Finally!

Called TSTT for the third time today and a girl called Adonna told me to press the reset button for 3 seconds (no more, no less), turn off the computer for 5 minutes then turn it back on and the DSL should be working. It wasn't ... but she then took me back into the Speedstream site (which many technicians had taken me into before with no results) and a new thing popped up where I had to reinsert my username and password a few times - which I did ... and voila! I have back my DSL! Up until now I don't know what was wrong, but at least it's working again.
