I didn't get a connection with the web interface anymore after changing from the Ronaldd image to the Gemini image. Furthermore I could not mount the Dreambox by means of \\DREAMBOX on a PC.
I just found the problem: after installing the SAMBA server everything works OK. The link to \\DREAMBOX was not valid anymore however. It seams that I now have to link to \\DREAMBOX\harddisk.
It took me the whole day to find out . As always: Just after asking support from other users you find the right way yourself!
