While the data rate may be adequate, you will get killed by the propagation delays. When you click on something that requires action at a website server the request goes 25K miles to the satellite, then it goes 25K miles to Hughes ground station and on to the internet and on the website server. Then the website server responds to your request and it goes to Hughes and then 25K miles to the satellite and then 25K miles back down to your computer. Speed of light is 186K/second and you've added over half a second to the response of the website server. Trust me you will more than notice the delay.
