From the URL below, I found new firmware below released last December 2015
http://tsd.dlink.com.tw/
In its release notes, the following are indicated
Problems Resolved: New firmware adopting mydlink service change, all previous version will now incapable of using mydlink service.
Known issue: Router performance may be impacted if massive (over 10,000) quantity of media files existed in the connected USB drive
1. In the problem resolved, does it mean that mydlink registration using F/W 1.05 release won't be possible?
2. In the known issue, will the files in HDD connected in USB port be deleted or USB drive connection won't be possible?
Any ideas on these?
