Several networking problems after update

My set-up:

Powernode 2i (PATRATOR) wired connection

Powernode 2i (NOVASTAR) WiFi connection

2x Flex 2i with WiFi connection

=====

This system was working almost flawlessly (some glitches aside). I could connect any source to the main system (PARTRATOR) and let all others join in for sound everywhere in my home.

Two days ago I was notified of an update of the BlueSound system. I was connected to the NOVASTAR unit at that time. Late at night so I went to bed thinking tomorrow it will be all done. But the next day the PATRATOR unit was no longer visible in the app. I could connect through Bluetooth but no other way. The last source it was playing was Bluetooth since there is no SOUNDCLOUD integration!

I restarted PARTRATOR (not visible) and after that the router of my network just to make sure connections would be fresh. Still not visible. I performed a factory reset but was still unable to connect to it. I unplugged it and used WiFi for connection. Now the unit is visible again.

Current remaining problems:
- no wired connection is possible, if i plug it in again it's gone (lights are blue). Lights flash like normal ethernet connections, colour is blinking orange after a while.
- multi-room audio playing fails, i can't connect two players anymore. Not from PATRATOR but also not from NOVASTAR. Empty error messages or messages about not being able to connect appear. I have played with NOVASTAR and the FLEX 2i units before without PATRATOR, this worked fine before the update (it should not be the limitations of my router at this point).
- annoyingly the alarm function is not working anymore. I was used to waking up to my favorite tunes but it does not start at the desired time.  Also on the settings-screen it will say "Alarm on Monday 06:45 ..." even if I change the schedule without Mondays. Not a networking issue but not going to open a separate post for it.

Hopefully anyone has some insights into this? I have a party at my place on Sunday and was hoping to show off the system to the many SONOS users that exist among my friends..

Thanks!
