Is it normal my iPhone 11 Pro's wifi speed limited to ~450Mbps when i connect to AX8 5GHz?

Also note that WiFi-6 will realistically only give you like 5-10% increase in performance over WiFi-5, and maybe up to 15-20% in rare cases as 1024QAM is more sensitive to noise so don’t expect to be at max link rate all the time. WiFi-6 is more about better spectrum sharing especially in multi AP/router environments allowing for better performance in signal dense situations.

450 Mbps is actually pretty decent benchmark and, and also depends how close you are to the router and how many walls/floors are between you and the router as well. I wouldn’t expect more than say 600-800 Mbps peak real world throughout and that too at close ranges.

But does the iphone 11 has 1024QAM?

I just bought one and didn't tink it had it

I'm thinking of buying a router, it could help me a lot to make a choice
