802.11r/k/v Fast Roaming / Fast Transitioning not working

Hi everyone! I'm a newbie (got my first openwrt router a week ago)

Setup:
2x Routerich AX3000 (OpenWrt 23.05.5 r24106-10cc5fcd00)
First is connected via PPPOE to ONT
Second is connected via lan and configured as dumb AP
Smartphone: OnePlus 8

Moving to story:
At first I configured wifi 5 with the same parameters on both devices (same SSID, wpa2-psk/wpa3-sae mixed, same password), went to WLAN roaming and set everything in the list.

Next I installed usteer (luci) on both and set:
roam_scan_snr -50
roam_trigger_snr -50
signal_diff_treshold 4

Also I set first router on channel 52 with 40 MHz, second on channel 36 with 80 MHz.

And nothing worked.

Then I was suggested to set:
roam_scan_snr -60
roam_trigger_snr -64
min_snr -70

Well, after that my smartphone changed to channel 36, but after 10 seconds it disconnected from wifi and couldn't connect.

I went to logs and saw
EAPOL-4WAY-HS-COMPLETED
Instead of
FT authentication already completed - do not start 4-way handshake

After some researching I changed mixed wpa2/3 to just wpa2-psk, but my phone was denied access.
So I just gave up, because I spent almost whole day.

Maybe you can suggest something?
I want to try DAWN instead of usteer.

Also btw I don't want to lower the power of my routers wifi, I want them to move my devices when their signal is lower than fixed value (-52 dBm for example)

And now I will just use two APs with different SSID's

I've lost the battle, but not the war
(Sun Tzu I guess) :grin:

WPA3 has downgrade prevention.

Oh, I got it, thanks
