Boot file update for Motorola MB7621 modem
I have a Motorola MB7621 modem that can only reach 60 Mbps speed when my plan is for 300 Mbps. The Wifi router is designed for up to 450 Mbps, so that's not the issue.
I believe that the bootfile /config file is the matter, looking at these other problems with the same modem:

What is the config file the modem is getting? You can find it listed as "Configuration File" on http://192.168.100.1/MotoConnection.asp.
What is the model number of the router you are using?
Are you connecting via Wifi or Ethernet? If Wifi, it's best to switch to an Ethernet cable connection if possible for testing. That would allow you to determine whether the problem is the Wifi signal or the link between your modem and Comcast's network. Network connection problems that affect both Ethernet and Wifi devices are often due to poor coax connections or damaged coax cable, usually in or near your home.
If you want to troubleshoot this yourself, please see Internet Troubleshooting Tips. If you still need help, please post your Internet plan speed and the following information from your modem (from http://192.168.100.1):
If you can't find the problem or you'd rather have Comcast take care of it, call them at the phone number on your bill or 1-800-Comcast, or use one of the options on https://www.xfinity.com/support/contact-us/. It's not likely they can fix the problem remotely. If not, insist they send a tech out to identify the cause and correct it.
If the tech finds bad coax, splitters, amplifiers, or connections in your home (even if Comcast originally supplied them) you'll probably have to pay for the visit ($70-$100) unless you have their Service Protection Plan ( https://www.xfinity.com/support/articles/service-protection-plan, closed to customers that don't already have it). If the trouble is due to a faulty Comcast rental device or anything outside your home you shouldn't be charged.

Router model number?
Wifi or Ethernet? If Wifi, can you try Ethernet?
How are you measuring speed? What device are you measuring it on? Connected how?
