Wireless interface

[Carmel NY]

Okay, I had some free time today, so I decided to try and get the
wireless interface up and running on my FreeBSD 12.0 / amd 64 machine.
I thought I correctly configured the "wpa_supplicant.conf" file and
entered the correct into into the "/etc/rc.conf" file, but it is still
not working correctly. Anyway, this is the output when I attempt to restart the
network.

# service netif restart

The "/var/run/dhclient/dhclient.wlan0.pid" exists, so I am not sure
what that error message is all about. Plus, I have no idea what the
"sendmsg on em0: Permission denied" repeated three times is referring
to.

The "wpa_supplicant.conf file:
     network={
             ssid="Scorpio-2g"
             scan_ssid=1
             key_mgmt=WPA-PSK
             psk="SECRET"
     }

>From the "/etc/rc.conf file":
## Wireless
wlans_bwi0="wlan0"
ifconfig_wlan0="ssid Scorpio-2g DHCP"

the "dmesg" output for this device:
bwi0: <Broadcom BCM4318 802.11b/g Wireless Lan> mem 0xfdefe000-0xfdefffff irq 16 at device 1.0 on pci2

It is situations like this that make me love
Microsoft. Connecting a wireless network should not require user
intervention other than choosing the network and entering the password.
