Disconnections when transfering files

I have the MyBook Live 3TB connected via ethernet cable to the Drytek 2710n router and wirelessly connected to my PC (Win 7). I have following issues:

-When transferring a large file from my computer to the WD after some time the transferring stops and a dialog box appears saying that cannot find the specified file on Z: WD location…

-When I download a file with a torrent client directly to the WD after a while (it depends, maybe 10 min, maybe 5 hours etc) the connection get lost again… I resume the torrent and after a while again gets lost.

I have eset smart security

Any idea? Thx 

Nothing with this, no ideas??? Please!!! :slight_smile:
