Hello, thanks for your answer.
I'm creating the connection on band wifi band a using this command: nmcli con add type wifi ifname wlan0 autoconnect yes ssid $(hostname) 802-11-wireless.mode ap 802-11-wireless.band a 802-11-wireless.channel 100 ipv4.addresses 192.168.201.1/24 ipv4.method shared wifi-sec.key-mgmt wpa-psk wifi-sec.psk TEST12345 I had a few problems to bring up the access point first, but when I changed the 802-1x.auth-timeout to 90 seconds (CAC time) and send the correct country code to wpa_supplicant over dbus the access point is coming up as it should. Everything is fine until I need to switch the channel because a radar event is detected by the driver. To simulate the radar event I use a debug feature of the WLink8 driver. I use the debugfs and write the channel to a specific file: echo 100 > /sys/kernel/debug/ieee80211/phy0/wlcore/wl18xx/radar_detection for triggering a radar event on channel 100. We used this in the past with hostapd and it worked really good. I'm not sure how I can tell wpa_supplicant to use wlan0 instead of p2p-dev-wlan0. I only create the nmcli connection and I think the network manager is then configuring wpa_supplicant over dbus.

Do I > just need to add some extra configurations? Yes, I think it should if you set property 'wifi.band' to 'a'.
