I have 3 computers on a small LAN at home. They are connected to a Linksys 4 port Cable/DSL Router. For a couple years I have used a FTP server (Bulletproof) on one of the computers to transfer work in progress between myself and a friend (we both work on the same projects). All of a sudden, I am getting corrupt files served from my FTP. The weird thing is that the corruption comes and goes. Sometimes it happens, sometimes it does not. It does not matter what FTP client is used either.
As a test, I created 4 small video files, transfered across the network via FTP using both the public and private IP, all files were corrupt. I then created an sfv file to check for crc errors after transfer. After several attempts, I was able to transfer all 4 files and the sfv file did not detect any errors, yet when I went to unzip, corruption was found.
Only FTP transfers are affected. Transfer through HTTP, network shares, etc are all ok with no corruption.
Here is what I have tried so far:
- upgraded to the latest firmware for the Linksys
- installed BlackMoon FTP on another computer, which seemed to transfer without corruption for a few days, but now it is corrupting files
- changed cables/nics
I am at a lose as to what is happening here. Any help or insight would be appreciated
