Hi everybody!
On the wui configuration page wlanap.cgi, the access point shows “running” and also the green field, although the hostapd task has been stopped. The only difference between “running” and “stopped” is that in the case of “stop” no PID or used memory is displayed. And, of course, that the access point is not reachable - as expected.
Hope I’m not the only one.

The wlanap.cgi shows “running” if the wlancard is set to ap mode. Usually this is done by hostapd and set back if hostapd terminate. Sounds like hostapd is crashed on your system after switching the card to ap-mode.
Hi Arne,
thank you for your time!
I was looking at the logs but can’t find any info about what is going wrong with hostapd. For me nothing to find in error_log and messages.
When stopping access point via wui button /var/log/messages says:

Thy in advance for any help!
Hi again!
Sorry for bothering your time. After reboot it works as expected. Real noob failure: First reboot, then ask.
