Hi, I am seeing regular "Michael MIC failure" syslog message in my /var/log/messages.
Jun 10 16:17:47 clyde /bsd: athn0: Michael MIC failure Jun 10 16:18:03 clyde /bsd: athn0: Michael MIC failure Jun 10 16:28:44 clyde /bsd: athn0: Michael MIC failure Jun 10 16:33:03 clyde /bsd: athn0: Michael MIC failure Jun 10 16:50:35 clyde /bsd: athn0: Michael MIC failure Jun 10 16:52:17 clyde /bsd: athn0: Michael MIC failure Jun 10 17:04:04 clyde last message repeated 2 times Jun 10 17:26:34 clyde /bsd: athn0: Michael MIC failure If I correctly understand the problem, Michael MIC failure is related to TKIP. But my network doesn't use TKIP but CCMP. $ ifconfig athn0 athn0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 lladdr e4:a4:a0:f1:fe:15 index 5 priority 4 llprio 3 groups: wlan egress media: IEEE802.11 autoselect (HT-MCS4 mode 11n) status: active ieee80211: nwid GUEST chan 6 bssid dc:08:56:15:be:14 -44dBm wpakey wpaprotos wpa2 wpaakms psk wpaciphers ccmp wpagroupcipher ccmp inet 192.168.1.107 netmask 0xffffff00 broadcast 192.168.1.255 Is it expected ? I did I miss something with Michael MIC failure ? Thanks. -- Sebastien Marie
