I have had the same problem for about 6 months but has now gotten worse to where a reboot doesn't always solve the problem. At first I thought the problem was Roon related but the MA app doesn't connect either.

Element X will disappear off the network at times and never come back till a 30sec unplug hard reboot (sometimes but not always). When this happens, the symptoms:
1) Element X occasionally (not always) loses the SSID and IP Address (all other network devices are fine)
2) Roon cannot connect or see the device in RoonReady (and sometimes in any incarnation AirPlay, ShairportSync)
3) MA App cannot see/find the Element X (Device is Offline) even though it's clearly on
4) WiFi Configuration cannot be setup (pressing knob for 5 sec under Network Setting)
