Thanks!, I ended up getting it working, but not sure what I did that made it work. There was a Netgear unmanaged switch plugged into the TP-Link router in with the mixer was plugged into. I removed that and isolated the two Ethernet connected devices to ports two and three of the router. Still worked on wired and not on wireless. I then moved the port the mixer was plugged into to port one and it started working. I may have done something else, but nothing of any significance. Going to see how things are working over the next few days, but still scratching my head about what actually fixed the issue.
