Why is my download speed slower than speedtests say, thinkbroadband says i should be on 6meg im download at 1?

It's a trick, they advertise your peak download speeds, but in reality if you read the fine print, you are only entitled to this "peak speed" for a certain period of time, then you go down. The best solution to get kick *** speeds (kinda pricy though) is to switch from broadband to fiber optic internet connection
