There has been no changes to the router or any other networking, this just suddenly started to happen. The Audio matrix is connected to a Cisco switch which seems to be working fine for everything else, i haven't noticed any other issues with the rest of the system. If i look at the network port on the back of the audio matrix the green light is on as well as the orange light which is flashing.
I have tried a different cable between the audio matrix and the Cisco switch but it didn't make any difference.
Thanks for any help you can offer.
