I upgraded my modem to a Netgear CM3000 as I have a 2GB plan with Xfinity. I have the main Deco connected to the 2GB port (cat 6) on the modem however I'm not getting even 1GB speeds for downloads. The modem itself will change from white to blue when multi gigabyte is detected however it is only white. I rebooted the modem and router with the same issue and confirmed with Xfinity that it was provisioned correctly. Unsure how to achieve the 2GB Speeds for the Deco mesh system. It is wired backhaul to a second Deco x60 as well
