Hi Martin,

thank you for your reply.

unfortunately, this does not change the behavior.


I switched off ifplugd for wlan0; then hostapd creates wlan0, changes
its mac according to the given bssid and creates the AP.
However, if I try to add a second ssid (just bss and ssid, no further
entries in hostapd.conf), I get the same errors again for the second AP:

nl80211: Create interface iftype 3 (AP)
nl80211: New interface wlan0:0 created: ifindex=3
nl80211: Add own interface ifindex 3
Could not set interface wlan0:0 hwaddr: Device or resource busy
nl80211: Remove interface ifindex=3
Failed to add BSS (BSSID=fa:XX:XX:XX:XX:41)
wlan0: Unable to setup interface.


It seems to me that hostapd is successful in creating wlan0:0, however,
wlan0 is already busy, and therefore the max of wlan:0 can not be set.
Is my assumption correct? And is there some way to solve that problem?

That's why I'm trying to set the mac/bssid.

It's 1.0

Thanks!
Best regards,
