On one end of my apartment, I have my Airport Extreme (living room). On the other end, I have an Airport Express connected via Ethernet to the Extreme & extending the network (in the bedroom, as an access point). We have it this way because reception is very bad from one end of the apartment to the other. For some reason, when in my living room, Macbook Pro Retina connects to the access point in the bedroom, and internet speeds drop very badly. I verified this in Airport Utility - the Express is showing that my MBP is connected, while my other devices are simply connected to the closest access point. This problem persists after restart, resetting the PRAM, etc. What can I do?
