I am trying to connect WiFi-6E Access point with AX210 card installed on ubuntu20.04.04 with kernel 5.10.0. i have removed/renamed the pvnm file as suggested here the wifi card is configured well as i dont see any error in

sudo dmesg | grep iwl.

i am using wpa_supplicant ( version 2.9) to connect to Wifi access point. My wpa_supplicant.conf looks like.

p2p_disabled=1
network={
        ssid="wifitest6E"
        #psk="aaaa1111"
        psk=edf145768310b75d365dfc1e3befb58c782e6d9ac63df83a709d200a6a238492
        key_mgmt=SAE
        sae_password="aaaa1111"
        ieee80211w=2
}

i am getting the following error in log when i run the command below.

sudo wpa_supplicant -d -c /etc/wpa_supplicant.conf -i wlp1s0

wlp1s0: 17: 1c:9e:cc:21:99:7a ssid='wifitest6E' wpa_ie_len=0 rsn_ie_len=20 caps=0x1111 level=-43 freq=7055
wlp1s0:    selected based on RSN IE
wlp1s0:    hardware does not support required rate 61.5 Mbps (freq=7055 mode==2 num_rates=8)
wlp1s0:    skip - rate sets do not match

iwlist freq gives the following optput

Cleared the older logs and adding the logs with just one wifi210 card.

wlp3s0:    selected based on RSN IE
wlp3s0:    SAE H2E disabled

i added the below line in wpasupplicant.conf and the wifi interface could connect the access point :)

sae_pwe=1

Thanks for posting this, that fixed my issue too.

The sae_pwe=1 configuration option is only supported from wpa_supplicant 2.10 (which currently is the latest release) onwards. Current version distributed with Debian is 2.9. So you might need to upgrade wpa_supplicant to 2.10 first to enable sae_pwe=1. Otherwise, wpa_supplicant will complain about unknown configuration option.
