I’m sending Shure a Netgear Prosafe JGS516PE. They’re going to run it through a bunch of tests to see what is causing the issue. I’ve found that all Shure devices except the clock master fall off the network every 5 minutes or so. My guess is it’s a protocol that Shure uses for control that’s causing the switch to block ports. If it was QOS it would effect all the devices including non-Shure items and only cause an audio drop out, not network loss. I’ll keep you all in the loop as I hear back from them.
