I have a PS3 in my bedroom at the other end of the house. As the WiFi from the Extreme is pretty weak in my bedroom, I installed cat5e cable from the Extreme to my room. I'm wondering if I can use one of the new AirPort Express ethernet ports to connect to the Extreme and the other to connect to the PS3 to have awesome dual band WiFi in my room as well for my other devices (Macbook, iPhone etc). Just wanting confirmation that this would work or not.
