Background: I am considering an Airport Express (AE) to my room, but I am getting confusing information about how it can operate in different circumstances. I already have a router, with WiFi and LAN ports. The AE would be connected by cable to currently owned router and I would also like to connect my Mac by wire to the AE.
Question: What I want to do is extend WiFi signal in our flat and also have the possibility to use my speakers wirelessly. Is it possible with the current AE?
