Write the following section to /etc/rc.conf.

kld_list="if_iwlwifi"
wlans_iwlwifi0="wlan0"
wlandebug_wlan0="+state +crypto +node +auth +assoc +dot1xsm +wpa"
ifconfig_wlan0="WPA SYNCDHCP"

Create /etc/wpa_supplicant.conf.

network={
ssid="WIFI name (SSID)"
psk="WIFI password"
}

Lload the driver.

# kldload if_iwlwifi

Note: The following section must be executed once per boot to be able to
network.

Create and link.

# ifconfig wlan0 create wlandev iwlwifi0
# /etc/rc.d/netif start wlan0
