Here's the basics of my current set up. One 802.11 Draft N Airport Express (first revision, 2008 model) creating a wifi network, connected to living room stereo for AirPlay. Currently set to 802.11n (b/g compatible). One 802.11 b/g AirPort Express (original) in the other room joining the network in bridge mode with another pair of connected speakers. I've got two problems. The first is that I get significantly slower transfer speeds between my MacBook Pro and the Mac mini in the living room when the MBP is in the bedroom, and my apartment is not very large. The second problem is that when AirPlay streaming audio to either one APX or the other, or to both at once, I get frequent dropouts and interruptions to the music. This occurs far more often than it ever used to when I was just streaming to the old APX. Is there anything that I can do to increase the wifi signal to the bedroom or to eliminate AirPlay dropouts without having to buy new hardware? Would buying a new APX even help?
