Could you try it with attached hostapd configuration file? I use default configuration but change below interface=wlan0 ssid=test-8821ae hw_mode=a channel=149 The driver I use is built-in in kernel 5.9.10. The hostap is hostap_2_9-1731-g56a1df71e (just list the version I use; I believe other version also work) --- Ping-Ke
