Does anyone have a digital system that is as involving as their analogue front end?

@audio-b-dog , sounds like you may have solved your problem by making sure the Meitner and JPlay are all on the stronger network, and I don’t know your network topology (obviously), but let me ask if you have an extender (as opposed to a full Access Point/Mesh unit) in your network?  

I was having similar problems with TIDAL and Qobuz (via Roon) to what you report and after much trial and error and tech help from Innuos, Roon and BlueSound, it seems that my problem was being caused by a WiFi extender unit (WiFi 6) where all my WiFi Access Points are WiFi 7 (all components in the network are Ubiquiti). I was told that extender units are known for causing problems with data transmission and renderer connectivity (in your case the Meitner). So, if you have an extender you might want to replace it with a real AP/mesh component of the same generation as your WiFi router.  (I replaced my WiFi 6 extender with a WiFi 7 AP and all the problems went away. 

(BTW, It turns out the extender was also causing the problem that i posted about a week or so ago about my Innuos Stream1 not being discoverable on my iPad via the Sense app or directly via its IP address, even though my iPhone never had any issue discovering and controlling the Stream1.)

I have it plugged into a mesh component. The other mesh component across the room is connected to ATT fiber. We have an old wifi name from before we put in fiber. We found out that the ATT fiber offered another wifi name which seems to be stronger than our old name. I rebooted the network but now the Meitner is not connected to the iPad. I had this happen with my Moon and had to call Moon. Everything has to be turned off and then on in a certain order. I haven’t found that order yet, so Jplay is not connected to the Meitner. I’ll try again tomorrow when I have a fresh brain. I even deleted Jplay and reloaded it. Later I’ll try asking chatgpt. Sometimes it actually knows and other times it just gives me BS. I’m playing a CD through the Meitner now. When it gets going, I think that putting the iPad on ATT’s wifi name might very probably fix the problem. Thanks for your input.

You need to switch the ipad to the same wifi your Meitner is connected to. The controller and the streamer have to be on the same network for it all to work.

We only have one network and the Meitner is hardwired with ethernet. It does not operate over wifi. The iPad operates on wifi to the same network. I checked bluetooth and the Meitner is not listed, but it might not talk to the iPad on bluetooth. When this happened to my Moon, the tech at Moon had me take everything off the network, shut down the Moon and reboot it, but it took him several times to do this in the right order. I'll listen to records today and call somebody tomorrow.

There is no Bluetooth there. It’s all network. 
You said you have 2 mesh nodes? Each one has a different network name?

Let’s say mesh node 1 wifi network name is dog 1. Mesh node 2 that the Meitner is hardwired to, network name is dog 2.  
Go to your ipad wifi settings, and select the network with the name that corresponds to the node that feeds the Meitner. 
You should be good to go.
