So, I went ahead and purchased the Motorola MB86000 modem that Comcast clearly states supports gigabit speeds. When I called to upgrade to gigabit, I was told that they only supported it with rented equipment. Is this true? Why? If so - they should update the device info page to reflect that.
NOT true !! Try another rep.
Slacker3000, you can definitely use an owned modem for Gigabit Internet. You can view the approved modems here: https://mydeviceinfo.xfinity.com/
If you already have a modem that you've purchased, I'd be happy to help set it up if it's not already active! We're here to help.
