I have been a Wildblue customer for almost 2 years. I have never had the download speed that I paid for and I even upgraded!
They have a Fair Access Policy which will prevent you from even getting on the internet if you exceed the download amount you pay for, but that is bound to happen because you have to keep your computer running for hours, even days in order to download anything. Their excuse when you call their poorly named customer service department is "many people are on the web, so it slows the speed". So, from anywhere from a few days to a few weeks you can barely get on to check your email and it take several minutes for a page to load.
Everyone that has signed up for Wildblue in my area is complaining of the same problem. Basically, you are paying for internet service, but not getting it, and you still have to pay no matter how slow the service is!
