As you know, we can't get your ISP to remove their upload filters.

I had to sign up with a competitor to show my ISP that their filters were interrupting my uploads, just like yours.

Thanks to the head of help desk, the internet admins worked out a way to put my cable modem on an unfiltered line, so I stayed with them rather than switch to the competition.

Try signing up with the competition (many offer a free 2 month trial), and see if that helps.

If you want to know *how* the ISP's filter the uploads, google for "Sandvine." For *why?*, Google aslo has many articles on "bandwidth shaping."
