I don't think there is a technical reason; I just think the provisioning system is setup this way to prevent Comcast reps from doing this. I'm assuming 99% of people on 300Mbps tier actually want 300Mbps. This way they don't create situations where customers complain about not receiving advertised speeds.
Cox was same way; I was on Ultimate tier (150Mbps) with an 8 channel modem. At the time, 16 channel modems (or higher) didn't exist. When Ultimate was bumped to 200Mbps and then to 300Mbps, they wouldn't update my profile for higher speeds until I got a 16+ channel modem.
Hello mjt3727
It maybe due to the 8 downstream channels Xfinity may need more than that to provide that speed but I would check with comcast again and ask for a explanation on this.
