rental modem vs owned modem

I have been a business customer for about 3 years. I recently upgraded from 50 to 150 speed and also decided to buy my own modem.

Before I hooked up my new modem, I ran a speed test on my Comcast modem (high 170's as an average). I then installed my Motorola MB8600 and got it working with Comcast. I ran some speed tests and these run in the neighborhood for low 140's. I am surprised that there is a 30Mbps deifference......Is this normal?

 

I have the same computer, cables and router (I even speed tested without the router)

You can't just buy a modem and have at it, Comcast needs to send it the correct boot file that configures it properly.  You have to call their tech suppport and have them change the configuration in their system for your modem model.
