No issue to start the AP alone with the minimal hostapd configuration

but failed when virtual station is already up.
Which channel is the station interface using here? The driver is
unlikely to support multiple different channels, so that could be
behind the issue.
Then hostapd gives following errors
~~~

That's not a real issue, i.e., that's fine to ignore. The real issue
would likely show up in the log either before or after this message.
Hello Jouni,
Thanks for the response. Good news is, everything is working after I
upgraded the system yesterday. Don't know, which software has fixed
it, but the hostapd version and configuration are still same. Only
issue, hostapd fails to run after ram hibernation. It shows
~~~
nl80211: Register frame command failed (type=176): ret=-114 (Operation
already in progress)
nl80211: Register frame match - hexdump(len=0): [NULL]
nl80211: Could not configure driver mode
nl80211: Remove monitor interface: refcount=0
nl80211: Remove beacon (ifindex=13)
~~~~
further checking shows a hostapd process is already exist at
background. Killing the same fixed the issue.
What can be done to handle this during hibernation ?
regards,
Bob
Hello Jouni & list,
I have come back again with the same issue "nl80211: Beacon set failed:
-16 (Device or resource busy)"
Sometime the AP works out off the box. But sometime it fails ( even
after reboot).
When fails it shows nothing in log but "hostapd -d" shows below. What
might be the reason ?
