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.
Well, the thing is, the CBK40 system can only run in gateway mode or bridge mode, meaning that when in gateway mode, it has to be the ISP modem interface with the ISP service. When in bridge mode, the router portion of the CBK40 is disabled and it becomes a modem only. I believe this also disable the wifi MESH system as well. I haven't tried this with mine yet.
You have just clearly described my dilemma. Depending on the way the AT&T box can be configured will determine if it can just be a fiber optical gateway/translater that will allow the Orbi to interface and appear as the primary modem. Even then, I am not certain that the Orbi can use the ethernet connectors as a modem input since the primary cable input is for coax cable and there is no WAN input as on the router only version. I admit to a bit of ignorance as to specs, but will experiment to try to identify any solution.
