Is it normal my iPhone 11 Pro's wifi speed limited to ~450Mbps when i connect to AX8 5GHz?
I just bought AX8 yesterday and I connected to 5GHz and the results were all limited to around 450Mbps (451 highest), is it because of the channel i chose? (I'm using 160), and which chnnel or settin...

to use the full 160hrz spectrum you need to be using the dfs channels. so make sure that 160hrz is enabled, that you've selected 4800mbps, and that you select the lower spectrum 5ghz channels so you can utilize dfs. I could be wrong but my understanding was that if you select the higher 5ghz channels, it auto selects 2400mbps and not 4800mbps.
- cyruslegoOct 03, 2019AspirantOh yes sorry should be 161, should i switch the mode to 4800mbps?

It'll auto switch you back to 2400mbps until you set your 5ghz channels to the lower spectrum. So set your channel selection down and then set it to 4800mbps.
- avtellaOct 03, 2019ProdigyIf I recall correctly, the iPhone 11 does not support HT160 it’s HT80 only. Also I believe there are some issues with the WiFi firmware that were supposed to be fixed on the iPhone 11 in the recent .1 iOS update.
If it’s any solace, either way I doubt it makes much of a difference on a mobile device as you’d realistically probably never use anywhere close to that much bandwidth on a phone at any given time other than benchmarks like Ookla or DSL Reports.- plemansOct 03, 2019Guru - Experienced User

- avtellaOct 03, 2019ProdigyAlso 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.
