CBK40 Orbi with ATT Fiber

I currently am switching from Comcast cable to AT&T fiber with an existing CBK40 system. What is the best configuration for the AT&T box with the CBK40?

Well, this has been my intuition all the way so thanks for confirming the facts. I will use the AT&T system with an expander that they provide to see if this is enough to cover my house.

I can't return the CBK40 so I'll try to find a way to provide value to someone.

Thanks for the advice on clearing the ISP as well. I'll get this off Comcast as soon as the AT&T is up.

Thanks for the information. It looks like I might need a backhaul unit as well. I'll know more tomorrow following the AT&T installation. Since AT&T also sells Orbi units in their stores, the techs should be able to work with my CBK40 setup and make recommendations if required.

Hopefully they can keep the Orbi cablemodem as the gateway. I can only run in gateway mode or bridged.

Good Luck.

  My concern is that the modem capability in the CBK40 might limit the flexibility as compared to the router only unit in the standard configuration. More tomorrow.
