I have the nighthawk RAXE500. With the Nighthawk CM2000 cable modem

Hello. I have the nighthawk RAXE500. With the Nighthawk CM2000 cable modem. Internet is with Comcast. I'm paying for 1200mps but only getting 920. I try to define my own bandwidth but keep getting invalid unlink bandwidth when entering 1200 dl and 50 ul

  • How is the modem and PC connected?

     

    Due to the CM2000 having a single 2.5GbE port, in order to get a 1200Mbps WAN connection to deliver more than 940Mbps to the router, you will have to connect it to the 2.5GbE port on the router, and set the internet to use the 2.5GbE port.

     

    After that, an annoying aspect will be that the client device will either need to use 2 stream 802.11ax on the 5GHz band (e.g., an Intel AX200 or better WiFi adapter), or a PC with 2 Ethernet ports where you can enable LACP, and then use 2 cables to the PC.

     

    The reason for the above is that the router only has a single 2.5GbE port and every other port is a 1GbE with LACP support for teaming.

    If your PC only has a single 2.5GbE port, then an alternative is to have a 2.5GbE managed switch, and then have it use LACP and 2 Ethernet ports for an uplink to the RAXE500, and then every other device can connect to switch using 2.5GbE.

     

    Beyond that, for now, the easiest solution is 2.5GbE between the modem and router, and client devices using WiFi, even when in the same room, since on the RAXE500, the 5GHz band with an intel AX200 client, will get 1.8Gbps+ over WiFi.

        Does that mean that the suggestion from Razor512 fixed the problem?

         

        If so, why not is Accept as Solution on that message?

         

        It could help later visitors who turn up with the same problem.
