I use Shaw, have the "Extreme" 10mbps package, and get a pretty consistent 10mbps. The powerboost maxes out the capacity of their cable modems (25mbps) for 5-20 seconds and drops you back to your prescribed speed. In BC you can buy Shaw Nitro which puts you at 25mbps all the time. What Comcast is doing sounds more like selling the service at 10mbps, throttling their customers to 1.5 for every day browsing, and using this same PowerBoost when they run bandwidth tests. Which, ultimately, is fraud imho.
