That is a normal ratio of down to up for DSL. At least all of the DSL connections I've seen. Dish says 3.0 down should work. That would be about a .5 up speed.
Are you saying the service does not work with anything but a cable internet speed?
Maybe I am missing something.
Thanx
Our DSL is about .850 up and it looks pretty good on Dish Anywhere remotely. My daughter's DSL is about .250 up and it works good and doesn't look that bad.
