well, I simply changed my wifi setup and AIR works 100% as well. I use a new Apple Aiport Extreme.
No matter what Router or access point I used it worked after realizing something.
I guess (hope I am right) the solution is to put the Wifi-Access-point as close as possible to the Devialet and the Audio-Server/PC.
I also defined a dedicated wifi network (e.g. devi-net) only for audio, which is connect to the other wifi networks in my house and to the Internet of course (Tidal).
With a signal strength better than -40 db (RSSI), it worked ( I have now -21 db, that is perfect!) with every router/access point without any problems. Even with 192 KHZ files....
Combined with my Roon Server (Surface 3 Pro) close to the Access-Point, I use my Ipad as a remote (having -27DB signal strenght here as well) it works smooth as it can get....
