I know this.  I've got 10 Mbits down and 1 up.

How fast is your Century Link service?  Are you stuck with dsl or do 
they offer something faster?  I've heard that many ISPs are imposing 
data caps now so they can screw people out of more money.

I got one of those threatening emails from AT&T saying I've been naughty 
and listing the torrent in question.  I use a VPN now and get no more 
nasty emails from the isp.

I used to have a roommate about 10 years ago who bogged down my internet 
connection with his stupid online shoot em up games.  I couldn't 
download anything.  I'd connect to the router and see that he was 
downloading little but maxing out the upload speed. It must have been 
something to do with that docsis issue you mentioned.  I fixed the 
problem by setting a limit on his upload speed so he only got half of 
what was available.  He complained when implementing this change kicked 
him offline for a minute or so, but not after that

emials from my ISP.  Thanks for your reply and also thanks to everyone
