Hey there, today I came across your post while trying to set up a 6GHz AP on a NetGear A8000.
Actually the HE PHY Capabilities
showing no 6GHz seems to not really be relevant here.
I think you are just missing the op_class
setting from your hostapd
conf.
I am not done with testing but the following config snipped seems to successfully create a 6 GHz AP:
hw_mode=a
channel=57
ieee80211ax=1
wmm_enabled=1
op_class=131
ieee80211w=2
auth_algs=1
wpa=2
sae_password=password
wpa_key_mgmt=SAE
rsn_pairwise=CCMP
Note: You have to compile hostapd
with CONFIG_SAE=y
and you need wpa_key_mgmt=SAE
because otherwise you will get the error Management frame protection is required in 6 GHz
or Invalid AKM suite for 6 GHz
.
