Currently using Comcast Xb7, I was using SB6183 and Netgear R7000 router. If I hook up the R7000 with Xb7 with Bridge mode will my speeds improve, stay the same or get worse? I have no AX devices so I would like to get some use still out of the R7000. Is the router inside the Xb7 better than R7000 at this point? Would like suggestions if anyone else is using this setup.
