Upgraded cable modem. Speedtest here shows strange warning

Comcast Xfinity internet.
Got tired of the crappy modem I was renting from Comcast so I bought a Motorola Surfboard sb6121

Got it activated and ran speedtest on several sites including here.
The DSLReports test showed me the following message. I've asked 2 Comcast techs about it and neither has any idea what it means.

Warning: You connection shows signs of ISP upload compression.

My speed test results are below. Not too bad.

Google turned up a bunch of hits, mostly old ones but there was this one hit from here at DSLR that talks directly to the issue with the speed test from DSLR.

»Get warning message during speed test???

Thanks!
I just had to call comcast and they had to re-register my modem. Apparently they have been having trouble registering modems today. The thing I was running in to was some sites would load fine but others would take me to the comcast activation page. Sometimes sites would load fine once and next time go to the activation page. He got it all working fine now.
I guess I really can't complain too much, the broadband plan I am on is advertised 12 Mbps down and I always get at least 20
