Hi Gordon!Yes, the online speed tests I've tried vary widlly. I don't think the online test sites are ready for these faster speeds yet. I know Comcast's Powerboost has been a bit of a joke in some circles but it seems like now they have it working now for burstable packets, eh?My speed tests routinely max out at 10MB down, and the tests don't know how to report back those kinds of incredible speeds.Comcast is still working in our area. Two streets up I see three giant Comcast trucks with guys hanging from buckets putting up new lines. Pieces of what they don't use and cut away fall to the sidewalk, and one section of the new black, plastic, wire looked to be 2 inches in diameter with an inch of copper core in the center. Now that's a pipe!Here are two Speed Tests I just ran on DNSstuff.com and I think it shows Powerboost in proper action.First Test:Download Speed: 8199 kbps (1024.9 KB/sec transfer rate)Upload Speed: 2906 kbps (363.3 KB/sec transfer rate)Latency: 51 ms 5 seconds later Second Test:Download Speed: 10051 kbps (1256.4 KB/sec transfer rate)Upload Speed: 2886 kbps (360.8 KB/sec transfer rate)Latency: 50 msI think as Comcast senses your need for more power, it boosts you to its maximum available level. Pretty impressive.
