Unless it's absolutely necessary, your Internet traffic is getting to you without satellites. When the traffic is coming over a link via a geosynchronous satellite, the difference is very noticeable. It's capable of high throughputs, but the long distances involved mean high latency on every transfer. Since every TCP/IP block transfer is subject to a "handshake", the whole process of opening a single web page slows right down over satellite.
Video transfers etc. over satellite use different protocols that allow for more "in flight" data, not TCP/IP.
