If the driver for the wireless interface is not loaded in the `GENERIC` or custom kernel, and the computer is running FreeBSD {rel121-current}, load the corresponding [.filename]#.ko# in [.filename]#/boot/loader.conf# by adding `*driver_load="YES"*` to that file and rebooting.
-Another, better way is to load the driver in [.filename]#/etc/rc.conf# by adding it to `kld_list` (see man:rc.conf[5] for details) in that file and rebooting.

This is needed because otherwise the driver is not loaded yet at the time the man:lagg[4] interface is set up.

In this example, the Ethernet interface, _re0_, is the master and the wireless interface, _wlan0_, is the failover.
The _wlan0_ interface was created from the _ath0_ physical wireless interface, and the Ethernet interface will be configured with the MAC address of the wireless interface.
-First, bring the wireless interface up (replacing _FR_ with your own 2-letter country code), but do not set an IP address.

When the system boots, memory file systems for [.filename]#/etc# and [.filename]#/var# will be created and mounted and the contents of the [.filename]#cpio.gz# files will be copied into them.
By default, these file systems have a maximum capacity of 5 megabytes.
