Meu problema parece com este .
Eu configurei meu dispositivo Broadcom BCM4311 802.11b / g no FreeBSD 10.3-STABLE assim:
sudo kldload if_bwn
sudo kldload bwn_v4_ucode
sudo kldload bwn_v4_lp_ucode
#
# Now, interface 'bwn0' is available
#
sudo ifconfig wlan0 create wlandev bwn0
sudo ifconfig wlan0 up # at this moment, laptop WiFi LED light turns on
sudo ifconfig wlan0 scan # I can see my wireless router SSID
sudo wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf
sudo ifconfig wlan0 list sta
sudo dhclient wlan0
#
# Optionally, rather than dhclient run:
#
sudo ifconfig wlan0 inet 192.168.1.103 netmask 0xffffff00
ifconfig mostra o status da rede sem fio como associado:

Desconecto o cabo Ethernet do laptop para verificar a conexão sem fio com o roteador seguindo os métodos:
O roteador sem fio mostra que meu laptop está listado entre "Current Wireless Wireless Clients":
ID MAC
1 00:18:F3:38:A0:36
O roteador sem fio tem uma ferramenta de ping de diagnóstico pela qual posso fazer ping para o meu laptop, quando eu faço isso, a mensagem timed out é recebida:
IP Address/Domain Name: 192.168.1.103
Request timed out
Do meu laptop, faço ping para o roteador:
$ ping 192.168.1.1

Arquivos de configuração
Eu não uso /etc/rc.conf , faço tudo manualmente. Eu uso a seguinte configuração de wpa_supplicant :
$ cat /etc/wpa_supplicant.conf
network={
ssid="Mine"
psk=79a174594e2ec3563ff4c35c1a82a006b19df646fa020aaf53078d34d09ed962
}
$
Eu me pergunto se alguém pode dar uma mão.
ATUALIZAÇÃO:
Agora, estou usando /etc/rc.conf da seguinte forma:
#
