Have the ISP check the signal and line quality UP to the modem.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Be sure to speed test with a wired PC directly connected to the CM modem with out the NG router in the mix. IF you you have the R6400 series router, this router may not be capable of supporing near 900Mbps on the WAN to LAN speed tests.

It's a bit of a hassle but you can also rent one of Comcast's gateways for a day or two and have it provisioned and compare speeds. If you get similar speeds then you know for sure its an issue with comcast provisioning or your cable lines. If the speed is much faster then you know the culprit is your equipment

the reason I bought my own equipment is because I already tried their equipment and it sucked. I would assume most people who buy their own equipment do so because of the problems with their equipment.
