Thanks a lot - kiitos!
That was clear and exact answer to my question and problem. I couldn’t
find any help from internet referring to this Beacon frames transmission
The adapter used is Ralink based Wi-PI dongle. It is using automatically
RT2800USB device driver.
Originally I had driver option in hostapd.conf as driver=nl80211 (kernel
Yesterday I did some fiddling with driver options and restarts.
Lsmod command is now showing mac80211 as loaded driver,
even current config still specifies nl80211?
What is best – last night my remote location wifi IPS camera been has woken
WORKS after more than one week.
May be there is some race condition which driver is picked up. Anyway
seems to correct? I have to study this a bit more.
Thank you for the help – Hostap seems to be robust and versatile software.
I’m now much more aware of its capabilities.

hostapd does not actually transmit the Beacon frames. It provides a
frame template to the kernel (driver or 802.11 stack) and the actual
transmission is coordinated by the WLAN driver (and/or firmware).
With some drivers (e.g., most drivers using mac80211), hostapd takes
care of Probe Request frame processing and sending of the Probe Response
frames (which have similar information to the Beacon frames).
