I am trying to copy a large folder (my music) from my Windows 7 machine to a Windows 8 machine via a LAN. Inevitably, once robocopy is run, the state of the network will start fluctuating between connected and disconnecting for the W7 machine. The disconnects happen every 20-40s without an apparent pattern and the network reconnects immediately.
Here is my robocopy command line:
robocopy "D:\copyfrom" "\\W8\Share\copyto" *.* /Z /MIR /mt /R:100 /W:30 /XF *.ini
My D drive is an external hard drive, but I have the same problem when copying from my internal drive as well.
The W7 machine is connected via ethernet and the W8 machine is connected via wifi.
I have tried adding a /TBD to the command line, but with no particular effect except that it may increase the delays between disconnects slightly.
I have tried disabling Remote Differential Compression and Auto-tuning (this helped once when trying to improve network copy speeds), but have re-enabled them as this has no effect.
EDIT: The problem was solved by changing the connection to a different port on the switch.
