Trouble Setting Access Point 2.4GHz Orange Pi Zero 2

I'm setting up a WiFi Access Point using bridge mode. I successfully configured the bridge mode and it's working. Then, I managed to set up the WiFi Access Point for 5GHz as well. But why did I fail when setting it up for 2.4 GHz? Trouble: 1. Visible after restart, then after 1-2 minuter, WiFi AP not visible 2. After restart, i cant access my orange pi with ssh or VNC, but can access with HDMI This my configuration: sudo nano /etc/hostapd.conf Script: # # orangepi hostapd configuration example # # nl80211 mode # ssid=HIBOBGATEWAY interface=wlan0 hw_mode=g channel=6 # Set to a common 2.4GHz channel (1-13) bridge=br0 driver=nl80211 logger_syslog=0 logger_syslog_level=0 wmm_enabled=1 wpa=2 preamble=1 wpa_psk=66eb31d2b48d19ba216f2e50c6831ee11be98e2fa3a8075e30b866f4a5ccda27 wpa_passphrase=6666666666 wpa_key_mgmt=WPA-PSK wpa_pairwise=TKIP rsn_pairwise=CCMP auth_algs=1 macaddr_acl=0 ### IEEE 802.11n ieee80211n=1 ht_capab=[SHORT-GI-20][SHORT-GI-40][HT40+] country_code=ID ieee80211d=1 ### IEEE 802.11n ### IEEE 802.11a #hw_mode=a ### IEEE 802.11a ### IEEE 802.11ac #ieee80211ac=1 #vht_capab=[MAX-MPDU-11454][SHORT-GI-80][TX-STBC-2BY1][RX-STBC-1][MAX-A-MPDU-LEN-EXP3] #vht_oper_chwidth=1 #vht_oper_centr_freq_seg0_idx=42 ### IEEE 802.11ac # controlling enabled ctrl_interface=/var/run/hostapd ctrl_interface_group=0 For bridge setting: sudo nano /etc/network/interfaces Script source /etc/network/interfaces.d/* # Network is managed by Network manager auto lo iface lo inet loopback auto eth0 allow-hotplug eth0 iface eth0 inet manual auto wlan0 allow-hotplug wlan0 iface wlan0 inet manual #wireless power off auto br0 iface br0 inet static address 192.168.6.57 netmask 255.255.255.0 gateway 192.168.6.254 bridge_ports eth0 wlan0 bridge_fd 0 bridge_stp off Copy code Can you help me?
