• MT7921K : https://patchwork.kernel.org/project/linux-wireless/patch/20230505000543.693532-3-greearb@candelatech.com/

Question 2

wlanpi hostapd mode not support 11ax, is it possible that hostapd installs without removing the # before

#CONFIG_IEEE80211AX=y

like

CONFIG_IEEE80211AX=y

Example:

The following is from the hostapd installation directory: defconfig 
------------------------------------------------------------------------------------
# IEEE 802.11ax HE support
# Note: This is experimental and work in progress. The definitions are still
# subject to change and this should not be expected to interoperate with the
# final IEEE 802.11ax version.
#CONFIG_IEEE80211AX=y
------------------------------------------------------------------------------------

thanks**

Hi @xiaodaimu710, for question 2, we are installing hostapd from bullseye-backports on our latest OS releases and are not compiling from source. You are welcome to uninstall the shipped version and recompile hostapd from source with your target definitions.
