I have an raxe300 connected to a cm3000

I have an raxe300 connected to a cm3000, and it says the internet speed is 470 mbps, when the computer is connected direct to the cm3000 it says the internet speed is 1149mbps. If I try to manually setup the raxe300 to a manual bandwidth setting, the max allowed is 1000 mbps, but when the computer is direct to modem I can get 1149 mbps. Why can't I manually set the internet speed of the raxe300 to a faster speed.

    Be sure your using the multi-gig WAN/LAN port to connect to the CM3000 modem. 
    Default on the RAXE router uses the 1Gb yellow WAN port. 

    CAT6A STP cable is recommended between the RAXE and CM modem.

     

  • Connected to the 2.5 gb wan port. The router will not allow me to select an internet speed on the QOS page of greater that 1000 mbps. Tha ACTUAL provisioning speed from my ISP is faster.  Router speed test, ( Probably due to the server they are using), is 470 mbps, computer direct to modem gets 1149 mbps, but again, the  router will not allow a manual speed selection of greater that 1000 mbps.

      QoS is not really needed on ISP speeds 1GB or higher. I'd disable QoS, reboot the router then speed test.

        I realize that, but the QOS page is where the INTERNET BANDWIDTH is either calculated, or input. If you notice, I didn't select QOS, I am working at the place where it says I want to define my internet bandwidth. 

  • Because if I don't it sets the speed to under 500 through the speed test that is incorrect, and limits the speeds of the devices connected tot he internet through the router. the router average speed test is between 460 and 480, but computer direct to modem tests at 1149. The speed test the router performs is inaccurate, and it will  limit throughput. HOURS of testing has verified all this.

      No it shouldn't.  That setting only kicks in if QOS is enabled.  If you just leave QOS off, the router should run as fast as the ISP lets it. 

       

      What upload/download speeds are you paying for?

      Mileage varies on all of the speed tests out there.  The measurement techniques all have quite a bit of error - especially on faster links. Plus the performance of the client hardware and the choice of internet server both affect the result.

       

      Since the RAXE300 has only one 2.5 gpbs port, either the LAN or WAN connection has to be gigabit (1000 mbps).  The fastest possible WAN-to-LAN speed is therefore 1000 mbps.  Any measurements higher than that on a wired client has to be a meaurement error - even if that client has multigig ethernet hardware.

       

      If your PC (like most) only has gigabit ethernet hardware, then that also apples to the CM3000->PC test you did earlier.

      It actually DOES affect the 2.5 port. IF I set it to 500 down, then my devices average 470, if I set it to 1000, I get about 870, the actual speed SHOULD be 1150 mbps down, but I am limited to 1000. 

      This is with QOS turned off?  

       

       

  • Yes, it is with QOS off. I am on the phone with a supervisor at netgear, and verified all the settings, and speeds, it's really frustrating. It's to the point I may look at an ASUS router. 

     

    The router to modem speed test on the router, was just under 450 mbps, the computer to the modem was 1149 mbps.

      If you are using the MG port with the CM modem and have QoS and all other features disabled and have a ethernet connected PC to one of the LAN ports, you should be seeing near 900Mpbs or just over with Ooklas installable speed test app on the PC. Be sure you select a different test server site on the app to compare results.

       

      Be sure to use CAT6A STP between the RAXE router and CM Modem. CAT6 UTP between the router and PC.

        The router to modem speed test on the router, was just under 450 mbps, the computer to the modem was 1149 mbps.

         

        Router says Internet speed is 443 this last test, COMPUTER to modem says 1147 this time. Computer through router with MANUAL speed selected of 1000 mbps is 880 last test. 1000 is the MAXIMUM speed the router will allow me to enter.

    I agree with Plemans. NG hardware has been always solid. FW and SW has been a rollar coaster ride and sometimes people may need to get off the ride. 

    Since I've been playing around with NG since around 2017, Seen various things and problems with NG and other Mfrs, including ASUS and D-Link which I do have a couple of there's. Always something seen across Mfrs.

     

    Been gaming for over 20 years now. After getting into a 1Gb/50Mbps ISP Speed, have not had any gaming issues with this service while using NG products. Learned many things with gaming, NAT and networking over the years. As long as ISP speeds are good, signal is good up to the modem and home networking is configured well, hardly ever see any gaming issues with NG routers. Though I leave most of the additional features disabled as I don't need them mostly unless I need to test something out. I'm the only gamer in my household so not much call for QoS, Gaming QOS or stuff that others have a need for. Gaming for me has been good with NG stuff. 


    The RAXE series is was it is and may have not been designed well or to have high speed seamless support across WAN and LAN ports. NG may have been tipping toes in the water to test new design flows and such as ETH speed for the home consumer finally went past 1GB. So for the RAXE series, the internet port and MG port is specific and handling is limited to the 1GB spec for the 1GB ports which will never go past this speed. Once NG finally came out with both WAN and LAN ports that all sported 2.5 or higher, it's been good for that design now. I've been able to fully support 10Gb down to the end points in my house now from the router point on the LAN side. I still have the 1Gb ISP service and honestly don't see needing anything past that. Just works well. 

     

    Will be putting my RAXE500 online maybe this weekend and a Orbi 770 series system online to test that configuration out. Hoping for good things.
