You'll never be able to get 800 with that device as it is rated for only up to 374;
https://www.xfinity.com/support/devices#details
What happens when trying to get speeds that a device is not capable of delivering is that it defaults to using a slower speed tier configuration file.
You need to use a compatible device. They can be found at that link above.
