freebsd wfi setup

hi,

i 've trouble to setup wifi. it can't find the wireless card.

it's a new install of freebsd 13. i've installed the ports :

/usr/ports/net/bwi-firmware-kmod/
/usr/ports/net/bwn-firmware-kmod/

with command "ifconfig" or "sysctl net.wlan.devices",

it doesn't list wireless cards.

with command "pciconf -lv", the card is :

none1@pci0:3:0:0: class=0x028000 rev=0x01 hdr=0x00 vendor=0x14e4
device=0x4365 subvendor=0x11ad subdevice=0x6605
    vendor     = 'Broadcom Inc. and subsidiaries'
    device     = 'BCM43142 802.11b/g/n'
    class      = network


in /etc/rc.conf

kld_list="linux nvidia nvidia-modeset if_ath if_bwi siba_bwn if_bwn
bwn_v4_ucode bwn_v4_lp_ucode bwn_v4_n_ucode if_wi wlan_wep wlan_ccmp
wlan_tkip"

### i've tried the three line below, it doesn't work.
#wlans_ath0="wlan0"
wlans_bwn0="wlan0"
#wlans_bwi0="wlan0"

ifconfig_wlan0="WPA SYNCDHCP"

can't load :
siba_bwn (the message is : no such file or directory)
if_wi wlan_wep wlan_ccmp wlan_tkip (the message is : unable to load kernel
module)


with command kldstat:
