Debugging failed audio packets

[tups]

I know from my own experience that the Airport Extreme is not a good choice for Jamkazam. It's obsolete and should not be used for security reasons. You would have better results with a modern router that will allow you to configure port forwarding.

AFAIK the Virgin Media hub is a wireless 4G device, similar to using a cell phone? Or is that a wired WAN modem?

Thank you for the thoughts. The super hub is my main virgin modem/router coming in so I'm using it in wired WAN mode. I've tried it with the Airport just being an access point / switch rather than router, with the virgin box as the router, but will trial taking the apple box out of the loop completely. It's a tricky one that it only fails some of the time!
