I have Samba installed on a Kingstom MLWG2. The storage media is a 64gb sd card formatted FAT32 for compatibility with Windows Explorer. I am running on Windows Vista 64 bit. I am unable to copy a file greater than about 710MB from the client to the router over Ethernet. I get an error that points back to an issue with the file. I can move, in one go, individual files totaling more than this amount (820MB tested). I can copy a file from the media that is larger than than 710MB (1.7GB tested). There is plenty of empty space.
There is a problem accessing [filename].
Make sure you are connected to the network and try again.
The Kingston is a MT7620N based device (580mhz) with 16MB flash and 64MB ram.
While I am pointing at Samba, I am not clear this is the problem.
Any ideas of what might need freshening up?
