4. List wlan devices

sysctl -h net.wlan.devices

root@:/home/rjp # sysctl -h net.wlan.devices
net.wlan.devices: run0 ath0

5. Create wlan interface

ifconfig wlan1 create wlandev

root@:/home/rjp # ifconfig wlan1 create wlandev run0

6. Make /etc/wpa_suppicant.conf file

nano /etc/wpa_suppicant.conf

… my file


network={
ssid="rjpownnetwork"
proto=RSN
key_mgmt=WPA-EAP
eap=TLS
identity="loader"
ca_cert="/etc/certs/cacert.pem"
private:key="/etc/certs/clientkey.pem"
private:key_passwd="verysceredpassword"
}

7. Scan created wlan

ifconfig wlan1 up list scan

… my result after rebooting

SSID/MESH ID BSSID CHAN RATE S:N INT CAPS
rjpownnetwork c0:c9:e3:96:dc:e7 3 54M -26:-49 100 EP HTCAP WPA RSN WME WPS
