Go to the Comcast Office, locally, and get one of their new Docsis 2.0
modems. Do the rental agreement thing. Take it home and go thru the
process to get it up and running, then do your speed tests. You should
have a 2 week return policy if you don't like the way it works. There
HAVE been some complaints that the 2.0 modems are doing exactly the
same thing your 1.1 version is doing. BUT since it is essentially free
to try, try it.
