PTCL disconnection

Hey everyone. I have a problem with my PTCL router (ZTE version). I've been trying to upload a 150 MB file but the internet disconnects at around 70 - 90%. The internet is fine when I'm browsing or downloading. I've also tried uploading to different servers but the same thing happens.

Any help please?

You uploading via any ftp client or via your browser? change your DSL Modulation to G.DMT.

Uploaded through browser... How do I change my modulation?
