interface=wlan0 driver=nl80211 auth_algs=3 debug=0 logger_syslog=-1 logger_syslog_level=2 logger_stdout=-1 logger_stdout_level=2 dump_file=/tmp/hostapd.dump beacon_int=100 max_num_sta=255 hw_mode=a ieee80211n=1 wmm_enabled=1 ht_capab= channel=48 rts_threshold=2347 fragm_threshold=2346 ssid=ntest ctrl_interface=/var/run/hostapd ctrl_interface_group=0 ignore_broadcast_ssid=0 and the same setup as described above. In the trace, https://euterpe.cmi.ua.ac.be/~javonts/tmp/duplicateDump2.pcap , the problem arises only for ping reply sn: 4 and 'magically' resolves for the other pings. Any thoughts? Regards Jeroen
