Need your help. Sorry if this is long 
I have a bdp 2, which has been running quite fine until recently. What happened is I replaced my router/network device at home and now none of my devices can connect to the bdp  
 If I manually push "restart network services" it briefly appears - both in the mpd program that I use (rigelian) and a web interface, but only for some 10 seconds and then disappears.. 
The BDP is plugged in ethernet port (my router app "sees" a "wired client", so I'm sure that the connection is actual in place) 
checked the IP address - both the player and the router show the same IP, but neither my MacBook nor any of the iOS devices discover the player. 
the software version is S2.42 2019-12.02
What am I doing wrong? what can I do?
Thank you!
