Check for any cable line splitters and remove them if seen. 

Contact the ISP and have them check there signal up to the modem.

Try a different CM modem. It's possible that your one unit could be faulty.

thats going to be a pain to return to bestbuy then going thu the hassle with comcast again. it did reach 900mbps on fast.com. Is that a good test website for speeds?

Ya we know. Need to check to see if different modem does samething to compare. 

I use Ooklas installable speedtest app for Windows or Apple.
