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 s...

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.

NG may have only set the QoS input value to max out at 1GB. Since the default port was for the 1Gb port. May have not applied this to the Multi Gig port.
QoS isn't required for anything past 1GB. So you'll need to use it as is or disable it. I'd leave it disabled.
Besides the QoS database is 5 years old and would be no longer updated by NG.

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.

Welp, if you have the CM3000 connected to the multi gig port, most likely you are getting your over 1Gb speed at this port. However since ALL other ports are limited to 1Gb max, setting QoS to anything higher would not work since all other LAN ports max out at 1Gb. So this maybe why you can't set QoS to anything over 1Gb.Only way to attempt to check this would be to have the MG port connected to the CM modem and have a 4x4 wireless device connected to the 6Ghz wifi signal then run your speed test there. If all is connected here, then you may see over 1Gb speeds on wireless. Otherwise, your limited to 1Gb on the LAN port side. NG didn't add MG LAN ports until the BE series. Same issue we saw on Orbi AX systems. MG ports but no MG LAN ports until the 960 appeared. Then BE series saw more MG LAN ports.

Why do you think you need to define it?
- DarkattSep 08, 2026Aspirant
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.

This is with QOS turned off?
