Solved RAX50 - Only 600MBPS on Wifi?

[Spartan]

I have a Dell XPS 13 9310 which has a Killer WiFi 6 AX500 WLAN card in it. I only get up to 590 MBPS approximately on WiFi with my Netgear AX6 RAX50 router so I thought it was my WLAN card in the laptop as I get the full speed of my bandwidth when connected via an external hub's wired LAN.

I was checking the settings today and I noticed this:



Does that mean this router only supports up to 600 MBPS on WiFi??

My bad, I think that's only for the 2.4GHz as I just noticed if I scroll down it shows 5400MBPS for the 5GHz band.
