Yes, the overage was the result of an Office download as I mentioned. Not the video streaming. I'm more concerned about the constant buffering that occurs when trying to watch videos from Amazon Prime.
"Amazing speeds" isn't an exact amount. For someone who lost cable and switched to Hughesnet, that moniker probably won't fit. Yet for someone coming from dialup, it certainly would. That's normally who Hughesnet customers are...former dialup users who just got tired of it and cannot get a land based (or even cell type) service.
From what I've read, Amazon Prime requires a speed of 3.5Mbps for HD, and 1.5Mbps for SD. For many, during the evening peak usage hours, the 3.5Mbps speed requirement can be hard to meet. Occasionally even the 1.5Mbps speed requirement can be difficult to meet. Hughesnet has a finite amount of throughput that is more restricted than a land based ISP, and when many people get on at a certain time, everybody's speed slows.
For some it may work, and for others not so much. It all depends on how many people are online on a beam, on a gateway and on in total, and what they are doing.
