Enabling both isn’t quite as simple as it sounds. The problem would be that the internal DHCP server would also need to be switchable. If connecting to a network with a router or other DHCP server, it would need to be switched off, otherwise it would need to be configured to hand out IP addresses on the LAN port too. An even bigger issue would be that if you disabled DHCP for a gig, then tried connecting to the mixer’s WiFi without having a router attached to the LAN port. With no DHCP server, your device wouldn’t receive an address which would require you to manually set one in your mixer’s default IP address’s range. Suddenly the simple CQ becomes much more complex. I suppose that you could auto-detect the presence of another DHCP server then auto disable the internal server if one is found, but then there’s the issue of when you switch it off, and have already connected devices. The addresses on those devices will be wrong. The whole thing is quite messy and above many people’s knowledge level.
I believe A&H wanted to keep CQ extremely simple, and user friendly, so the above reasons are some of why it is they way that it currently is. I’m not saying that it shouldn’t be done, but it would need some other options enabled in the UI, and people would have to understand when and how those should be set.
In my opinion it is much easier to connect an external router with WiFi, and then switch the CQ to use the network port.
