The AP seems to receive traffic just fine, but is unable to send traffic over the interface. The first vap works fine. A ping example: stealth# ping 192.168.103.240 PING 192.168.103.240 (192.168.103.240): 56 data bytes ping: sendto: Network is down Log entries from dhcpd (it gets the request but can't send a reply): Jul 22 10:11:13 stealth dhcpd: DHCPDISCOVER from 00:1b:77:9d:ab:ba (jnielsengl1830) via wlan1 Jul 22 10:11:13 stealth dhcpd: DHCPOFFER on 192.168.103.240 to 00:1b:77:9d:ab:ba (jnielsengl1830) via wlan1 Jul 22 10:11:13 stealth dhcpd: send_packet: Network is down The problem seems to follow the second hostap device configured (e.g. wlan1). I've tested with ipfw turned off via sysctl and with and without hidessid and bgscan on both interfaces. I've also tried disabling WEP.
