The Filezilla program does not actually solve the “Data link not established: ENETUNREACH – Unable to reach network” error. In other forums, there have been proposed methods such as passive mode active mode or only plain ftp option, but I have not tried all of them. I have a single solution and also use a different program 🙂 My recommendation is the Cuteftp program. I started using it in 2000 years. Comprehensive, more stable program than Filezilla.
