Webpresenter HD ethernet not working

When ethernet cable is connected to the ethernet port no Ethernet icon is displayed on the LCD screen, only text OK is displayed and streming is not working. The lights on the ethernet connector are not lit, neither on the router end (I have tested many cables, same result). I have also tested with DHCP an Static. The same result.
The only time ethernet lights on Webpresenter are lit is when it just booted up (1 sec).
However when a phone is connected a Smrtphone icon is displayed and streaming is working ok.
Have installed the latest 3.5 firmware.
Did the "Factory reset" from the Setup app. Did not help..
And as a side note: What is the point not letting the user to set stream key / pass pharse etc with Web Presenter itself??
