To setup mulitple wlan profiles on FreeBSD and connect to them
automatically one can use `wpa_supplicant(8)`. To do this, add
following entries to rc.conf(5).

```
ifconfig_wlan0="WPA DHCP"
```

This tells the system to run `wpa_supplicant` and `dhcpd` on the
interface while coming up.

To store wifi profiles, use `wpa_supplicant.conf(8)`. For example, to
add a totaly made up WPA endpoint, append

```
network={
	ssid="apOne"
	psk="pass"
}
```

To add an open wifi (don't recommend this, but if you really want to)

```
network={
	ssid="CityLibrary"
   	key_mgmt=NONE
}
```

Now `wpa_supplicant` will search and connect you the next available
AP. You can control the order by setting the `priority` key. By
default all networks have priority 0, the higher value, the higher
priority.

This assumes you have setup your wireless card according to [FreeBSD
handbook](https://www.freebsd.org/doc/handbook/network-wireless.html).
