Dear all.
I'm using a LS-420D, 2 HDD 1T x 2, with the firmware 1.81, and i get the same the error. I cant start the DLNA service and receiver a message about updating DTCP-IP but i cant perform that updating, even i had tried many ways : reset NAS, format and reinstall firmware 1.81, reboot ... When i try to update DTCP-IP, i usually get a message "check internet connection" or "task not perform". The weird thing is i have no problem with my old NAS LS-410D. The NAS LS-410D works well with the firmware 1.81. Please help me to fix this error on my NAS LS-420D.
Thank you in advance.
