The client device decides which band to use. Did you verify that there is a 6 GHz BSSID?

Actually, I had my WLAN set to WPA3, but, I saw LDAP auth server and aruba 9240 controller were still using WPA2 key in the command output 'show auth-tracebuf'
does this practically affect to wireless terminal device to use 5 Ghz?
my phone is Galaxy S23 Ultra that supports WiFi-6E

Did you set the WLAN to use WPA3? 6 GHz requires WPA3. Run "show ap bss-table" from the controller to validate the AP is creating a BSSID for 6 GHz.
If 6 GHz is broadcasting and your device doesn't see 6 GHz as an option, the problem is with the client.

Hi I am Chang, Aruba Korea's Reseller Partner
My customer uses 9240 controller(OS 8.10.0.8 LSR) and AP-655 for their office wlan infra.
I want to know which one is better to avoid radio interference, enlarging user's through put, small load and less damage to AP-655's Power, and so on
1. Enable All Radios 6, 5, and 2.4 Ghz band
2. Enable two radios 6 and 5 Ghz band (disable 2.4 Ghz)
and actually I enabled 6 Ghz Radio Band, but wireless terminal devices don't get attached to 6 Ghz (exactly "6E"), but only 5 Ghz
please give me the reason why and how to fix it ( I heard band-steering is not supported)
