Hi all, I have an AirPort Extreme Base Station (5th Generation) providing me with a Wi-Fi network. I have: an iMac connected via ethernet to the AirPort Extreme an AirPort Express wirelessly joining the network for AirPlay an AirPort Express (A) wirelessly extending the network an AirPort Express (B) wirelessly joining the network beyond the extended Express for AirPlay Now, whenever I sit between the AirPort Express (A) that extends the network and the Express that I use for AirPlay (B) there is no internet. There is a connection because my CloudApp and Adium connect but I cannot load any pages in Safari or Chrome, or send any IM messages. I can use AirPlay fine. There's no issue with packet loss or the likes. It's very strange. I've tried to reset the AirPort Express and even reconfigure it, reset the Extreme and nothing seems to work. Anyone have any ideas?
