So Xfinity upgraded my internet to 600mb

So Xfinity upgraded my internet to 600mb and they are telling me my modem Moto MG7550 won't support that speed. They were correct cause the highest I'll get is 373. I decided to buy a used Netgear C6900 off of OfferUp. Apparently the built in wifi doesn't work. I read somewhere on Reddit I can use two cable modems but one has to be in bridge mode. I put Netgear in bridge mode and then connected both modems with a network cable. I have internet thru Netgear but no internet wifi thru moto. Although I can connect. I know I'm missing something.

    Why are you using two modem/routers on your network? That is an invitation to chaos.

     

    No need ro rely on something you read "somewhere on Reddit", here's the local advice:

    Apparently the built in wifi doesn't work.

    For the C6900, bridge mode means that you bypass the router bit. So there is no WiFi from it, because you turned it off.

     

    You may get Wifi from the other thing, but it won't have an Internet connection. The Netgear modem has to be before the Moto MG7550. And it doesn't have a "router only" mode.

     

    In other words, you can't use the Moto MG7550 as a router behind the C6900. There's no WAN port on the back.

     

    So, back to the original question, why are you using two modem/routers?

     

    A better approach would be to ditch the Moto MG7550 and use the Netgear modem/router in modem/router mode.
