Hello, 

I got a problem about the S21 Ultra device, which dosen't work WiFi roaming on 6GHz.

As know, For Wi-Fi Roaming funtionality, the S21 Ultra should support 802.11r, 11k, 11v. 

While doing a Wi-Fi roaming test between APs almost one month, have reached to a conclusion says it woks well in 2.4GHz and 5GHz bandwidth  , but in 6GHz 

After engineering , some says it seems like the device dosen't support some funtionalities related 802.1x authenticastion and WPA3 secutity protocol in the 6GHz BW.   

For your understanding, my test environment as below.

: S21 Ultra supports 6GHz a.k.a WiFi 6E, Access Point supports Wi-Fi 6E

Please advise on how to solve this problem.
