Nighthawk AC1900 Wifi Cable Modem Router works with ATT fiber in passthrough mode

[kathyyar]

Guys, I just want to know if my model Nighthawk which I purchased for use with Xfinity can be successfully setup with ATT Fiber internet.  I am trying to use the passthrough function on the BGW 210 (SLOW) router modem provided with the service. The exact model I have is AC1900 (C7000v2)

No. the C7000 is a cable modem only. It won't work with your fiber connection. 

Potentially you can get it to function as a type of access point but not as a router. 

You can try the guide here if you'd like:

As you say, no can do, but would it be even much use for @kathyyar  to repurpose it as an access point?

The C7000 is an ageing (2015) modem/router with wifi from that era. Given that fibre Internet could well be on the fast side, would the C7000 be a bit of a blockage on the network?

I have no idea what performance they pay for or if it'd even be a benefit. But just putting the info out there in case they want to try 🙂

That's what I "thought" but I really appreciate your response.  I worked on it last night and it appeared to be a no go....

You have saved me lots of time!
