IPKG online installer not connecting to internet

  • Hi,
    I have a DM7020HD receiver using Newnigma2 software. My problem is that when I try to upgrade my system or manage Plugins the IPKG installer shows the message "Your dreambox isn't connected to the internet proprly" I have reset the system and check that the internet is connected by using the DM's browser. This wrks OK. the installer still displays the same message. The DM bo is connected to the Router via an ethernet cable.
    Can anyone help please.
