Recently I had to move big folders inside and to my NAS D-Link DNS-345 and often the process ends with this error. Other components are router TP-Link WR740N and PC with XP 32 bit, connected to the router trough PCI LAN-card 10/100. I use regular cat. 5 cables that the guys from my ISP kindly left me. I can't see particular pattern for this error - usually it appears while transferring 10-20 GB folder, but yesterday I tried to copy 1,7 GB folder with small files(web pages, small pictures) and again got this error . In the Event Viewer I don't see nothing related, in the log of the router also. I have Comodo IS(free) and I don't see something blocked there. How to define the source of the problem?
And second question - because the router is 100(150) Mbit - can I connect my PC with NAS with additional LAN cable directly? The integrated LAN port on the PC isn't used now and the NAS has second LAN port, but I don't know how to configure the parameters and is this possible in that way.
