Do NOT switch to DirecTV's internet service, HUGHESnet I believe?
It is the most horrid piece of crap internet I've ever experienced. I had it for a few years before DSL became available in our area. You could download 200MB a day and then they reduce your speed to < Dialup speeds. Online gaming is impossible. No Xbox Live, No WoW, No BLOCKLAND. And, to top it off, it was > twice as expensive as our DSL, and it costs about $500 just to get it set up.
Don't bother with it. It sucks.
Edit: This was a year ago. That's how it was for me. You may have a better experience, but don't say I didn't warn you.
