The Motorola MB8600 is a powerhouse, and I understand why you'd want to utilize its LAGG capabilities to hit those 1200 Mbps speeds without buying new gear @user_6e7344. You can always provide your feedback here: https://www.xfinity.com/support/svp-c
Why is LAGG not supported on the MB8600 anymore?

Horrible customer service in home
I placed three phone calls to Xfinity on separate occasions to ensure that my move would be seamless. Each time I was told something different, but was assured everything would be fine and ready to go on my move-in day. Well, of course it was not. Nothing was connected as promised on my move-in day.

Concern moved here to the Customer Service help section for greater exposure to Comcast corporate employees (The Digital Care Team) for assistance.
