Low data rate in 5ghz netwrork

[Yarael]

Hi,

I recently modify my network to a full 802.11ac 5Ghz network and I can’t have more than 175Mb up and down (test on some AP’s alone, one device, nobody else).

have you an idea to resolve this ?
I have a 1gbps fiber connexion (up/down)

AP’s in my network are AP 130 230 550 1100

I'm using iPhone 13 Pro, iPad Pro M1, iMac M1, to run my test (MIMO 2x2 I think) with 40Mhz channel.

Some questions:
- what are the WiFi specifications of the client (2x2:2, 3x3:3,...)?
- what is the channelwidth of the SSID you are using?
