When I work with a large number of files (copy, delete) on a remote FTP server, WinSCP stops with an error "Lost Connection. Timeout detected." after some time. Fewer files are always copied correctly, no matter what size they are. But if I copy something like all folders of a phpbb installation at once, it seem to fail. WinSCP processes some files, and then it gives this error. I tried other client (CuteFTP) - its behavior was slightly different, but I still got an error stating there's no connection to the server in the middle of copying the files.
The complete WinSCP log is located here: <invalid hyperlink removed by admin>
I thought the issue is related to the FTP server itself. So I asked my friend to do the same operation (copy / delete the same set of files to the same server) from his location (he uses a different ISP) - and it worked fine for him, without any issues.
I don't think it's my ISP that is causing this. I tend to blame my system, or my home router (LinkSys RV-042). But I can't figure out what's exactly wrong with my setup. Could you please help me to track this issue and find a work around?
Using Passive mode doesn't change the situation. I get some (many) files copied, and then the following error appears:
