From: Ilan Peer <ilan.peer@xxxxxxxxx> When hostapd sends a probe response, it does not request an acknowledgment on the probe response. This setting is propagated to the driver and FW from mac80211, and as a result probe responses are transmitted only once without retries. In congested environments, this reduces the likelihood for finding the AP. To overcome this, enable acknowledgment and retries for probe responses, even in case no acknowledgment is requested. In such a case the retry limit is set to 3.
