RAX120 internet speeds slows when using the MGig port with a CM2000
When connecting from my new CM2000 to the RAX120 using the MGig port, my internet speed drops from 900Mps (800 Mps service) to 650Mps. The Nighthawk IOS app test speed says it's working, but my hardwired computer connection speed changes. I have spent hours trying every combination and setting setups without success. Is there a step by step that is known to work?
Thanks
Wow, thanks for letting us know and the details.
Glad you got it working. Please mark your thread as solved so others will know. Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.

What Firmware version is currently loaded?
Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended.What is the connection rate seen on the RAX web page for the LAN port 5 to the CM modem? Found under Advanced Tab/Show Stats button. https://community.netgear.com/t5/Nighthawk-with-WiFi-6-AX-and/New-RAX120v1-and-RAX120v2-Firmware-Version-1-2-9-52-Released/m-p/2338765/highlight/true#M35435
Using Ooklas installable speed test app on your wired PC?
Try a different wired PC to compare speed results?
Please post a copy and paste of the modems connection status and event log page.

https://kb.netgear.com/30008/How-do-I-view-or-clear-the-event-logs-on-my-NETGEAR-cable-modem-or-modem-routerHi,
- RAX120v2 Firmware version: v1.2.9.52
- Connecting cable: Lutron certified CAT6, 6ft long
- WAN port: 1000M/Full
- PC Ooklas speed: 940.36 (LAN 1)
- Does the approximately the same speed on second PC (LAN 2)
The above is how it is presently running. The issue is when I try to use the MGig connection on the router the speed drops from 940 to 609. After a router reboot, the speed is 558. The Nighthawk iPhone app says its 940 on either the 1Gig or the MGig port connection. Below are the stats with the MGig port.
Why do the 1Gig LAN router port speeds drop when using the MGig port on the router?
Sorry. Not very good yet with this site. This is the setup that I'm presently using to get the 940 Mbps. The internet speed on my PC drops when using the MB port on the router.
Still having issues. There is something about toggling QoS on and off when using the MG port. If not getting the speeds you expect, toggling the QoS on and off restores the MG port speed. I’m now using the MG port and get the same speed as when using the 1 gig port.
I don’t think it’s the MG port per se, I’m convinced it has something to do with the way QoS is being handled.
That’s my two cents. But I’m now having expected speeds using the MB port.
Still evaluating.
Are the speeds stable when QoS is fully disabled or enabled?
Does disabling QOS all the time have stable speeds?
What ISP speed do you pay for UP and DOWN?
The speeds seem to be stable with QoS on or off. The Speedtest curve is different, but it usually repeats either way.
My internet provider is xFinity (Comcast). I pay for 800Mbps down and 20Mbps up. I usually get 930Mbps down and 24Mbps up.
The issue I was having was when using the MG port, the 930 would drop to 650 (I aways get 930 when using the 1Gig internet port). For some reason, toggling the QoS on and then off and back to on, restores the speed to 930 from 650. It also works to toggle the QoS from off to on and back to off.
Using Speedtest with QoS on, the speed curve starts off lower and bills up to 930. With QoS off, it climbs to 930 faster and flattens out.
I didn't know there were these issues with the MG port until I got a CM2000 for future speed upgrades from my current 800 plan.
At this point, toggling QoS seems to correct the speed issue.
