I own both Airport Extreme and Airport Express. when using either of these wireless routers my computer cant stream video or audio on Realplayer 11 or 10. the problem happens when Realplayer is operating 1. however, when streaming through the web browser video and audio works fine. i have checked changing and opening all ports in the router, but nothing works. i even tried changing Realplayer preferences to use the web browser port 8080, but the problem still occurs. from what i understand this is a hardware compatibility issue. can anyone confirm if the this problem occurs also when using Time Capsule?
