As I explained in my first message, we're providing our selves with ADSL. Since we are further than we should be from the other end, we only barely get a connection. However, this gives us 816K up and 680K down for about $10/month. It is worth some optimization on the link. Fast retransmit is an something that reacts in less than a second?
