FTP will not connect with T-Mobile home internet???

[wdgay]

FTP connects with DSL but will not connect with T-Mobile home.

Do you have a different firewall with that router that could be interfering?  That is where I would start. Also if you click on Site-->Advanced-->FTP Log next time you try to connect and report the error number that will tell us exactly what is happening.

Evidently this is known problem for T-Mobile users. 

1. Use SFTP instead of FTP connection. 
2. Switch off Passive mode under more Options. See screenshot.

Hope that helps.  If not, a Google search for T-Mobile can't connect to FTP will likely yield other things to try.
