I'm not getting anything as fast as those speeds, however what is interesting in my case is that I'm getting more than double what I'm supposed to get (I'm on Comcast and according to my plan I'm paying for 12MB/sec):
This speed is also consistent. No matter when I test it, it is always > 25MB/sec.
I guess all I can say here is you are paying the folks who had a hand in destroying the tech tv cable channel and shows I used to watch .... Leo and the crew are still around but the cable channel is gone....
Comcast bought them and in no time at all they were gone.
