Hello everyone, I need help, I have virtualbox installed correctly, it works almost everything, the only thing that I can not run a print server netgear; the PS121.
this is attached to a netgear router DG834GT.
the router works fine, but when I try to load the program print server did not detect anything the PS121 will do the printer.
is there any special settings to be done?

thanks to all

To be sure you are in the perfect conditions, use bridged mode on a wired connection.
