So you have BomeBox WiFi as an access point on network 192.168.153.x and ethernet on network 192.168.1.x ? In that case, your BomeBox is set up as a router and according to what I read, should work. I’m not that familiar with QU-Pad to know how to configure it and not sure how Qu-16 handles multiple connections. I think you might want to ask Allen & Heath as they commissioned Bome to build the BomeBox interface. I know it uses TCP packets and with my A&H simulator (not a real device), I can send from multiple locations just fine. The best way to find out other than that would be just to give it a try.
