Pluto: no connection to any Ethernet adapter

Hello OMs,
after deciding to update my well working Pluto to Perseverance 0303 I got some trouble with it.
After short DVB operation the Pluto cannot be connected over the network although Ethernet adapter LED is blinking and Pluto is visible in client list of the Fritzbox.
I tried a lot but nothing helps. Therefore I decided to downgrade to F5OEO Firmware which worked before. But this failed because of unknown causes.
After that tried to build up Pluto from zero in DFU mode. With USB connection Pluto is accessable via Putty and via browser (192.168.2.1).
But if I'm trying to connect with Ethernet adapter (several Linksys which are well working with my other Pluto) nothing happens. Adapter LED keeps dark and Pluto is not arrivable.
It would be great, if anybody would have an idea to resolve this issue.
