Getting wireless network up and running

[Carmel]

I cannot seem to get my wireless network up and running.

/boot/loader.conf
if_bwn_load="YES"  # Broadcom BCM43xx IEEE 802.11 wireless NICs

/etc/rc.conf
## Wireless
wlans_bwn="wlan0"
ifconfig_wlan0="WPA SYNCDHCP"

/etc/wpa_supplicant.conf
network={
        ssid="Wireless-2g"
        psk="Secret"
        key_mgmt=WPA-PSK
}

I have run "service netif restart", but the network never comes up. I
tried rebooting, but still nothing.

If I append a "0" to bwn; ie, wlans_bwn0="wlan0", I get this output:

dhclient[1485]: short write: wanted 20 go 0 bytes
dhclient[1485]: exiting

The system is then frozen solid, so I am forced to reboot into single
user mode and remove the entry in "rc.conf".

Can anyone tell me what the problem is?

Thanks!
