Same here. AU 6.3 will not find my Time Capsule or Expresses. I still have a green light on Internet, and connect just fine. The updated AU works from my iOs devices, however.Be careful about AU 6.3. It could not find my AEBS, at least in its main window. I could configure it by going to File/Configure and entering the IP and password, but it just spun its wheel looking for it on the main window.
