hostapd err on orange pi zero 3

[JIN PRO]

Every time the device is turned on, I can start hostapd for the first time. When I ctrl-terminate, the next time I start hostapd, I get an error message:
Failed to set beacon parameters
Interface initialization failed
wlan0: interface state UNINITIALIZED->DISABLED
wlan0: AP-DISABLED
wlan0: Unable to setup interface.
wlan0: interface state DISABLED->DISABLED
wlan0: AP-DISABLED

try

 

ip link set wlan0 up

It doesn't work. The wlan0 status is on. I think it's a kernel driver problem.

I tried the following commands, but none of them worked. Only when I rebooted the device did hostapd start correctly.

ip link set wlan0 down
ip link set wlan0 up
rfkill unblock wifi

systemctl stop NetworkManager
systemctl stop wpa_supplicant

Has anyone encountered this problem? I reproduced this problem on the 6.1 kernel image, and finally I returned to the 5.4 historical image, and hostapd ran normally.

[ag123]

anything 'interesting' in dmesg? and what is the Armbian / kernel version? e.g.

uname -a

 

btw 'real' armbian is currently at linux version 6.12.x

btw I disabled wpa_supplicant when I run hostapd, I'm not sure if it'd affect anything, normally hostapd should work with wpa_supplicant running should be 'no problem'.

wpa_supplicant is 'connecting out', while hostapd is an AP hotspot.

The historical archive of armbian orange pi zero 3 seems to have been lost. I am currently using the 5.4 official image.

This is the current normal version output:

Linux orangepizero3 5.4.125 #1.0.8 SMP Wed Mar 19 23:35:12 CST 2025 aarch64 aarch64 aarch64 GNU/Linux
 

To investigate this issue, I continued to use Armbian_25.5.2_Orangepizero3_bookworm_current_6.12.30-homeassistant_minimal.img
 

Then uname -a output:

Linux orangepizero3 6.12.30-current-sunxi64 #2 SMP Thu May 22 12:29:54 UTC 2025 aarch64 GNU/Linux

I just tested shutting down hostapd and restarting, it works

systemctl stop hostapd.service
systemctl start hostapd.service

 

system process like hostapd should normally be properly started up and shutdown using systemd, killing the process etc may leave the kernel in inconsistent state. And maybe that's why you observe the issue.

 

this is how I set it up

accordingly, hostapd may require the interface to be on a bridge, I'm not sure about this, but that I'm using a (software) bridge so that the wifi interface is on it.

3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master br0 state forwarding priority 32 cost 100

 

I put both ethernet and wifi on the bridge, wifi is not managed by network manager, hostapd patch that into the bridge.

 

it is possible to just let hostapd setup the bridge in hostapd.conf, and normally that's all needed.

 

this isn't the earliest armbian I'm running hostapd in, i've done it since linux 6.6.x kernel an earlier release some 1 year back or so, no issues.
