Command aborted. Server timeout.

Hello,

My problem is ftp that used to connect ok with exactly the same settings it doesn't connect anymore. Is not a problem of ftp program or server because tried several (smart ftp, dramweaver, internet explorer)
Is not spyware or virus (checked both)
Im under win xp, adsl 256 kbp connection in Argentina.

What could be the problem?

That's what smart ftp says:
