RAX80 Wired Connection Speeds

Question

I apologize if this is in the wrong board. I have a brand new RAX80 and am connected to an XFi modem in bridge mode. If I run speedtest from the Nighthawk GUI (advanced>Setup>QoS Setup>Take a Speedtest) I get download/upload speeds of 920Mbps/42Mbps. If I run the same speedtest from a wired PC I get 523Mbps/42Mbps. Why is there such large discrpancy in download speeds? My PC is equipped with a I219-V ethernet card. For what it's worth, if I plug directly into the modem, the speeds wired speeds are 920Mbps. So I must conclude the Nighthawk is doing something, but what???

Firmware Version
V1.0.1.64_1.0.27

Thanks for the help.

There's the same issue reported for the RAX120 where the lan speed drops by about half.
There were some suggestions that turning off QoS fixed the problem but this didn't seem to be a solution for all.

Just another issue in the long list for the RAX devices....

I did find that turning on/off QoS really did help. My speeds are as expected now.

I tried that also and didn’t affect it at all. Maybe this thing just sucks. Guess I will put my ole trusty luxul back in

Try going into setting and enable QoS.... wait a few minutes.... then disable QoS. After doing that should get full speeds... if not try it again and should fix it. If you reboot the router have to do it again. Seems QoS gets enabled even though it shows as disabled so only way to turn it off is to turn it on, wait, and turn it off in GUI.
